Procurement Notes

Verify the specific voltage rating and tolerance requirements against your circuit design specifications before procurement. Confirm that the radial lead configuration aligns with your board layout constraints. Ensure compatibility with your assembly process regarding lead spacing and soldering temperatures. Cross-reference the manufacturer's datasheet for detailed mechanical dimensions and electrical characteristics to guarantee proper integration.

Selection Notes

Select this component when a combined resistive and capacitive filtering solution is required in a single package. The radial form factor is suitable for applications where surface mount options are insufficient or where higher mechanical stability is needed. Consider the 100 Ohm resistance value for its impact on signal attenuation and power dissipation within the target circuit environment.

Part Context

This part belongs to Meritek's EMI/RFI filter series, specifically the MEXR line. These components are designed to address electromagnetic compatibility challenges in various electronic devices. The series offers integrated solutions that simplify circuit design by combining passive filtering elements into standardized packages, reducing component count and assembly complexity.

Replacement Considerations

Check for equivalent RC networks from other manufacturers offering similar 100 Ohm and 0.1 microfarad values. Verify that any substitute maintains the same radial lead configuration and voltage rating. Ensure the replacement component meets the same environmental and reliability standards required for your application.
