Procurement Notes

Verify the specific manufacturer designation when sourcing, as this component is produced by Chilisin under license for Pulse Electronics. Confirm RoHS compliance status through official documentation prior to integration. Ensure the ordering suffix matches the required packaging format, such as cut tape or reel, to align with automated assembly processes.

Selection Notes

Select this component for applications requiring 260 Ohms impedance at 100 MHz. The 300 mA current rating suits low-power data lines. Verify that the 2.0 x 1.2 mm footprint fits the design constraints. Consider the unshielded nature if strict isolation from external fields is not required.
