Overview
The TCM0906C-400-3P-T200 is a three-line common mode choke filter designed for high-speed signal lines. It features an impedance of 40 Ohms at 100 MHz and supports a maximum DC current of 100 mA with a maximum DC resistance of 3 Ohms. The component operates within a temperature range of -25°C to +85°C. Its physical dimensions are 0.875 mm in length, 0.65 mm in width, and 0.4 mm in height, utilizing SMD/SMT mounting on a PCB.
Feature Summary
- Designed specifically for high-speed differential signal line applications
- Provides effective common mode noise suppression in compact form factors
- Capable of handling specified DC currents without saturation
Applications
- High-speed USB interfaces
- HDMI signal protection
- DisplayPort data lines
Procurement Notes
Verify the specific suffix T200 against official TDK documentation to confirm reel specifications and tape-and-reel parameters. Ensure the procurement channel provides valid RoHS compliance certificates. Cross-reference the manufacturer part number with authorized distributor databases to prevent counterfeit components. Confirm that the delivered units match the exact electrical characteristics defined in the latest datasheet revision.
Selection Notes
Select this component when space constraints require a 0302 package size for high-speed data lines. The 40 Ohm impedance rating must align with the target frequency spectrum of the noise to be suppressed. Verify that the 100 mA current rating exceeds the peak operating current of the signal lines. Consider the low DC resistance to minimize signal attenuation and voltage drop across the filter.
Part Context
This component belongs to the TCM-S series of common mode chokes from TDK. The series focuses on miniaturized solutions for portable electronics and high-density PCB layouts. It complements other TCM variants by offering specific impedance and current ratings tailored for modern digital interfaces requiring robust EMI mitigation.
Replacement Considerations
Consult TDK's official substitution guide for equivalent parts within the TCM-S series. Verify that any alternative maintains the same 0302 footprint and 40 Ohm impedance profile. Ensure the replacement meets the same thermal and current handling requirements.
