TCM1210G-900-2P-T200

Overview

The TCM1210G-900-2P-T200 is a surface-mount common mode filter designed for high-speed differential signal lines. It features two lines with an impedance of 90 Ohms at 100 MHz and a maximum DC resistance of 1.2 Ohms. The component has a current rating of 100 mA and a DC voltage rating of 10 V. Its physical dimensions are 1.25 mm in length, 1.00 mm in width, and a maximum height of 0.67 mm, housed in a 0504 (1210 metric) package with four leads.

Feature Summary

• Designed specifically for filtering high-speed differential signal lines
• Surface mount construction for automated assembly integration

Applications

• High-speed data interface protection
• Differential signal line noise suppression

Procurement Notes

Verify the specific suffix T200 against official TDK documentation to confirm tape and reel specifications. Confirm that the 1.2 Ohm DCR limit aligns with your circuit requirements. Check for end-of-life status as some distributors list this model as discontinued. Ensure compatibility with your PCB footprint dimensions of 1.25mm x 1.00mm.

Selection Notes

Select this component when managing differential pairs requiring 90 Ohm impedance matching at 100 MHz. The low DCR supports signals with current demands up to 100 mA. The compact 1210 metric footprint suits space-constrained designs. Verify thermal performance under continuous operation conditions.
