RSF-868.300-7000-3030-TR

Overview

The RSF-868.300-7000-3030-TR is a Surface Acoustic Wave (SAW) filter manufactured by Raltron Electronics, designed for RF signal processing applications. It operates at a center frequency of 868.3 MHz with a bandwidth of 7 MHz. The component features an insertion loss of 2.5 dB and is optimized for 50 Ohm systems. It is housed in a compact 6-SMD, No Lead package, specifically the 1212 [3030 Metric] footprint, suitable for surface mount assembly. The device is rated for operation within a temperature range of -40°C to +85°C and is supplied in Tape & Reel packaging.

Feature Summary

• Utilizes Surface Acoustic Wave technology for precise RF filtering
• Optimized for 50 Ohm impedance matching in RF circuits
• Compact 6-pin SMD package design for space-constrained layouts

Applications

• ISM band communication modules operating at 868 MHz
• RF front-end filtering in wireless transceivers
• Signal conditioning in industrial telemetry systems

Procurement Notes

Verify the complete part number including the trailing TR suffix to confirm tape and reel packaging configuration. Ensure compatibility with the specified 1212 [3030 Metric] land pattern on the PCB layout. Confirm that the operating environment remains within the documented -40°C to +85°C temperature range to maintain specified electrical performance characteristics.

Selection Notes

Select this component when a narrowband SAW filter is required for the 868.3 MHz ISM band. The 7 MHz bandwidth provides sufficient selectivity for standard modulation schemes in this frequency range. Consider the low insertion loss of 2.5 dB for efficient power transmission. The small form factor makes it suitable for high-density board designs where larger ceramic filters would not fit.

Part Context

This component belongs to the RSF series of SAW filters from Raltron Electronics. The series offers various center frequencies tailored for global ISM bands. The RSF-868.300-7000-3030-TR specifically targets European and Asian ISM allocations around 868 MHz. It serves as a passive linear component essential for spectral purity in modern wireless devices.

Replacement Considerations

Direct substitutes must match the 868.3 MHz center frequency, 7 MHz bandwidth, and 6-pin 1212 package. Verify pinout compatibility before substitution. Cross-reference with other manufacturers offering SAW filters for the 868 MHz band, ensuring identical electrical parameters and thermal ratings are maintained.
