Procurement Notes

Verify the specific ordering suffix and packaging configuration, such as Reel or Cut Tape, against the manufacturer's latest documentation before procurement. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary. Ensure that the selected variant matches the required impedance tolerance and current rating specifications for the target application design.

Selection Notes

Select this component when a 70 Ohm impedance at 100 MHz is required for EMI suppression in space-constrained designs. The 1812 package offers a balance between current handling capability and footprint size. Consider the 800 mA current rating and 400 mOhm DC resistance to ensure minimal signal attenuation and power loss in the intended circuit path while maintaining thermal stability across the specified operating temperature range.
