SF2250E

Overview

The SF2250E is a Surface Acoustic Wave (SAW) filter manufactured by Murata Electronics, designed for general-purpose RF applications. It operates at a center frequency of 1.615 GHz with a bandwidth of 20 MHz and an insertion loss of 3.4 dB. The component features a 50-ohm impedance and utilizes a compact 6-SMD, No Lead package (SM-3030-6). It supports voltage ratings up to 3 V and functions within a temperature range of -20°C to +70°C.

Feature Summary

• Utilizes Surface Acoustic Wave technology for precise RF signal filtering
• Optimized for high-frequency operation at 1.615 GHz
• Compact surface-mount design suitable for space-constrained layouts

Applications

• General purpose RF filtering in wireless communication devices
• Signal conditioning in mobile handset architectures
• Frequency selection in transceiver modules

Procurement Notes

Verify the specific suffix and package variant against the official Murata datasheet before ordering. Confirm that the 6-SMD No Lead form factor matches your PCB footprint requirements. Ensure the operating temperature range meets your system's environmental specifications. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a SAW filter is required for 1.615 GHz applications with moderate bandwidth needs. Consider the 3 VDC rating and thermal limits during circuit design. Evaluate the 6-SMD package dimensions against available board space. Compare insertion loss characteristics against alternative filters to ensure signal integrity compliance.

Part Context

The SF2250E belongs to Murata’s portfolio of RF SAW filters, which are engineered for stable performance in consumer electronics and telecommunications. These components typically replace discrete LC networks to reduce size and improve consistency. The device integrates acoustic wave propagation mechanisms to achieve sharp frequency selectivity without active power consumption.
