Overview
The TCM0403M-900-2P-T210 is a shielded common mode filter choke designed for high-speed differential signal lines. It features a compact surface-mount package with dimensions of 0.45 mm length, 0.3 mm width, and 0.23 mm height. The component has a maximum DC resistance of 3 Ohms and a rated current of 35 mA. It operates within a temperature range of -25°C to +85°C and provides an impedance magnitude of 90 Ohms at 100 MHz.
Feature Summary
- Shielded construction minimizes electromagnetic interference coupling
- Optimized for high-speed differential signal line applications
- Ultra-low profile surface mount design facilitates dense PCB layouts
Applications
- High-speed data interface protection
- Differential signal line filtering
- Portable electronic device EMC mitigation
Procurement Notes
Verify the complete part number including suffixes against official TDK documentation to ensure correct impedance and tolerance specifications. Confirm that the required operating temperature range aligns with the specified -25°C to +85°C limits. Ensure PCB footprint compatibility with the 0.45 x 0.3 mm package dimensions prior to procurement.
Selection Notes
Select this component when space constraints require an ultra-thin form factor for signal integrity management. The 3 Ohm DC resistance and 35 mA current rating suit low-power digital interfaces. Verify that the 90 Ohm impedance at 100 MHz meets the specific noise suppression requirements of the target differential pair.
Part Context
This component belongs to the TCM-M series of common mode chokes from TDK Corporation. The series focuses on providing effective noise suppression in minimal footprints suitable for modern miniaturized electronics. It serves as a specialized passive component for maintaining signal quality in high-frequency circuits.
Replacement Considerations
Consult official TDK substitution guides for verified equivalents. Cross-referencing requires matching impedance characteristics, physical dimensions, and current ratings to ensure functional parity without redesigning the circuit layout.
