Procurement Notes

Verify the specific suffix 'JS' against official manufacturer documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with RoHS3 standards if required by your application. Cross-reference datasheet parameters such as DCR and current ratings before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a 27 µH inductance in a compact SMD footprint. Consider the 120 mA current limit and 6.9 Ohm resistance when designing power-sensitive RF circuits. Compare against shielded alternatives if electromagnetic interference suppression is critical for the system.
