Procurement Notes

Verify the specific ordering suffix and packaging format against official distributor catalogs before purchase. Confirm RoHS compliance status through the manufacturer's latest documentation. Ensure the selected reel or cut tape quantity matches production requirements. Cross-reference the part number with the most recent datasheet to confirm terminal type and impedance specifications remain unchanged.

Selection Notes

Select this component when a 31 Ohm impedance at 100 MHz is required for EMI suppression. The 800 mA current rating suits moderate power applications. The 1206 footprint allows for standard PCB layouts. Consider the shielded design if electromagnetic interference isolation is critical. Verify thermal performance within the specified -55 C to +125 C operating range for the target environment.
