EPS editor’s note: The most ubiquitous components in any electronics design – interconnects, passives and electromechanical (IP&E) devices – are in the midst of an unprecedented supply shortage. What distinguishes this scarcity from others is the broad base of markets that are desperate for IP&E. (more…)

At the time of powering on an electronic device such as a switch-mode power supply (SMPS) or an inverter, the device is charged with an instantaneous abnormal current with a high peak. It is called an inrush current, and without protection, it may destroy a semiconductor device or have a harmful effect on the service life of a smoothing capacitor. NTC thermistors are used as ICLs (inrush current limiters) to protect circuits of electrical and electronic devices against inrush currents easily and effectively.

Written by Ekaterina Rachel, Product Manager, Passive. Instant power, always on, disposable, or not. Traditional battery technologies are being challenged by a relatively new kid on the block, the supercapacitor, and forcing developers across a range of battery-powered applications to examine just what and when power is needed for their system.

Electromagnetic (EM) radiation from inductors in DC/DC converters is no triviality — especially when considering the type and proximity of surrounding components and their susceptibility to magnetic coupling. In this post, we will discuss EM radiation as it pertains to unshielded, semi-shielded, and shielded inductors. We will also cover how EM radiation changes according to different influences. (more…)

High-power loads are a major stress factor when fuses and components are switched on, as they cause very high currents to flow. To avoid this, TDK offers ceramic EPCOS inrush current limiters (ICLs), based on NTC and PTC thermistors – a strong duo when used in combination. (more…)
