PE-0403MCMC900ST

Common Mode Chokes Overview

The PE-0403MCMC900ST is a two-line common mode choke manufactured by Pulse Electronics, designed for surface mount applications. It features an impedance of 90 Ohms at 100 MHz and supports a maximum current rating of 100 mA. The component has a maximum DC resistance (DCR) of 4.5 Ohms and operates within a temperature range of -40°C to 85°C. Housed in a compact 0403 (1210 metric) package with four leads, it measures 1.25mm in length, 1.00mm in width, and 0.65mm in height. This signal line filter is rated for 5V DC.
