Energieopslagcircuit voor de auto-inductor

Why are inductors used in automotive ECUs?

With their smoother saturation characteristic, these inductors enable DC/DC switching power supplies to maintain stability over a wide temperature range and handle large load transients or high-inrush conditions, and hence are well suited to use in automotive ECUs.

What are automotive-qualified inductors?

Automotive-qualified inductors leveragemetal-composite core technology can offer designers improved permeability and saturation characteristics to deliver stable, reliable, and energy-efficient filtering and current smoothing to the increasing number of ECUs on-board today’s vehicles.

Are thin-film power inductors good for automotive applications?

In particular, thin-film power inductors designed for automotive applications—which combine TDK’s proprietary thin-film and long-cultivated magnetic material technologies to produce characteristics unavailable in conventional products—offer superior properties and high reliability despite their compact size.

Why should automotive inductors have low DC resistance?

In addition to offering improved saturation characteristics and stability over a wide temperature range, inductors for automotive applications should also offer low DC resistance to avoid unwanted self-heating and minimize energy losses thereby contributing to increasing overall vehicle efficiency.

What is a power inductor?

The power inductor is a critical component that determines the performance of these converters. Inductors pass direct current (DC) freely while behaving like resistance against alternating current (AC). When coupled with ICs that perform high-speed switching, they enable DC-DC converters to convert voltages to the required levels.

What is the global demand for automotive inductors?

With the growing number of ECUs installed in cars, demand is surging for electronic components like inductors, capacitors, and EMC products. Global demand for automotive inductors is expected to continue expanding, approximately doubling that of 2020 by 2030. (Based on research by TDK)
