WCM3216F2SF-221T03

Overview

The WCM3216F2SF-221T03 is a surface-mount common mode filter manufactured by TAI-TECH Advanced Electronics Co., Ltd. It features a compact SMD package with dimensions of 3.20mm length, 1.60mm width, and a maximum height of 1.30mm. The component provides an inductance of 220µH with a tolerance of ±25%. It operates within a temperature range of -40°C to +125°C. Key electrical specifications include a maximum DC resistance of 450mΩ, a current rating of 300mA, and a DC voltage rating of 50V.

Feature Summary

• High common mode impedance at high frequencies for effective noise suppression
• Compact and thin surface mount design suitable for space-constrained applications
• Lead-free and halogen-free construction compliant with RoHS standards

Applications

• Noise filtering in high-frequency signal lines
• EMI suppression in portable electronic devices
• Signal integrity protection in compact circuit boards

Procurement Notes

Verify the specific suffix (T03) against official datasheets to confirm physical dimensions and packaging type. Ensure compatibility with automated pick-and-place equipment due to the small SMD footprint. Confirm RoHS compliance status if required by final assembly regulations. Check storage conditions to maintain component integrity prior to soldering.

Selection Notes

Select this component when high-frequency noise attenuation is required in limited board space. The 300mA current rating suits low-power signal lines rather than high-current power paths. Verify that the 450mΩ DC resistance meets the circuit's voltage drop requirements. Ensure the operating temperature range aligns with the environmental conditions of the target application.

Part Context

This part belongs to the WCM series of wire-wound common mode filters from TAI-TECH. The series is characterized by its small form factor and high impedance performance. The WCM3216F2SF variant specifically denotes the 3.2x1.6mm footprint family, designed for modern miniaturized electronics requiring efficient EMI control without occupying significant PCB area.

Replacement Considerations

Cross-reference with other 3.2x1.6mm common mode chokes offering similar 220µH inductance and 300mA ratings. Ensure substitute components match the 1.30mm height limit and 450mΩ DCR specifications. Verify that alternative parts maintain comparable high-frequency impedance characteristics for equivalent noise suppression performance.
