Vishay Intertechnology new release of IHVR vertical mount inductor series in 4025 case size save space while enabling low DCR and high rated current for increased efficiency.
The IHVR-4025JZ-3Z space-saving vertical-mount inductor in the 4025 case size features a unique coil conductor shape that optimizes inductance and minimizes DCR for increased efficiency in DC/DC converters.
Vishay Intertechnology, Inc. introduced a new IHVR vertical-mount inductor in the 10.25 mm by 6.4 mm by 10 mm 4025 case size. Optimizing inductance and minimizing DCR for increased efficiency in DC/DC converters, the newly designed Vishay Dale IHVR-4025JZ-3Z offers high temperature operation up to +155 °C for computer, server, telecom, and industrial applications.
Compared to traditional inductors, the compact size and unique vertical-mount design of the device released today save on board space and allow for more efficient cooling by utilizing air flow while enabling 50 % lower DCR down to 0.130 mΩ (typical) and higher rated current up to 112 A. The device’s reduced DCR can provide significant savings in energy costs over the life of a server compared to less-efficient solutions. In addition, its rectangular shape provides better integration with other board components, making it easier for designers to keep PCB trace lengths equal to reduce phase imbalances.
The IHVR-4025JZ-3Z is optimized for energy storage in DC/DC converters up to 5 MHz and high current filtering applications up to the SRF of the inductor. Applications for the device include desktops and servers; low profile, multi-phase, high current power supplies; POL converters; and distributed power systems and FPGAs. In these applications, the inductor offers extremely stable inductance and saturation over the full -40 °C to +155 °C operating temperature range.
Packaged in a 100 % lead (Pb)-free shielded, composite construction that reduces buzz noise to ultra low levels, the IHVR-4025JZ-3Z offers high resistance to thermal shock, moisture, and mechanical shock and handles high transient current spikes without saturation. The device is RoHS-compliant, halogen-free, and Vishay Green.
