Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm material composition and termination specifications. Ensure that the selected variant matches the required current rating and voltage derating guidelines for the target application environment. Cross-reference datasheet revisions to validate compliance with current environmental standards before finalizing procurement orders.

Selection Notes

Select this component when board space constraints require a feed-through topology without increasing the footprint size. Evaluate the thermal management requirements to ensure operation remains within the specified temperature range. Confirm that the 50 mA current capacity aligns with the peak load expectations of the circuit to prevent performance degradation or failure under stress conditions.
