1905BP18B0050001E

Overview

The 1905BP18B0050001E is a surface-mount RF bandpass filter manufactured by Johanson Technology Inc. Designed for the 1.905 GHz frequency range, this component features a 50 MHz bandwidth and a typical insertion loss of 1.65 dB. It utilizes a 1206 (3216 metric) package with dimensions of 3.20mm x 1.60mm x 1.40mm maximum height. The device operates within a temperature range of -40°C to +85°C and supports SMD/SMT termination types.

Feature Summary

• Provides selective signal filtering in the 1.905 GHz ISM band
• Compact 1206 surface-mount ceramic construction
• Optimized for low insertion loss performance

Applications

• ISM band wireless communication modules
• Bluetooth and Zigbee transceivers
• Industrial, Scientific, and Medical (ISM) equipment

Procurement Notes

Verify the specific suffix 'E' against the manufacturer's current datasheet to confirm compliance with RoHS directives and lead-free specifications. Ensure the ordering part number matches the exact electrical requirements for the target application frequency. Cross-reference legacy part numbers if replacing older inventory versions.

Selection Notes

Select this component when a narrow 50 MHz bandwidth is required at 1.905 GHz. The 1206 footprint offers a balance between size and power handling for standard PCB layouts. Consider the 1.65 dB insertion loss impact on system link budget during design integration.

Part Context

This part belongs to Johanson Technology's line of high-frequency ceramic RF filters.
