BPF-C550+

Overview

The BPF-C550+ is a lumped LC band pass filter designed for radio frequency applications. It features a center frequency of 550MHz with a bandwidth of 900MHz, covering the range from 100 to 1000 MHz. The component operates at a nominal impedance of 50Ω and exhibits an insertion loss of 2.2dB. It is housed in a compact 14-SMD module package measuring 22.10mm x 20.32mm x 6.35mm. This surface-mount device utilizes SMT technology and is available in tape and reel packaging.

Feature Summary

• Ultra-wide bandpass filtering capability within the 100 to 1000 MHz spectrum
• Shielded surface-mount construction for reliable RF performance
• Lumped LC circuit design optimized for 50Ω systems

Applications

• RF signal conditioning in communication systems
• Interference suppression in wideband receiver front-ends
• Test and measurement equipment requiring specific band rejection

Procurement Notes

Verify the complete part number including any ordering suffixes against the manufacturer's official documentation to ensure correct specifications. Confirm that the required packaging format matches your assembly line capabilities. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure compatibility with standard surface-mount reflow profiles during procurement planning.

Selection Notes

Select this component when a fixed center frequency of 550MHz with a broad 900MHz bandwidth is required. The 50Ω impedance rating must match the system interface. Consider the physical dimensions of the 14-SMD package for PCB layout constraints. Evaluate the 2.2dB insertion loss against system sensitivity requirements before finalizing the design choice.

Part Context

Mini-Circuits manufactures a comprehensive range of RF and microwave components. The BPF series includes various bandpass filters utilizing different technologies. The BPF-C550+ represents a specific lumped LC implementation designed for general-purpose RF filtering tasks where moderate selectivity and wide bandwidth are prioritized over sharp cutoff characteristics.

Replacement Considerations

Consult Mini-Circuits official substitution guides for verified alternatives. Cross-reference electrical parameters such as center frequency, bandwidth, and insertion loss when evaluating potential substitutes. Ensure mechanical footprint compatibility if direct board replacement is intended.
