Overview
The WTCF2012Z0M670PB is a two-line common mode choke from the WTCF2012 series, manufactured by Walsin Technology Corporation. It features a surface mount package in the 0805 (2012 Metric) form factor with dimensions of 2.0mm x 1.25mm. The component provides an impedance of 67 Ohms at 100 MHz and supports a current rating of 400mA. It has a DC resistance of 250mOhm and operates within a temperature range of -40°C to 125°C.
Feature Summary
- Provides effective noise suppression for signal lines through high impedance characteristics at target frequencies.
- Designed for compact surface mount integration in space-constrained electronic assemblies.
- Constructed as a two-line filter suitable for differential or dual-signal applications.
Applications
- Signal line filtering in portable consumer electronics
- Noise suppression in data transmission interfaces
- EMI reduction in compact circuit boards
Procurement Notes
Verify the specific impedance tolerance and current rating requirements against the official datasheet before procurement. Confirm that the 0805 footprint matches the design layout. Ensure the operating temperature range meets the environmental conditions of the final assembly. Check for RoHS compliance status if required by project specifications.
Selection Notes
Select this component when a low-profile, two-line common mode choke is needed for high-frequency noise attenuation. The 67 Ohm impedance at 100 MHz makes it suitable for specific signal integrity applications. Consider the 400mA current limit and 250mOhm DCR for power budget calculations. The 0805 size offers a balance between performance and board space efficiency.
Part Context
