YAGEO’s new JXF0‑series PulseJack integrated connector modules (ICMs) combine a compact RJ45 jack with integrated magnetics and 90 W PoE+ capability for 1G, 2.5G and 5G Ethernet in a single footprint.
This makes the YAGEO connector device attractive for space‑constrained industrial, networking and embedded designs that need to scale from legacy Gigabit to multi‑Gig rates without re‑laying the PCB.
The series targets applications where board area, thermal headroom and manufacturing efficiency are all under pressure, such as industrial switches, wireless access points, security equipment and embedded controllers. It addresses these constraints with a smaller footprint, wide operating temperature range and compatibility with modern reflow processes according to JEDEC J‑STD‑020F.
Key features and benefits
- Multi‑rate Ethernet in one footprint – One RJ45 ICM family supports 1G, 2.5G and 5G Base‑T Ethernet in the same mechanical footprint, allowing OEMs to design a single PCB that can populate different data‑rate SKUs without layout changes.
- 90 W PoE+ support (IEEE 802.3bt) – Compliant with IEEE 802.3bt, enabling 4‑pair power delivery up to 90 W (approximately 900 mA) over twisted pair cabling, suitable for power‑hungry powered devices such as high‑end access points, PTZ cameras or industrial nodes.
- Compact footprint with reduced PCB area – Typical dimensions of approximately 25.5 × 16.8 × 13.5 mm help save around 25% PCB area compared to earlier PulseJack solutions, freeing space for additional circuitry or enabling smaller form factors.
- Wide industrial temperature range – Specified for operation from −40 to +85 °C, making the series suitable for industrial and outdoor equipment where ambient temperature and self‑heating margins are critical.
- Bi‑color LED indicators – Integrated LED options support link and activity indication (for example green/amber), simplifying front‑panel design and helping technicians quickly diagnose link state and speed.
- Robust construction and certifications – Modular construction with auto‑wound magnetics, UL certification, and compliance with RoHS, REACH and halogen‑free requirements support long‑term reliability and regulatory compliance in global markets.
- Modern assembly compatibility – Designed for wave and IR reflow soldering, with Pin‑in‑Paste (PiP) / Through‑Hole Reflow (THR) compatibility and Moisture Sensitivity Level (MSL) 1 according to JEDEC J‑STD‑020F, easing high‑volume SMT assembly.
Typical applications
JXF0‑series PulseJack ICMs target networking and industrial systems where designers want to combine multi‑Gigabit data with high‑power PoE+ in a compact connector solution.
- Industrial Ethernet switches and managed switches in factory automation
- Copper and Wi‑Fi routers supporting multi‑Gig uplinks or LAN ports
- Network interface cards (NICs) and embedded network modules in industrial PCs
- Process control equipment and PLCs with Ethernet fieldbus connections
- Embedded computing boards with RJ45 front panel connectors
- LTE and other wireless access points powered via PoE+
- Security and access control systems, including high‑power PTZ IP cameras
- Remote powered sensing nodes and distributed I/O devices in building automation
These segments often require long cable runs, higher ambient temperatures and tight enclosures, so the combination of PoE+, compact footprint and wide temperature range is particularly relevant.
Technical highlights
This section summarizes the key technical characteristics as presented in the manufacturer materials. Exact numerical values and per‑part variations should always be confirmed in the relevant YAGEO / Pulse datasheet.
Electrical and functional characteristics
- IEEE 802.3 Gigabit compliant magnetics and RJ45 interface
- Support for 1G, 2.5G and 5G Base‑T data rates in a single mechanical platform
- IEEE 802.3bt compliance enabling up to 90 W PoE+ over four pairs
- Support for remote DC power feed over the same cable as Ethernet data
- Integrated magnetics designed for isolation, common‑mode noise rejection and EMI control according to Ethernet requirements
In practice, IEEE 802.3bt support means that powered devices can draw significantly more power than older PoE/PoE+ standards, reducing the need for local DC supplies at the end equipment. Multi‑rate capability allows system designers to ship lower‑cost 1G variants and higher‑speed 2.5G/5G variants from the same base hardware.
Mechanical and environmental characteristics
- Compact RJ45 ICM with approximate dimensions of 25.5 × 16.8 × 13.5 mm
- Approximate 25% PCB area reduction compared to legacy PulseJack solutions in the same class
- Industrial operating temperature range from −40 to +85 °C
- UL certified modular construction with automated coil winding for consistency
- RoHS, REACH and halogen‑free compliant materials
The compact size and reduced PCB area can be important in dense front panels with many RJ45 connectors or in small embedded systems, where each millimeter of board edge is valuable.
Assembly and compliance characteristics
- Designed for wave soldering and IR reflow processes
- Pin‑in‑Paste / Through‑Hole Reflow compatible lead design
- JEDEC J‑STD‑020F compliant with a peak reflow temperaurer materials. EC
- Moisture Sensitivity Level (MSL) 1, simplifying storage and handling
From a manufacturing standpoint, PiP/THR compatibility means the connector can be inserted in the PCB and soldered in the same reflow process as surface‑mount components, reducing secondary wave‑solder steps and lowering assembly cost.

Design‑in notes for engineers
This section provides practical guidance for integrating the JXF0‑series PulseJack RJ45 ICM into new or existing designs.
- Plan for multi‑rate support from the outset – Since the JXF0 platform supports 1G, 2.5G and 5G in a single footprint, consider laying out the board and choosing MAC/PHY devices that can scale across these speeds, enabling later performance upgrades without mechanical redesign.
- Confirm PoE power budget and thermal headroom – Although IEEE 802.3bt allows up to 90 W, actual usable power depends on cable losses, ambient temperature and enclosure design; ensure that the RJ45 area has sufficient airflow or thermal coupling for industrial environments.
- Check PHY compatibility and magnetics requirements – Verify that the chosen Ethernet PHY matches the recommended transformer ratios, insertion loss and common‑mode specifications given in the JXF0‑series datasheets, and follow YAGEO’s example schematics for optimal EMI performance.
- Use appropriate PCB land patterns and PiP stencil design – For Pin‑in‑Paste / THR assembly, follow YAGEO’s recommended pad sizes and stencil apertures to ensure reliable solder fill and avoid voids or disturbed joints during reflow.
- Pay attention to creepage and clearance around the connector – PoE and Ethernet isolation requirements may impose minimum distances around the magnetics and RJ45 shield; avoid routing high‑speed or sensitive traces too close to the connector pins.
- Leverage integrated LEDs for diagnostics – Choose LED color combinations that clearly differentiate link vs activity and speed (for example, one color for link, another for higher data rates) to simplify field diagnostics.
- Design for serviceability and EMC – Provide accessible test points for common‑mode chokes and PHY pins, and follow good EMC practice around the connector (grounding, shield connection, stitching vias) to minimize emissions and susceptibility.
- Coordinate with mechanical engineering early – The smaller 25.5 × 16.8 mm footprint helps in dense front panels, but stacked connectors, labels and cut‑outs still need mechanical coordination to maintain plug accessibility and strain relief.
For safety‑related or outdoor systems, always cross‑check isolation, surge and ESD requirements against the most recent YAGEO datasheets and application notes according to manufacturer documentation.
