Procurement Notes

Verify the complete part number including suffixes against official Pulse Electronics documentation to ensure correct specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to procurement. Ensure that the ordering quantity aligns with available packaging formats such as cut tape or reel sizes specified in the latest datasheet. Cross-reference the manufacturer part number with distributor catalogs to avoid substitution errors.

Selection Notes

Select this component when a specific bandpass response is required for the 2.4 GHz spectrum in space-constrained designs. The 2012 package offers a balance between performance and footprint size compared to larger packages. Consider the thermal operating range if the application involves high ambient temperatures. Verify insertion loss and rejection characteristics against system requirements using the official electrical parameters table.

Part Context

This component belongs to Pulse Electronics' portfolio of RF filters designed for wireless connectivity applications. The 'BPF' designation indicates a BandPass Filter, while '2012' refers to the case size. The suffix '2400' typically denotes the center frequency or target band. These components are integral to maintaining signal integrity in crowded RF environments by attenuating out-of-band interference.

Replacement Considerations

Consult official distributor databases for direct substitutes such as the BPF2012LRPJR2400L or BPF2012LRPGR2400L from Pulse Electronics. Verify pinout compatibility and electrical performance equivalence before substituting. Ensure any replacement part meets the same package dimensions and thermal ratings.
