SCRH123-680

Fixed Inductors Overview

The SCRH123-680 is a fixed surface-mount power inductor from the SCRH series by Signal Transformer. It features a wirewound ferrite core and is shielded to minimize electromagnetic interference. The component provides an inductance of 68 µH with a tolerance of ±30%. It supports a maximum current rating of 1.28 A, which corresponds to both the saturation current (Isat) and the RMS current rating. The DC resistance (DCR) is specified at a maximum of 354 mΩ. Testing for inductance is conducted at 100 kHz. The device operates within a temperature range of -40°C to +125°C and utilizes a non-standard SMD package.
