BPF-A113+

Overview

The Mini-Circuits BPF-A113+ is a surface-mount bandpass filter designed for signal conditioning applications. It operates within a frequency range of 108 to 118 MHz, providing a bandwidth centered at 113 MHz. The component features a 50 Ohm impedance and utilizes SMD/SMT termination types. It is housed in an HQ1157 package with dimensions of 34.54 mm x 9.27 mm x 8.89 mm. The device supports an operating temperature range from -40°C to +85°C and includes aqueous washable options.

Feature Summary

• Utilizes lumped LC technology for precise signal filtering
• Housed in a shielded case to minimize interference
• Offers high rejection rates for out-of-band signals
• Features good voltage standing wave ratio (VSWR) performance

Applications

• Harmonic rejection in RF circuits
• Transmitter and receiver signal conditioning
• Industrial microwave and RF systems
• Telecommunication and broadband networks

Procurement Notes

Verify the specific datasheet version for the BPF-A113+ to confirm exact electrical parameters such as insertion loss and VSWR values before integration. Ensure compatibility with the target PCB footprint and thermal management requirements. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability of the component supply chain.

Selection Notes

Select the BPF-A113+ when a narrow bandpass characteristic around 113 MHz is required for 50 Ohm systems. Consider its physical dimensions and surface-mount form factor for space-constrained designs. Evaluate its operating temperature range against environmental conditions. Compare its rejection specifications with other filters in the BPF series if stricter out-of-band attenuation is needed for the specific application.

Part Context

This component belongs to the Mini-Circuits BPF series of surface-mount bandpass filters. These filters are engineered using lumped LC technology and are available in shielded cases. The series provides various VSWR options and supports both 50 Ohm and 75 Ohm impedances. They are designed for robust performance in demanding RF environments, including military and aerospace applications.

Replacement Considerations

Check for direct substitutes within the Mini-Circuits BPF series that match the 113 MHz center frequency and 50 Ohm impedance. Verify that any alternative component maintains similar physical dimensions and pinout configurations to ensure board compatibility without redesign.
