LPF-B50+

Overview

The LPF-B50+ 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 50 MHz and features a nominal impedance of 50 ohms. The component utilizes surface-mount technology (SMT) and is housed in a shielded package with dimensions of 12 mm x 21 mm x 5.6 mm. It supports SMD/SMT termination types and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Shielded surface-mount construction for electromagnetic interference protection
• Lumped LC topology optimized for low-frequency signal filtering
• Standard 50-ohm impedance compatibility for RF system integration

Applications

• RF signal conditioning circuits
• Low-pass filtering in communication systems
• Baseband signal processing stages

Procurement Notes

Verify the exact datasheet version corresponding to the specific manufacturing lot, as Mini-Circuits may update mechanical drawings or electrical tolerances over time. Confirm that the shielded package dimensions match your PCB footprint requirements precisely. Ensure the operating temperature range meets your environmental specifications before finalizing procurement orders.

Selection Notes

Select this component when a compact, shielded low-pass filter is required for frequencies up to 50 MHz. The lumped LC design offers a balance between performance and size for baseband applications. Consider the 50-ohm impedance standard for seamless integration into existing RF test equipment or communication modules requiring minimal insertion loss.

Part Context

This part belongs to the LPF series of low-pass filters from Mini-Circuits, which are widely used in RF and microwave engineering. The series provides various cutoff frequencies to suit different bandwidth requirements. The LPF-B50+ specifically targets lower frequency ranges compared to higher-frequency variants in the same product family.

Replacement Considerations

Check for direct substitutes such as the LPF-B0R8+ for lower frequency needs or LPF-B500+ for higher bandwidths. Verify pinout compatibility and impedance matching when replacing components in existing designs to ensure circuit stability.
