Overview
The BPF-C45+ is a surface-mount bandpass RF filter manufactured by Mini-Circuits. It features a center frequency of 45MHz and a bandwidth of 40MHz. The component is housed in a 14-SMD module package with dimensions of 22.10mm x 20.32mm x 6.35mm. It supports an operating temperature range of -40°C to 85°C and handles a maximum RF power input of 0.5W.
Feature Summary
- Provides high signal rejection characteristics for noise suppression
- Maintains good voltage standing wave ratio (VSWR) performance
- Designed for reliable operation within specified industrial temperature ranges
Applications
- RF signal conditioning circuits
- Intermediate frequency filtering stages
- Communication system front-ends
Procurement Notes
Verify the specific ordering suffix required for your packaging needs, such as tape-and-reel or cut-tape options. Confirm RoHS3 compliance status and ensure the 14-SMD footprint matches your PCB layout. Check manufacturer documentation for exact pin configurations and thermal management requirements during integration.
Selection Notes
Select this component when a 45MHz center frequency with 40MHz bandwidth is required. Ensure the 14-SMD package size fits the available board space. Verify that the 0.5W power handling capability meets the system's signal strength requirements. Consider the -40°C to 85°C operating range against environmental conditions.
Part Context
This part belongs to the Mini-Circuits BPF series of radio frequency filters. These components are designed for general-purpose RF applications requiring precise frequency selection. The '+' suffix typically indicates lead-free and RoHS-compliant manufacturing standards consistent with current environmental regulations.
Replacement Considerations
Consult official Mini-Circuits substitution guides for verified alternatives. Cross-reference center frequency, bandwidth, and package dimensions to ensure compatibility. Do not assume functional equivalence without verifying electrical specifications against the original design requirements.
