KEMET SBC Series Ferrite Power Inductor 33uH, 1.7A

The KEMET SBC Series Ferrite Power Inductor provides reliable, high-performance energy storage and filtering for demanding electronic circuits. Designed with a durable drum core construction using a nickel-zinc (NiZn) ferrite core, it offers excellent magnetic properties in a compact, unshielded form factor. This inductor is engineered to handle significant current, with an RMS current rating of 1.7A and a saturation current of 1.8A, making it a robust choice for power management applications.

A key feature is its wide operating temperature range of up to +105°C, ensuring stable performance even in warm environments found within enclosed electronic devices. With a low DC resistance of just 0.09ohm, it minimises power loss and heat generation, contributing to overall system efficiency. The component is supplied with an inductance tolerance of ±20%, providing flexibility for a broad range of circuit designs.

Typical Applications

This versatile inductor is a fundamental component in modern power electronics. Its primary uses include serving as a choke in DC/DC converters for voltage regulation and acting as an effective noise filter to suppress electromagnetic interference (EMI). You will commonly find it in power supplies for consumer and industrial equipment, LED lighting drivers, telecommunications devices like xDSL modems, office equipment such as copying machines, consumer electronics including flat-screen televisions, and smart metering infrastructure.
