SCLF-190+

Overview

The SCLF-190+ is a surface-mount low-pass filter from Mini-Circuits, designed for signal conditioning applications. It operates within a frequency range of 0 Hz to 190 MHz and features a 50 Ohm impedance. The component utilizes an SMD/SMT termination type and is housed in an 8-SMD, flat lead package with dimensions of 8.89 mm x 8.89 mm x 2.54 mm. It supports board mounting and functions reliably between -40°C and +85°C. Key electrical specifications include an insertion loss of 0.95 dB. The device is part of the RLP series and is available in cut tape or reel packaging formats.

Feature Summary

• Provides effective low-pass filtering for RF signals up to 190 MHz
• Designed for surface-mount technology (SMT) integration
• Maintains 50 Ohm system impedance for standard RF compatibility

Applications

• RF signal conditioning circuits
• Harmonic suppression in communication systems
• Interference filtering in receiver front-ends

Procurement Notes

Verify the exact datasheet version for the SCLF-190+ to confirm current electrical tolerances and mechanical drawings. Ensure that the selected packaging format, such as cut tape or reel, aligns with your assembly line requirements. Cross-reference the manufacturer's part number with distributor listings to confirm availability and authenticity before finalizing procurement plans.

Selection Notes

Select the SCLF-190+ when a compact, surface-mount solution is required for low-pass filtering below 190 MHz. Its 50 Ohm impedance makes it suitable for standard RF systems. Consider its physical dimensions and operating temperature range to ensure compatibility with your PCB layout and environmental conditions. Verify that the insertion loss meets your specific signal integrity requirements.

Part Context

This component belongs to Mini-Circuits' portfolio of passive RF filters. The SCLF series typically offers robust performance in a small form factor. As a low-pass filter, it is engineered to pass frequencies below the cutoff while attenuating higher frequencies. The '+' suffix generally indicates RoHS compliance in Mini-Circuits nomenclature.

Replacement Considerations

Consult official Mini-Circuits documentation for direct cross-references. Alternative low-pass filters from other manufacturers may require impedance and frequency response verification.
