Procurement Notes

Verify the specific ordering suffix to ensure compliance with required packaging configurations such as cut tape or reel options. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure that the selected variant matches the precise 0402 footprint requirements for the target PCB layout. Cross-reference the datasheet specifications against system voltage and power constraints to guarantee operational reliability under all expected environmental conditions.

Selection Notes

Select this component when a zero-ohm equivalent connection is required at high frequencies without introducing significant signal reflection. The low VSWR specification ensures minimal signal loss in sensitive RF paths. Consider the ceramic material properties for applications requiring stable performance across wide temperature variations. Verify that the 100 mW power rating aligns with the maximum expected current flow in the specific circuit branch to prevent thermal degradation during continuous operation.
