LPF-B500+

Overview

The LPF-B500+ is a lumped LC low-pass filter manufactured by Mini-Circuits, designed for signal conditioning applications. It operates within a frequency range of DC to 500 MHz and features a nominal system impedance of 50 ohms. The device utilizes an SMD/SMT termination type and is housed in a compact 6-SMD, no-lead package. Key electrical specifications include a cutoff frequency of 515 MHz, a bandwidth of 2 dB, and a maximum voltage standing wave ratio (VSWR) of 1.3:1. It supports a power handling capacity of 1.25 W and provides rejection of 20 dB at frequencies between 585 MHz and 4500 MHz.

Feature Summary

• Provides effective low-pass filtering with high rejection characteristics for frequencies above the cutoff point.
• Utilizes lumped LC architecture for stable performance in signal conditioning circuits.
• Features a compact surface-mount design suitable for automated assembly processes.

Applications

• RF signal conditioning in communication systems
• Harmonic suppression in transmitter outputs
• Interference filtering in test and measurement equipment

Procurement Notes

Verify the specific datasheet version for the LPF-B500+ to confirm exact mechanical dimensions and thermal ratings. Ensure compatibility with standard 50-ohm PCB trace widths. Check for RoHS compliance status as indicated on the manufacturer's official documentation before finalizing procurement orders.

Selection Notes

Select this component when a low-pass filter with a cutoff near 500 MHz is required. Consider the 1.25 W power rating for signal levels. The 6-SMD package requires appropriate footprint verification in the PCB layout. Compare insertion loss and VSWR against system requirements to ensure signal integrity is maintained.

Part Context

This part belongs to the LPF series of low-pass filters from Mini-Circuits. These components are engineered for RF and microwave applications requiring precise frequency selection. The series offers various cutoff frequencies to suit different bandpass or lowpass filtering needs in modern electronic designs.

Replacement Considerations

Consult Mini-Circuits official substitution guides for direct equivalents. Verify that any alternative maintains the same 50-ohm impedance and similar cutoff frequency characteristics to ensure circuit compatibility without redesign.
