Overview
The TCM1210-301-2P-T is a surface-mount common mode filter designed for high-speed differential signal lines. It features a 300 Ω impedance at 100 MHz and supports a maximum DC current of 100 mA. The component has a maximum DC resistance of 2.5 Ω and operates within a temperature range of -40°C to +85°C. Packaged in a compact 0404 (1210 metric) footprint, it provides effective noise suppression for sensitive data interfaces.
Feature Summary
- Dual-line configuration for differential signal integrity
- High impedance rating for effective common-mode noise attenuation
- Compact surface-mount design suitable for space-constrained PCBs
Applications
- High-speed USB interface noise suppression
- HDMI signal line filtering
- LVDS display interface protection
Procurement Notes
Verify the specific suffix against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging specifications. Ensure the component meets the required AEC-Q200 reliability standards if used in automotive applications. Cross-reference the impedance value at the target frequency with system requirements before procurement.
Selection Notes
Select this component when differential signal lines require common-mode noise reduction without significant insertion loss impact on the differential mode. The 100 mA current rating suits low-power digital interfaces. Consider the 1210 package size for board layout constraints and thermal management requirements relative to adjacent components.
Part Context
This part belongs to TDK's TCM series of chip common mode chokes. These components are engineered specifically for suppressing electromagnetic interference in high-speed data transmission lines. The series offers various impedance values and current ratings to match different interface standards and signal speeds.
Replacement Considerations
Check for direct substitutes such as the TCM1210-900-2P-T for higher impedance needs or other TDK TCM series variants with matching 1210 footprints and similar current ratings.
