Overview
The TCM1210G-301-2P-T200 is a surface-mount common mode filter designed for high-speed differential signal lines. It features two lines with an impedance of 300 Ohms at 100 MHz and a maximum DC resistance of 3.5 Ohms. The component has a rated current of 50 mA and operates within a temperature range of -25°C to 85°C. Its physical dimensions are 1.25 mm in length, 1.00 mm in width, and 0.67 mm in height, housed in a 0504 (1210 Metric) package with four leads.
Feature Summary
- Designed specifically for filtering common mode noise on high-speed differential signal lines
- Compact surface mount construction suitable for space-constrained PCB layouts
- Provides effective electromagnetic interference suppression in data transmission applications
Applications
- High-speed USB interfaces
- Differential data communication buses
- Portable electronic devices requiring EMI reduction
Procurement Notes
Verify the part status as obsolete before procurement planning. Confirm that the 3.5 Ohm DCR specification meets circuit requirements. Ensure compatibility with the 0504 footprint during design finalization. Check for RoHS3 compliance documentation if required by specific regulatory standards.
Selection Notes
Select this component when differential line protection is required for signals operating at frequencies around 100 MHz. The 50 mA current rating limits suitability to low-power data lines rather than power delivery paths. Consider the small 1210 metric package size for dense board designs where larger chokes cannot fit.
Part Context
This component belongs to the TDK TCM-G series of common mode filters. The series offers various impedance values and current ratings tailored for different signal integrity needs. The TCM1210G variant specifically targets compact form factors while maintaining performance for digital signal protection in consumer electronics.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and impedance characteristics if considering alternative manufacturers' components.
