Overview
The WCM3216F2SF-161T03 is a two-line surface mount common mode choke manufactured by TAI-TECH Advanced Electronics Co., Ltd. It features an impedance of 160 Ohms at 100 MHz with a tolerance of ±25%. The component has a DC resistance (DCR) of 0.40 Ohms and a maximum rated current of 350 mA. It supports a voltage rating of 50 V DC and operates within a temperature range of -40°C to +125°C. The physical dimensions are 3.20 mm in length, 1.60 mm in width, and 1.00 mm in height.
Feature Summary
- Provides common mode noise suppression for high-speed signal lines
- Designed for compact surface mount assembly on printed circuit boards
- Constructed with wire wound technology for effective filtering
Applications
- High-speed data interface protection
- USB port noise filtering
- HDMI signal line interference reduction
Procurement Notes
Verify the specific suffix T03 against the manufacturer's datasheet to confirm packaging details and tape-and-reel specifications. Ensure the ordered quantity aligns with standard reel sizes to avoid partial reel handling issues. Confirm that the 350 mA current rating meets the operational requirements of the target circuit under all expected thermal conditions.
Selection Notes
Select this component when a low-profile 3216 package is required for space-constrained designs. The 160 Ohm impedance at 100 MHz makes it suitable for frequencies typical of USB 2.0 or similar digital interfaces. Verify that the 0.40 Ohm DCR does not cause excessive voltage drop in the power or signal path relative to the system's performance thresholds.
Part Context
This part belongs to the WCM3216F2SF series from TAI-TECH, which offers various impedance values within a standardized 3.2x1.6mm footprint. The series is designed for applications requiring efficient common mode noise attenuation in small form factor electronics. The specific model indicates a 160 Ohm characteristic impedance at the standard test frequency.
Replacement Considerations
Compatible substitutes include other 3216 package common mode chokes with similar impedance and current ratings. Verify pin compatibility and mechanical dimensions before substitution. Ensure the alternative component meets the same operating temperature range and voltage rating requirements.
