BPF-B190+

Overview

The BPF-B190+ is a surface-mount lumped LC bandpass filter manufactured by Mini-Circuits. It operates within a frequency range of 185 MHz to 195 MHz with a center frequency of 190 MHz and a bandwidth of 10 MHz. The component features a 50 Ohm impedance and utilizes a 6-SMD, no-lead package style designated as HZ1198. Designed for radio frequency applications, it supports board mounting and complies with RoHS and REACH standards.

Feature Summary

• Utilizes lumped LC topology for precise bandpass filtering characteristics
• Optimized for 50 Ohm system impedance matching
• Compact surface-mount design suitable for automated assembly

Applications

• Radio frequency signal conditioning
• IF stage filtering in communication systems
• Spectrum analysis equipment input stages

Procurement Notes

Verify the specific datasheet version for exact insertion loss and return loss specifications prior to integration. Confirm that the HZ1198 package dimensions align with the target PCB footprint. Ensure compliance with RoHS3 requirements if mandated by the end-product regulations. Cross-reference the manufacturer's latest documentation for any updates to the recommended soldering profile or reflow temperature limits.

Selection Notes

Select this component when a narrow 10 MHz bandwidth centered at 190 MHz is required. The lumped LC construction offers a compact alternative to distributed line filters at these frequencies. Consider the SMD form factor for space-constrained designs requiring high reliability. Evaluate the impedance match against source and load networks to minimize reflection losses in the passband.

Part Context

This part belongs to Mini-Circuits' RF filter portfolio, which covers DC to 86 GHz. The BPF series specifically addresses bandpass needs using discrete LC elements. These components are engineered for consistent performance in commercial and industrial RF environments, providing stable filtering without the size penalties of cavity resonators.
