BPF-C73+

Overview

The BPF-C73+ is a surface-mount bandpass filter from Mini-Circuits designed for RF signal conditioning. It operates within a frequency range of 63 MHz to 85 MHz, providing a center frequency of 73 MHz with a bandwidth of 22 MHz. The component features a 50-ohm impedance and utilizes an SMD/SMT termination type. It is housed in a 14-SMD module package with dimensions of 22.1 mm x 20.3 mm. The device supports an operating temperature range from -40°C to +85°C and complies with RoHS standards.

Feature Summary

• Surface-mount construction for automated assembly integration
• Bandpass filtering capability centered at 73 MHz
• RoHS compliant manufacturing process

Applications

• EMI/RFI suppression circuits
• Power line filtering applications
• General RF signal conditioning

Procurement Notes

Verify the specific datasheet version when ordering, as Mini-Circuits may update documentation without changing the part number. Confirm that the 14-SMD package dimensions align with your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Cross-reference the Mouser number 139-BPF-A730 if sourcing through that distributor to ensure accurate identification.

Selection Notes

Select this component when a fixed 73 MHz center frequency with a 22 MHz bandwidth is required. The 50-ohm impedance matches standard RF systems. Consider the physical size of the 14-SMD package during layout planning. Verify that the surface-mount technology suits your production capabilities. Check if the specified temperature range covers your operational environment.

Part Context

This part belongs to the Mini-Circuits BPF series of bandpass filters. It is distinct from other models like the BPF-A730+, which operates at much higher frequencies (670-795 MHz). The BPF-C73+ is specifically engineered for lower frequency applications compared to many other components in the manufacturer's portfolio.

Replacement Considerations
