BFHK-6251+

Overview

The BFHK-6251+ is a miniature low temperature co-fired ceramic (LTCC) band pass filter designed for high repeatability and performance consistency. It features a passband ranging from 5350 to 6700 MHz with a center frequency of approximately 6.1 GHz. The component operates at a nominal impedance of 50 Ohms and exhibits an insertion loss of 4.5 dB. Packaged in a compact 3-SMD, no-lead surface mount format measuring 4.5mm by 3.2mm, it supports high layout density while minimizing parasitic effects.

Feature Summary

• Utilizes proprietary LTCC material system for miniature size and high performance repeatability
• Provides ultra-high stopband rejection characteristics
• Surface mountable design suitable for very high frequency applications
• Small footprint allows for high circuit board layout density

Applications

• Wireless communication systems requiring signal conditioning
• RF front-end modules needing bandpass filtering
• High-density electronic circuit boards

Procurement Notes

Verify the exact part number suffix against official Mini-Circuits documentation to ensure correct specifications. Confirm that the LTCC construction and SMD package dimensions match your PCB layout requirements. Check for any specific handling instructions related to the surface mount technology used in this component.

Selection Notes

Select this component when a compact band pass filter with a 5.35 to 6.7 GHz range is required. Consider its 4.5 mm x 3.2 mm footprint for space-constrained designs. Ensure compatibility with 50 Ohm system impedance and verify that the 4.5 dB insertion loss meets system budget constraints.

Part Context

This component belongs to the BFHK series of LTCC band pass filters from Mini-Circuits. These filters are engineered for applications demanding small form factors and reliable RF performance. The series utilizes advanced ceramic materials to achieve consistent electrical characteristics across production batches.

Replacement Considerations

Consult Mini-Circuits official substitution guides for verified alternatives. Ensure any replacement maintains the same LTCC construction, 50 Ohm impedance, and compatible SMD package dimensions.
