The inductor works well in high idle current applications, or at high temperatures, where the inductance value needs to remain stable over thermal cycle changes. The inductance range of the 4922-52H can be from 2- 50 microHenries, offering a variety of applications in higher current demands with able power supply. Additionally,the 4922-52H has an inductance tolerance of K between 10% to 30%. These features make the 4922-52H perfect for creating a reliable high-efficiency power supply with high temperature-resistant performance.

Fixed inductors store energy in a magnetic field and are important for supporting the fluctuating current in the automotive environment. The 4922-52H provides an alternating current filter with high temperature resistance and improved dissipation. Working together with the EMI filter, the inductor helps the filter function in a digital environment.

The 4922-52H fixed inductors have a robust design and are manufactured using an alloy-metal core and a ferrite mounting flange. This allows for uniform thermal transport and convective cooling over the die-cast core, providing a stable inductance level from 0 to 100°C. The inductor is manufactured with a 30-60 msec rise time for applications that require high-speed operational performance. The 4922-52H inductor is also available with either flying lead or radial lead. Both types of the inductor have a high self-resonance frequency of 2-30MHz and a saturation current range of 2-50A.

In order to create a reliable power supply for automotive applications, a choke needs to have a low distributed capacitance. This is what the 4922-52H achieves, thanks to the Low-ESL (equivalent series inductance). The combination of the low inductance tolerance, high thermal performance, and low distributed capacitance makes the 4922-52H an ideal choice for raising the efficiency of the power supply in an automotive electronic circuit.

The 4922-52H is a reliable and versatile component for use in various automotive electronic applications.
