Overview
The RSF-915.000-26000-1411-TR is a Surface Acoustic Wave (SAW) filter manufactured by Raltron Electronics, designed for general-purpose RF applications. It operates at a center frequency of 915.000 MHz with a bandwidth of 26 MHz and an insertion loss of 2.5 dB. The component utilizes a 5-SMD, no-lead package measuring 1.40 x 0.70 x 1.10 mm. It supports a maximum operating temperature of 85°C and a minimum of -40°C, suitable for ISM band applications including LoRa and SIGFOX.
Feature Summary
- Surface Acoustic Wave technology for RF signal filtering
- Compact 5-SMD no-lead surface mount package
- Optimized for ISM band frequencies
Applications
- ISM Band devices
- LoRa communication modules
- SIGFOX networks
Procurement Notes
Verify the specific ordering suffix to ensure correct packaging quantity and reel specifications. Confirm that the 5-SMD no-lead footprint matches the target PCB design. Check for any updated reflow profile requirements to prevent thermal damage during assembly. Ensure the center frequency aligns with regulatory standards for the intended region.
Selection Notes
Select this component when a narrow-band SAW filter is required for 915 MHz ISM operations. Consider the 2.5 dB insertion loss and 26 MHz bandwidth against system sensitivity requirements. Evaluate the small 1.40 x 0.70 mm footprint for space-constrained designs. Compare performance against alternative SAW filters if wider bandwidth or lower loss is necessary.
Part Context
This part belongs to Raltron's SAW Filter family, which targets industrial, scientific, and medical (ISM) radio bands. The series includes various center frequencies and bandwidth options tailored for wireless telemetry and low-power wide-area network (LPWAN) technologies. The RSF series emphasizes compact size and reliable performance in harsh environments.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs before considering alternatives.
