Overview
The TCM0403M-350-2P-T210 is a surface-mount common mode choke from the TCM-M series, designed for high-speed signal filtering. It features a 0403 (0907 metric) package with dimensions of 0.45 mm length. Key electrical parameters include an inductance of 140 nH with a 30% tolerance and a maximum DC resistance of 2 ohms. The component supports a maximum DC current of 50 mA and operates within a temperature range of -25°C to +85°C. It is rated for 5VDC and provides effective filtering at frequencies up to 2.4 GHz.
Feature Summary
- Thin-film technology enabling ultra-high-speed signal integrity
- Compact 0403 footprint suitable for dense PCB layouts
- RoHS compliant and halogen-free construction
Applications
- High-speed digital interface protection
- Wireless communication modules operating at 2.4 GHz
- Portable electronic devices requiring compact EMC solutions
Procurement Notes
Verify the specific suffix T210 against the official TDK datasheet to confirm tape-and-reel specifications and packaging details. Ensure the ordering part number matches the required inductance and current ratings for your circuit design. Cross-reference the manufacturer's latest documentation for any updates on compliance certifications or material declarations before finalizing procurement orders.
Selection Notes
Select this component when space constraints require a 0403 package size while maintaining high-frequency performance up to 2.4 GHz. The 50 mA current rating suits low-power signal lines rather than power delivery paths. Consider the 2-ohm DC resistance impact on signal attenuation if driving sensitive loads. Verify that the -25°C to +85°C operating range meets the environmental requirements of the target application.
Part Context
This component belongs to the TCM-M series of thin-film common mode chokes manufactured by TDK Corporation. The series utilizes advanced thin-film deposition techniques to achieve superior high-frequency characteristics compared to traditional wound components. These filters are engineered specifically for modern electronics where miniaturization and signal integrity are critical priorities.
Replacement Considerations
Check for TCM0403S-350-2P-T210 as a potential variant within the same series. Confirm pinout compatibility and electrical equivalence before substitution. Verify that alternative parts meet the same 0403 footprint and 2.4 GHz performance criteria.
