MCZ2010AH121T

Common Mode Chokes Overview

The TDK MCZ2010AH121T is a four-line surface mount common mode choke designed for signal line filtering. It operates with an impedance of 120 Ohms at 100 MHz and supports a maximum DC current of 100 mA. The component features a maximum DC resistance of 2 Ohms and functions within a temperature range of -40°C to +85°C. Housed in a 0805 (2012 metric) package measuring 2.0 mm by 1.25 mm, it provides effective noise suppression for high-speed differential lines.

Common Mode Chokes Feature Summary

• Surface mount design for compact PCB integration
• High-frequency noise suppression capability

Common Mode Chokes Applications

• Signal line filtering
• High-speed differential circuit protection
• Common-mode noise suppression

Common Mode Chokes Procurement Notes

Verify the specific package dimensions and lead configuration against the official datasheet before procurement. Confirm that the 100 mA current rating aligns with the target application's operational requirements. Ensure compatibility with standard SMT assembly processes for the 0805 footprint.

Common Mode Chokes Selection Notes

Select this component when four independent channels require simultaneous noise filtering in a limited space. The 120 Ohm impedance at 100 MHz suits applications targeting higher frequency interference. Consider the 2 Ohm DCR limit to ensure minimal voltage drop across the filtered lines during operation.

Common Mode Chokes Part Context

This part belongs to the MCZ series of common mode chokes from TDK Corporation. It is specifically engineered for suppressing electromagnetic interference in digital signal paths.
