TCM1210H-900-2P

Overview

The TCM1210H-900-2P is a two-channel common mode choke coil designed for signal line applications. It features an impedance of 90 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 100 mA. The component has a maximum DC resistance of 850 milliohms and operates within a temperature range of -25°C to +85°C. Housed in a compact 0504 (1210 metric) surface-mount package with four leads, it measures 1.25 mm in length, 1.00 mm in width, and up to 0.67 mm in height.

Feature Summary

• Provides common mode noise suppression for high-speed differential signal lines
• Compact surface-mount design suitable for space-constrained PCB layouts
• Unshielded construction optimized for general signal integrity

Applications

• High-speed data interface protection
• Signal line filtering in consumer electronics
• Noise suppression for peripheral connections

Procurement Notes

Verify the specific suffix designation when sourcing, as variants such as TCM1210H-900-2P-T000 exist with identical core electrical parameters but different packaging configurations. Confirm that the required operating temperature range aligns with the standard -25°C to +85°C specification. Ensure the selected variant meets the necessary RoHS compliance requirements for the intended manufacturing process.

Selection Notes

Select this component for applications requiring moderate common mode attenuation at 100 MHz with low insertion loss due to minimal DC resistance. The 100 mA current rating limits suitability to low-power signal lines rather than power distribution. Consider the unshielded nature if strict EMI isolation is critical, and verify that the 0504 footprint fits the target board design constraints.

Part Context

This part belongs to the TCM-H series of common mode chokes from TDK Corporation. The series focuses on small form-factor solutions for signal line noise reduction. The TCM1210H-900-2P specifically utilizes the 1210 metric package size, balancing physical footprint with electrical performance for modern electronic assemblies.
