SF2735K

Overview

The SF2735K is a Surface Acoustic Wave (SAW) filter manufactured by RFMi, designed for signal conditioning applications. It operates at a center frequency of 925 MHz with an insertion loss of 3.5 dB and a nominal impedance of 50 Ohms. The device functions within a frequency range of 1156 to 1196 MHz and requires 0 VDC bias. It is housed in a compact surface-mount package measuring 5.0 x 5.0 x 1.7 mm. The component complies with RoHS directives and supports soldering profiles up to 260°C peak temperature.

Procurement Notes

Verify the specific datasheet version from RFMi or authorized distributors to confirm current manufacturing status and pinout configurations. Ensure compatibility with existing PCB layout dimensions, specifically the 5.0 x 5.0 mm footprint. Confirm that the operating temperature range meets the environmental requirements of the final assembly, noting the -40°C minimum limit.

Selection Notes

Select this component when a compact SAW filter is required for 925 MHz applications with low insertion loss characteristics. Consider the 5.0 x 5.0 mm SMD package size for space-constrained designs. Verify that the 50 Ohm impedance matches the surrounding circuitry. Evaluate thermal management capabilities against the specified soldering temperature limits during assembly.
