Overview
The WCM 2012F2SF-801-N is a wire wound type common mode filter manufactured by TAI-TECH Advanced Electronics Co., Ltd. It features a surface mount package with dimensions of 2.00mm x 1.20mm x 1.20mm. The component operates within a temperature range of -40°C to +125°C and has a DC voltage rating of 50V. Key electrical specifications include an inductance of 800 Ohms at 100 MHz, a maximum current rating of 300mA, and a DC resistance (DCR) of 880mOhm.
Feature Summary
- Wire wound construction for effective common mode noise suppression
- Compact horizontal surface mount design suitable for space-constrained PCBs
- RoHS compliant manufacturing process
Applications
- High-speed data line filtering
- USB interface noise suppression
- HDMI signal integrity protection
Procurement Notes
Verify the specific ordering suffix 'N' corresponds to the required tape and reel packaging configuration. Confirm that the 800 Ohms impedance at 100 MHz aligns with the target frequency spectrum of the application. Ensure the 300mA current rating exceeds the maximum operational current of the protected circuit to prevent saturation or thermal issues during peak load conditions.
Selection Notes
Select this component when a compact 2-line common mode choke is required for high-frequency noise attenuation. The 2012 footprint offers a balance between size and performance. Consider the 880mOhm DCR impact on signal loss if used in low-voltage differential signaling applications. Verify compatibility with standard reflow soldering profiles as specified by the manufacturer.
Part Context
This part belongs to the WCM 2012F2SF series of wire wound common mode filters from TAI-TECH. The series utilizes a horizontal pad configuration designed for automated surface mount assembly. The product status is listed as active, indicating ongoing production and availability for new designs.
Replacement Considerations
Direct substitutes must match the 2012 package dimensions, 800 Ohms @ 100 MHz impedance, and 300mA current rating. Verify pinout compatibility and thermal characteristics before substitution.
