Overview
The WCM2012F2SF-181T03 is a two-line surface mount common mode choke manufactured by TAI-TECH Advanced Electronics Co., Ltd. It features a compact wire-wound design with dimensions of 2.0 x 1.2 x 1.2 mm. The component provides a common mode impedance of 180 Ohms at a test frequency of 100 MHz. It supports a rated current of 350 mA and maintains a low DC resistance (DCR) of 350 mOhm. The device operates within a temperature range of -40°C to +125°C and complies with RoHS standards.
Feature Summary
- Compact surface mount footprint suitable for space-constrained designs
- Low profile construction for efficient board integration
- Lead-free and halogen-free composition ensuring environmental compliance
Applications
- High-speed data line noise suppression
- Portable electronic device signal filtering
- Consumer electronics EMI mitigation
Procurement Notes
Verify the specific suffix 'T03' against official manufacturer documentation to confirm packaging specifications and tolerance ratings. Ensure that the requested quantity aligns with standard reel sizes or minimum order requirements defined in the current datasheet. Confirm lead times directly with authorized distributors as availability may vary by region and batch.
Selection Notes
Select this component when a low-profile, high-impedance filter is required for differential signal lines carrying currents up to 350 mA. The 180 Ohm impedance at 100 MHz makes it suitable for suppressing noise in high-frequency digital interfaces. Consider the 350 mOhm DCR for power loss calculations in sensitive circuits requiring minimal voltage drop across the filter.
Part Context
This part belongs to the WCM2012F2SF series from TAI-TECH, which specializes in wire-wound common mode filters. The series is characterized by its small 2.0x1.2mm footprint and suitability for automated surface mount assembly processes. It serves as a specialized solution for electromagnetic interference reduction in modern compact electronic assemblies.
Replacement Considerations
Cross-reference with other WCM2012F2SF variants such as WCM2012F2SF-221T03 or WCM2012F2SF-670T04 if different impedance levels are needed. Verify pin compatibility and physical dimensions before substituting with components from other manufacturers to ensure mechanical fit and electrical performance alignment.
