LPF-B35+

Overview

The LPF-B35+ is a low-pass filter from Mini-Circuits designed for signal conditioning applications. It operates within a frequency range of DC to 35 MHz and features a cutoff frequency of 40 MHz. The component maintains a standard impedance of 50 Ohms and utilizes surface-mount technology (SMT) in a shielded package measuring 0.472 inches by 0.826 inches by 0.22 inches. Key electrical specifications include a bandwidth of 2 dB and rejection of 20 dB at frequencies between 45-2500 MHz. It supports a power handling capacity of 1 W with a VSWR of 1.5:1.

Feature Summary

• Shielded SMT construction for reliable RF performance
• Low-pass filtering capability up to 35 MHz
• High rejection characteristics above the passband

Applications

• RF signal conditioning
• Wireless communication systems
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix (+) indicates lead-free compliance as per Mini-Circuits standards. Confirm package dimensions and pin configuration match the design layout. Ensure the operating environment stays within specified thermal limits. Cross-reference the part number with official distributor catalogs to avoid counterfeit components. Validate that the 50 Ohm impedance aligns with system requirements.

Selection Notes

Select this component when a sharp cutoff near 35 MHz is required for low-frequency RF signals. Consider the shielded package for noise immunity in sensitive circuits. Evaluate the 1 W power handling against maximum signal levels. Compare insertion loss and VSWR specifications with alternative filters. Ensure the SMT footprint fits the available PCB space.
