Procurement Notes

Verify the specific capacitance value required, as the part number may correspond to either 1000pF or 1500pF variants. Confirm RoHS compliance status through official datasheets, as environmental classifications can vary by production batch. Ensure surface-mount footprint compatibility with existing PCB designs before finalizing procurement orders.

Selection Notes

Select this component when third-order attenuation is necessary for EMI/RFI suppression in space-constrained designs. The choice between 1000pF and 1500pF depends on the specific cutoff frequency requirements of the application circuit. Consider the -55°C to 125°C rating for environments with significant thermal fluctuations.
