What are the key features of TCM1210-900-2P-T?

  • 90 Ω output impedance data-line filter in compact 1210 (3225M) SMD package for space-constrained EMI filtering
  • Dual-function design (2 circuits) with ferrite wire-wound core delivering broadband common-mode noise attenuation
  • 100 mA rated DC current with only 1.2 Ω maximum DC resistance minimizing signal path insertion loss
  • 0.6 mm ultra-low profile height enabling use in slim PCB designs including wearables and portable devices

What is TCM1210-900-2P-T used for?

The TCM1210-900-2P-T is used to suppress common-mode EMI on USB, HDMI, and serial data lines in consumer electronics, industrial sensors, and automotive infotainment systems. Its dual-circuit architecture filters two signal lines simultaneously, making it efficient for differential-pair interfaces such as USB 2.0 and CAN bus where both lines must be filtered in a single component footprint. The 90 Ω impedance characteristic is tuned to target high-frequency noise in the 100 MHz to 1 GHz range, protecting downstream ICs from conducted interference.

Frequently Asked Questions

What impedance and DC current rating does the TCM1210-900-2P-T provide for data-line filtering?

The TCM1210-900-2P-T delivers 90 Ω output impedance for effective common-mode noise attenuation while supporting up to 100 mA of DC current with a maximum DC resistance of only 1.2 Ω. This combination allows the filter to operate on active data lines such as USB 2.0 or I2C without causing excessive voltage drop or signal degradation.

Which communication interfaces benefit most from the TCM1210-900-2P-T dual-function filter topology?

Differential interfaces including USB 2.0 (480 Mbps), CAN bus (up to 1 Mbps), and RS-485 (up to 10 Mbps) benefit most, since both lines of the differential pair are filtered simultaneously by the 2-circuit design. This eliminates the need for two separate single-line chokes and reduces BOM count by 1 component while maintaining common-mode rejection on both conductors within a 3225M footprint.

How does the 0.6 mm height profile of the TCM1210-900-2P-T compare to standard inductor packages in height-critical PCB designs?

At 0.6 mm total height, the TCM1210-900-2P-T fits within the same Z-axis envelope as 0402 capacitors, making it suitable for PCB areas directly under shields or near connectors with only 1 mm clearance. Standard 1210-size wound components often stand 2 mm or taller, so TDK's 0.6 mm profile reduces assembly interference in smartphones, smartwatches, and other sub-5 mm-thin designs.

What insulation resistance specification makes the TCM1210-900-2P-T suitable for safety-isolated data interfaces?

The TCM1210-900-2P-T specifies a minimum insulation resistance of 10 MΩ between circuits, ensuring adequate isolation between the two filtered data lines and preventing leakage currents that could corrupt logic-level signals at 3.3 V or 5 V. This 10 MΩ floor also satisfies many industrial EMC pre-compliance requirements for equipment operating in environments with up to 500 V transient spikes on data cables.
