VLF-190+

Overview

The VLF-190+ is a low-pass filter manufactured by Mini-Circuits, designed for signal conditioning applications. It operates within a frequency range of 0 Hz to 190 MHz and features a characteristic impedance of 50 Ohms. The component utilizes an SMA in-line module package with chassis mounting capabilities. Constructed using LTCC technology, it provides reliable performance for RF and microwave circuits requiring precise frequency filtering.

Feature Summary

• LTCC construction for stable high-frequency performance
• SMA connector interface for easy integration
• Chassis mount design for robust installation

Applications

• RF signal conditioning systems
• Microwave circuit filtering
• Communication equipment frequency management

Procurement Notes

Verify the specific datasheet version to confirm mechanical dimensions and electrical tolerances before procurement. Ensure compatibility with existing SMA connectors and chassis mounting hardware. Confirm RoHS compliance status if required by project specifications. Cross-reference part numbers to avoid confusion with similar models in the VLF series.

Selection Notes

Select this component when a 190 MHz cutoff frequency is required in a 50-Ohm system. The SMA interface suits applications needing standard coaxial connections. Consider the chassis mount form factor for permanent installations rather than board-level surface mount solutions. Verify thermal requirements against the operating temperature range specified in the official documentation.

Part Context

This component belongs to the VLF series of low-pass filters from Mini-Circuits. The series offers various cutoff frequencies while maintaining consistent 50-Ohm impedance and SMA connectivity. These filters are engineered for general-purpose RF applications where reliable attenuation of higher frequencies is necessary without significant insertion loss in the passband.

Replacement Considerations

Consult the official Mini-Circuits substitution guide for verified alternatives. Ensure any substitute maintains the 190 MHz cutoff and 50-Ohm impedance. Verify that the replacement also uses SMA connectors and compatible mounting styles to ensure mechanical fit.
