BLP-44+

Overview

The BLP-44+ is a 50Ω coaxial low-pass filter designed for RF applications, covering a frequency range from DC to 44 MHz. It features a BNC in-line termination style and operates within a temperature range of -55°C to +100°C. The component utilizes high Q capacitors and wire-welded inductors to achieve its filtering characteristics. Key electrical specifications include a cutoff frequency of 48.5 MHz at the 1dB bandwidth point and a maximum power handling capability of 27 dBm.

Feature Summary

• Constructs filtering networks using high Q capacitors and wire-welded inductors for stable performance
• Provides in-line connectivity via BNC terminations for easy integration into test setups
• Operates reliably across an extended industrial temperature range

Applications

• Test and measurement equipment signal conditioning
• Video equipment frequency management
• Laboratory use for RF signal purification
• Defense communications systems

Procurement Notes

Verify the specific suffix requirements against the manufacturer's current datasheet before ordering. Confirm that the BLP-44+ designation matches the exact cutoff and impedance needs of your design. Ensure compatibility with existing BNC infrastructure. Check for any RoHS or REACH compliance documentation if required by your procurement policy. Validate the operating temperature range against your environmental constraints.

Selection Notes

Select this component when a sharp cutoff below 50 MHz is required in a 50Ω system. The BNC interface suits benchtop or modular rack installations where quick connection changes are necessary. Consider the 27 dBm power rating to ensure it exceeds the maximum expected signal level. Evaluate the physical size constraints of the BNC module form factor against available panel space.

Part Context

This part belongs to Mini-Circuits' BLP series of coaxial low-pass filters. The series offers various cutoff frequencies while maintaining consistent 50Ω impedance and BNC termination styles. These filters are engineered for general-purpose RF applications requiring reliable attenuation of higher frequencies.

Replacement Considerations

Consult the official Mini-Circuits substitution guide for verified alternatives. Cross-reference cutoff frequencies and impedance values carefully. Ensure mechanical compatibility with existing BNC connectors.
