ECMF04-4HSWM10Y Description

Short technical summary and product information.

The ECMF04-4HSWM10Y is a surface-mount common mode choke designed for signal line filtering. It integrates four lines in a compact 10-WFDFN package with a wettable flank mounting style, suitable for automated inspection processes. The device operates over a temperature range of -55°C to 125°C, making it suitable for harsh environments.

 

With a maximum current rating of 100mA and a typical DC resistance of 5.5Ω, this choke is optimized for low-power signal applications. The built-in ESD protection feature helps safeguard downstream circuitry from electrostatic discharge events. Rated to AEC-Q200 standards, it is intended for automotive electronics and other reliability-critical systems.

 

The package dimensions are 2.60mm x 1.35mm with a maximum height of 0.80mm, offering a compact footprint for dense PCB designs. The wettable flank terminals improve solder joint inspectability, which is beneficial for quality control in manufacturing.
