ECMF04-4HSM10Y Description

Short technical summary and product information.

The ECMF04-4HSM10Y is a common mode choke (CMC) from STMicroelectronics designed for signal line EMI filtering. It provides four lines of filtering in a compact surface mount package, with integrated ESD protection for enhanced robustness in electronic systems.

 

The component is rated for a maximum current of 100mA and has a DC resistance of 5Ω (listed as typical). It operates over a temperature range of -55°C to 125°C, making it suitable for a wide variety of environments.

 

The device is supplied in a 10-UFDFN package with dimensions of 2.60mm x 1.35mm x 0.55mm. It is assembled using surface mount technology, which supports automated PCB manufacturing and space-constrained designs.

 

With its 4-line configuration and ESD feature, the ECMF04-4HSM10Y is appropriate for suppressing common mode noise on data or signal lines while providing transient protection.
