STMicroelectronics 4-Element EMI Filter & ESD Protector Surface Mount, 10-Pin QFN ECMF04-4HSWM10

STMicroelectronics ECMF04-4HSWM10 is a highly integrated 4-element EMI filter and ESD protector incorporating a complex diode array in a surface mount QFN 10-pin package. Designed for suppressing electromagnetic interference (EMI) and radio frequency interference (RFI) on high-speed differential serial buses such as MIPI D-PHY, MDDI, and USB 2.0 interfaces, this device enhances signal integrity in demanding electronic environments.

This component is engineered to protect sensitive electronic circuits against transient voltage surges and electrostatic discharges, meeting stringent operating temperature requirements from -40°C to 85°C suitable for automotive and industrial applications. The device features a minimum breakdown voltage of 4.5V, a maximum reverse stand-off voltage of 3V, and a maximum reverse leakage current of 100nA, ensuring low power loss during standby.

Its compact form factor with dimensions of 2.65mm length, 1.4mm width, and 0.5mm height allows for efficient mounting on high-density PCBs while maintaining robust filter performance. The integrated ESD protection improves device longevity and system reliability in harsh environments.

4 elements per chip provide comprehensive EMI and ESD filtering capabilities. Surface mount QFN package supports automated assembly and compact design. Complex diode array optimizes noise suppression on high-speed serial buses.

Operating temperature from -40°C to 85°C broadens application scope. Pin count of 10 supports multiple signal and ground paths. Minimum breakdown voltage 4.5V delivers reliable surge tolerance. Maximum reverse stand-off voltage 3V prevents damages from voltage spikes.

Test current rating of 1mA ensures standardized electrical performance. Low reverse leakage current of 100nA enhances efficiency and reduces heating. Compact dimensions conserve PCB space in dense electronic assemblies.

This EMI filter and protector is ideal for use in industrial, automotive, communication equipment, and consumer electronics where EMI suppression and ESD protection are essential for product reliability and compliance. It supports system design optimization by reducing electromagnetic noise and shielding critical components from voltage transients.
