The ECMF4-40A100N10 is a surface mount common mode choke from STMicroelectronics designed for signal line EMI filtering. It provides four lines of filtering and is rated for a maximum current of 100mA, making it suitable for low-current signal applications. The component also integrates ESD protection to help safeguard downstream circuitry.
Electrically, the choke presents a DC resistance of 3 ohm (typical) and operates over a temperature range of -55°C to 125°C. Its compact 10-XFDFN package measures 2.20mm x 1.35mm with a maximum height of 0.50mm, enabling use in space-constrained PCB layouts.
The filter type is classified as signal line, and the component is qualified for surface mount assembly. With built-in ESD protection, it is well suited for applications where both common mode noise filtering and electrostatic discharge robustness are required. The wide operating temperature range supports use in a broad range of operating environments.
