SRFBF-1BJ1J-GPBA

Overview

SRFBF-1BJ1J-GPBA is a ceramic bandpass filter manufactured by Suntsu Electronics, Inc. It operates with a center frequency of 1.58 GHz and features a bandwidth of 60 MHz at 50 Ohms impedance. The component utilizes an LTCC process and is housed in a miniature 5-SMD, no lead package measuring 1.10x0.90mm. It supports an operational temperature range of -40°C to 85°C.

Feature Summary

• Utilizes Low-Temperature Co-fired Ceramic (LTCC) technology for compact integration
• Designed with a miniature footprint to conserve board space
• Engineered for low insertion loss performance

Applications

• GPS signal processing circuits
• Wireless communication modules
• RF front-end filtering applications

Procurement Notes

Verify the specific electrical characteristics against the official datasheet to ensure compliance with operational temperature ranges (-40°C to 85°C). Confirm that the 50 Ohm impedance and 1.58 GHz center frequency align with your circuit design requirements before procurement.

Selection Notes

Select this component when a small form factor is required for RF filtering. The LTCC construction offers reliability for surface mount assembly. Ensure the 60 MHz bandwidth meets the system's spectral requirements.

Part Context

This part belongs to Suntsu Electronics' line of ceramic filters. It is distinct from their crystal oscillators and other passive components, specifically designed for high-frequency signal conditioning in compact electronic devices.

Replacement Considerations

Check for compatible LTCC bandpass filters with identical 1.58 GHz center frequency and 60 MHz bandwidth. Verify pinout compatibility for the 5-SMD no-lead package and similar insertion loss specifications.
