Overview
The WCM 2012F2SF-670T04 is a two-line common mode choke manufactured by Tai-Tech Advanced Electronics Co., Ltd. in the 0805 (2012 Metric) surface-mount package. It features an impedance of 67 Ohms at 100 MHz and supports a current rating of 400 mA with a DC resistance of 250 mOhm. The component measures 2.0 x 1.2 x 1.2 mm, ensuring compact integration. It complies with RoHS standards and contains no lead or halogen.
Feature Summary
- High common mode impedance at high frequencies for effective noise suppression
- Compact 0805 footprint with thin profile design
- Lead-free and halogen-free construction compliant with environmental standards
Applications
- High-speed data line protection
- Noise filtering in portable electronic devices
- EMI suppression in compact circuit boards
Procurement Notes
Verify the exact part number against manufacturer documentation to ensure compatibility with specific circuit requirements. Confirm that the 400 mA current rating and 250 mOhm DC resistance meet the design specifications. Ensure the 0805 package dimensions fit the available board space. Check for RoHS compliance if required by project regulations.
Selection Notes
Select this component when high-frequency noise suppression is critical in space-constrained designs. The 67 Ohm impedance at 100 MHz makes it suitable for high-speed signal lines. Consider the 400 mA current limit during selection to prevent saturation. The small 2.0 x 1.2 mm size allows for dense PCB layouts without compromising performance.
