BPF-BY250+

Overview

The BPF-BY250+ is a lumped LC bandpass filter manufactured by Mini-Circuits, designed for RF applications requiring precise frequency selection. It operates within a passband of 150 MHz to 350 MHz, centered at 250 MHz with a bandwidth of 200 MHz. The component features a nominal insertion loss of 2.5 dB and maintains a standard 50 Ohm impedance across its ports. Constructed in a surface-mount package, it offers high rejection characteristics outside the designated passband. This passive filter is compliant with RoHS and REACH standards, ensuring suitability for modern electronic manufacturing requirements.

Feature Summary

• Utilizes lumped LC technology to achieve effective signal filtering with low insertion loss
• Provides high rejection capabilities to suppress out-of-band interference and harmonics
• Designed for stable performance in 50 Ohm RF systems with compact surface-mount packaging

Applications

• Test and measurement equipment requiring specific frequency band isolation
• Transmitter and receiver circuits needing harmonic rejection
• RF systems demanding reliable bandpass filtering in the 150-350 MHz range

Procurement Notes

Verify the exact datasheet version when sourcing, as Mini-Circuits may update electrical specifications or mechanical drawings over time. Confirm that the + suffix indicates compliance with current environmental regulations such as RoHS and REACH. Ensure the surface-mount footprint matches your PCB design constraints before finalizing procurement decisions.

Selection Notes

Select this component when a fixed center frequency of 250 MHz with a 200 MHz bandwidth is required. It is suitable for designs prioritizing low insertion loss and high out-of-band rejection using lumped LC topology. Consider the surface-mount package size during layout planning to ensure adequate clearance for thermal management and assembly processes.

Part Context

Mini-Circuits specializes in RF, IF, and microwave components ranging from DC to 86 GHz. The BPF-BY250+ belongs to their passive filter portfolio, which includes various technologies like LTCC and lumped LC designs. These components support signal chain functions such as filtering and impedance matching for commercial and industrial projects.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Evaluate alternative bandpass filters based on identical center frequency (250 MHz), bandwidth (200 MHz), and impedance (50 Ohm) requirements if substitution is necessary.
