PLP-30+

Overview

The PLP-30+ is a lumped LC low-pass filter designed for radio frequency applications. It operates from DC to 32 MHz with a nominal cutoff frequency of 35 MHz. The component features a 50 Ohm impedance and utilizes an 8-DIP module package (Case Style A01). It provides signal conditioning with a rejection of 20 dB at 47 MHz. The unit supports an operating temperature range of -55°C to +100°C, ensuring reliability in various environmental conditions.

Feature Summary

• Lumped LC construction for effective low-pass filtering
• Plug-in DIP module design for easy integration
• Wide operating temperature range for industrial use

Applications

• RF signal conditioning
• IF stage filtering
• Microwave component interfacing

Procurement Notes

Verify the specific impedance requirement before ordering, as Mini-Circuits offers a 75 Ohm variant (PLP-30-75+) for different system standards. Confirm that the 8-DIP package dimensions fit the target PCB layout. Ensure the operating environment stays within the specified -55°C to +100°C range to maintain performance specifications. Cross-reference datasheet revision dates for accurate electrical parameters.

Selection Notes

Select this component when a 50 Ohm system requires low-pass filtering up to 32 MHz. The 35 MHz cutoff frequency provides a transition band suitable for rejecting higher frequency interference while passing baseband signals. Consider the physical size of the DIP-8 package during board design. This model is appropriate for general RF and IF applications where moderate selectivity is sufficient.

Part Context

Mini-Circuits manufactures a broad portfolio of RF, IF, and microwave components ranging from DC to 86 GHz. The PLP series represents their line of plug-in low-pass filters. These components are engineered for consistent performance across diverse communication systems. The company emphasizes high-quality materials and precise manufacturing tolerances for all filter products.

Replacement Considerations

The PLP-30-75+ serves as a direct functional substitute if the system requires 75 Ohm impedance instead of 50 Ohm. Verify pinout compatibility and mechanical footprint before swapping between variants. No other direct cross-references are publicly confirmed for this specific part number.
