Procurement Notes

Verify the specific datasheet revision and electrical parameter tolerances against your design requirements before procurement. Confirm that the HU1186 package footprint matches your PCB layout constraints. Ensure compatibility with your assembly process for surface mount components. Cross-reference the manufacturer part number BPF-C141+ with authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when a fixed center frequency of 141 MHz with a 70 MHz bandwidth is required. The 50 Ohm impedance rating suits standard RF transmission lines. Consider the HU1186 package size for space-constrained designs. Evaluate insertion loss and rejection characteristics from the official datasheet to ensure they meet system sensitivity and interference mitigation needs.

Part Context

Mini-Circuits specializes in RF, IF, and microwave components ranging from DC to 86 GHz. The BPF series represents their line of bandpass filters engineered for signal integrity. The BPF-C141+ belongs to this family, utilizing lumped element construction to achieve specific frequency response characteristics in a small form factor suitable for modern electronics manufacturing.

Replacement Considerations

Consult Mini-Circuits documentation for direct equivalents or updated series replacements. Verify that any substitute maintains identical 110-180 MHz passband specifications and 50 Ohm impedance. Ensure physical compatibility with the HU1186 footprint if board space is limited.
