PLP-2.5+

Overview

The PLP-2.5+ is a lumped LC low-pass filter designed for RF applications with a cutoff frequency of 2.75 MHz and a passband extending from DC to 2.5 MHz. It operates within a standard 50Ω impedance environment and utilizes an 8-DIP through-hole package, specifically the A01 case style. The component supports a wide operating temperature range from -55°C to +100°C, ensuring stability in demanding environments. Key electrical characteristics include a return loss ranging from 0.47dB to 33.53dB, providing effective signal integrity maintenance across its specified bandwidth.

Feature Summary

• Lumped LC architecture provides compact filtering performance
• Through-hole 8-DIP packaging facilitates easy integration
• Wide operational temperature tolerance for industrial use

Applications

• RF signal conditioning circuits
• Industrial measurement and control systems
• Wireless communication baseband interfaces

Procurement Notes

Verify the specific suffix (+) indicates the standard commercial grade version when sourcing. Confirm the 8-DIP pinout matches the target PCB footprint before assembly. Ensure the 50Ω system impedance aligns with the surrounding circuit design to maintain optimal return loss performance. Check the manufacturer's latest datasheet for any updates on environmental ratings or material compliance documentation prior to final procurement.

Selection Notes

Select this component when a sharp low-pass response is required below 3 MHz with high power handling capabilities typical of lumped element designs. The through-hole format is preferred over surface mount options for applications requiring mechanical robustness or manual assembly processes. Consider the thermal range if the device will operate in extreme ambient conditions without active cooling.

Part Context

This part belongs to Mini-Circuits' extensive portfolio of passive RF filters, specifically the PLP series which focuses on low-frequency applications. Unlike high-frequency microwave components, these filters utilize discrete LC topologies rather than transmission line structures. They serve as fundamental building blocks for anti-aliasing and noise suppression in analog front-end stages.

Replacement Considerations

Consult official Mini-Circuits substitution guides for direct equivalents. Verify that any alternative maintains the same 50Ω impedance and 8-DIP form factor to ensure mechanical compatibility.
