SXBP-425+

Overview

The SXBP-425+ is a lumped LC band pass filter designed for radio frequency applications. It operates with a center frequency of 425 MHz and provides a bandwidth of 30 MHz, covering the range from 410 to 440 MHz. The component features an insertion loss of 5 dB and is engineered for use in 50 Ohm systems. It utilizes an 8-SMD, no lead surface mount package, facilitating integration into compact circuit designs requiring precise signal filtering.

Feature Summary

• Lumped LC construction for stable band pass performance
• Surface mount SMD package for automated assembly
• Designed for 50 Ohm system impedance matching

Applications

• RF signal conditioning in communication equipment
• Frequency selection in receiver front-ends
• Signal filtering in test and measurement instruments

Procurement Notes

Verify the specific manufacturer datasheet for the SXBP-425+ to confirm current electrical specifications and mechanical dimensions. Ensure compatibility with your PCB footprint and soldering profile. Confirm that the component meets all required environmental standards for your intended deployment environment before finalizing procurement decisions.

Selection Notes

Select this component when a narrow band pass characteristic around 425 MHz is required. The 30 MHz bandwidth suits applications needing rejection of adjacent channel interference. Consider the 5 dB insertion loss impact on system noise figure. The SMD form factor is suitable for high-density board layouts where space constraints limit the use of larger through-hole or coaxial filters.
