Overview
The TCM0806S-120-2P is a two-line common mode choke manufactured by TDK Corporation, designed for surface mount applications. It features an impedance of 12 Ohms and supports a maximum DC current of 100 mA. The component has a maximum DC resistance of 1 Ohm and operates within a temperature range of -40°C to +85°C. Housed in a compact 0806 metric package with dimensions of 2.0 mm x 1.6 mm x 1.0 mm, it provides effective noise suppression for high-speed data lines.
Feature Summary
- Integrated ESD protection element for enhanced signal line safety
- Compact surface mount design suitable for space-constrained PCB layouts
- High impedance performance for effective common mode noise filtering
Applications
- USB interface circuit protection
- HDMI signal line filtering
- Ethernet port noise suppression
Procurement Notes
Verify the specific suffix code against the manufacturer's latest documentation to ensure correct packaging and tape specifications. Confirm RoHS compliance status directly from the official datasheet before procurement. Ensure the ordering part number matches the required impedance and current ratings for the target application.
Selection Notes
Select this component when space constraints require an 0806 footprint with integrated ESD protection. Evaluate the 12 Ohm impedance against the target frequency spectrum to ensure adequate noise attenuation. Verify that the 100 mA current rating exceeds the maximum operating current of the protected data line to prevent saturation.
Part Context
This component belongs to the TCM-S series of common mode chokes from TDK Corporation. The series is engineered for protecting high-speed digital interfaces from electromagnetic interference and electrostatic discharge events. It serves as a critical passive component in modern electronic devices requiring robust signal integrity.
Replacement Considerations
Consult TDK official documentation for verified substitute part numbers. Cross-reference impedance values and physical dimensions to ensure compatibility with existing PCB footprints and circuit requirements.
