RSF-942.500-35000-1109-TR-NS4

Overview

The RSF-942.500-35000-1109-TR-NS4 is a Surface Acoustic Wave (SAW) filter manufactured by Raltron Electronics, designed for RF applications. It operates at a center frequency of 942.5 MHz with a bandwidth of 35 MHz. The component exhibits an insertion loss of 2.1 dB and is housed in a compact 5-SMD, No Lead package with a maximum height of 0.021 inches (0.55 mm). This device is RoHS3 compliant and remains in active production status.

Feature Summary

• Utilizes Surface Acoustic Wave technology for precise RF signal filtering
• Optimized for high-frequency operation at 942.5 MHz
• Compact surface-mount design suitable for space-constrained PCB layouts

Applications

• RF front-end modules requiring bandpass filtering
• Wireless communication systems operating near 942.5 MHz
• Industrial, Scientific, and Medical (ISM) radio equipment

Procurement Notes

Verify the specific suffix NS4 against official Raltron documentation to confirm pinout and mechanical tolerances. Ensure compatibility with automated pick-and-place equipment due to the 5-SMD no-lead package profile. Cross-reference the RoHS3 compliance status with current regional regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a narrow 35 MHz bandwidth is required around the 942.5 MHz center frequency. The low 2.1 dB insertion loss makes it suitable for sensitive receiver chains. Consider the 0.55 mm height constraint for thin-profile designs. Compare performance metrics against alternative SAW filters if stricter attenuation or different form factors are needed.

Part Context

This part belongs to the RSF series of RF SAW filters from Raltron Electronics. The series typically offers various center frequencies and bandwidths tailored for specific wireless standards. The RSF-942.500 variant targets niche RF bands, distinguishing itself from broader commercial Wi-Fi or cellular filters through its specific frequency tuning and acoustic wave construction.

Replacement Considerations

Direct substitutes must match the 942.5 MHz center frequency, 35 MHz bandwidth, and 5-SMD package. Verify equivalent insertion loss and physical dimensions to ensure board compatibility. Consult manufacturer cross-reference lists for verified alternatives.
