Procurement Notes

Verify the specific suffix CT000 against official TDK documentation to confirm reel packaging and quantity specifications. Ensure the requested impedance value matches the design requirements for the target signal line. Confirm RoHS compliance status through the manufacturer's latest certification documents before finalizing procurement orders.

Selection Notes

Select this component when signal line noise suppression is required in ultra-compact layouts. The 22 Ohm impedance at 100 MHz provides effective attenuation for specific high-frequency interference. The 250 mA current rating must be sufficient for the operating conditions of the protected circuit. Consider the 01005 footprint constraints during PCB layout planning.
