4000BP15U1800001E

Overview

The 4000BP15U1800001E is a surface-mount bandpass RF filter manufactured by Johanson Technology Inc. It features a center frequency of 4GHz and a bandwidth of 1.8GHz, with an insertion loss of 2.3dB. The component is housed in a compact 0805 (2012 metric) package, measuring 2.00mm x 1.25mm x 0.80mm maximum height. Designed for signal conditioning, it utilizes LGA terminations to reduce PCB area usage. The device is RoHS3 compliant and operates within standard commercial temperature ranges.

Feature Summary

• High rejection bandpass filtering characteristics
• LGA termination design for reduced PCB footprint
• Compact 0805 surface mount form factor

Applications

• Ultra-wideband (UWB) signal conditioning
• RF front-end interference suppression
• Wireless communication systems requiring 4GHz band filtering

Procurement Notes

Verify the complete part number including suffixes against official Johanson Technology documentation to ensure correct packaging and specifications. Confirm RoHS3 compliance status if required by specific regulatory standards. Check for any recent global part numbering changes that may affect ordering codes or availability through authorized distributors.

Selection Notes

Select this component when a narrow bandpass response centered at 4GHz is required in a minimal space constraint. The 0805 package suits high-density layouts where LGA terminations offer mechanical stability and electrical performance advantages over traditional leaded packages. Ensure the 1.8GHz bandwidth aligns with the specific application's spectral requirements.

Part Context

This component belongs to Johanson Technology's integrated passive components portfolio, specifically designed for RF applications.
