Overview
The TCM0403S-350-2P-T210 is a two-channel common mode filter choke manufactured by TDK Corporation. It features an impedance of 35 Ohms at 100 MHz and an inductance of 49 nH. The component supports a maximum DC current of 50 mA with a maximum DC resistance of 3.9 Ohms. Designed for surface mount installation, it operates within a temperature range of -25°C to +85°C. Its compact physical dimensions are 0.45 mm in length, 0.3 mm in width, and 0.25 mm in height.
Feature Summary
- Thin-film construction designed for wide frequency range applications
- Optimized for high-speed differential signal interfaces
- Ultra-small footprint suitable for dense PCB layouts
Applications
- High-speed differential signal line filtering
- Common mode noise suppression in ultra-high-speed data lines
- Signal integrity protection in compact electronic devices
Procurement Notes
Verify the complete part number including the suffix T210 to ensure correct packaging configuration. Confirm that the 50 mA current rating meets the specific circuit requirements. Check RoHS compliance status through official manufacturer documentation before integration into regulated products.
Selection Notes
Select this component when space constraints require a sub-millimeter height profile. Ensure the operating environment stays within the specified -25°C to +85°C range. Verify that the 35 Ohm impedance at 100 MHz aligns with the target noise frequencies for effective common mode rejection.
Part Context
This component belongs to the TCM-S series of thin-film common mode filters from TDK. These components utilize advanced thin-film technology to achieve superior performance in high-frequency applications compared to traditional wound chokes.
Replacement Considerations
Consult official TDK documentation for verified equivalent part numbers. Do not substitute with generic components without confirming impedance curves and physical dimension compatibility.
