Procurement Notes

Verify the specific suffix TD25 against official TDK documentation to confirm packaging details such as reel or cut tape specifications. Ensure the selected variant matches the required impedance and current ratings for the target circuit design before finalizing procurement orders.

Selection Notes

Select this component when a 120 Ohm impedance at 100 MHz is required for signal integrity management. The 800 mA current rating suits moderate signal lines. The AEC-Q200 certification makes it suitable for automotive environments requiring high reliability and wide temperature operation capabilities.

Part Context

This part belongs to the TDK MMZ series of ferrite beads, which are widely used for electromagnetic interference suppression. The MMZ2012R121ATD25 specifically targets signal lines where low insertion loss and high impedance are needed to filter high-frequency noise without affecting the primary signal path.
