Overview
The WCM2012F2SV-201T03 is a surface mount common mode choke from TAI-TECH Advanced Electronics. It features a ceramic core and operates within a temperature range of -40°C to +125°C. The component provides an impedance of 200 Ohms at 100 MHz with a maximum DC resistance of 400 mOhm. It supports a rated current of 300 mA and withstands voltage as specified in the datasheet. The package is 0805 (2012 Metric) with four pads for mechanical stability.
Feature Summary
- Utilizes a ceramic core material for stable electromagnetic performance
- Designed for surface mount assembly with four-pad configuration
- Provides effective common mode noise suppression for data lines
Applications
- Data line filtering in electronic circuits
- Noise suppression in portable devices
- Signal integrity protection in consumer electronics
Procurement Notes
Verify the specific impedance value and DC resistance against the official TAI-TECH datasheet before procurement. Ensure the operating temperature range meets your application requirements. Confirm the package dimensions match your PCB footprint design. Check for any specific handling instructions regarding the ceramic core construction.
Selection Notes
Select this component when a compact 0805 footprint is required for common mode noise reduction. Consider the 300 mA current rating and 400 mOhm DCR for power efficiency needs. The ceramic core offers thermal stability suitable for environments up to 125°C. Evaluate the 200 Ohm impedance at 100 MHz against the target noise frequency spectrum.
Part Context
This part belongs to the WCM_V series of wire wound common mode chokes by TAI-TECH. It shares the 2012 metric package size with variants like WCM2012F2SV-221T03 but differs in impedance characteristics. The series is designed for general-purpose data line filtering applications requiring small form factors.
Replacement Considerations
Direct substitutes may include other 0805 common mode chokes with similar 200 Ohm @ 100 MHz impedance and 300 mA current ratings. Verify pin compatibility and physical dimensions before substitution. Consult TAI-TECH for recommended alternatives if exact replacement is unavailable.
