RF3336D

Overview

The Murata Electronics RF3336D is a Surface Acoustic Wave (SAW) bandpass filter designed for narrowband receiver front-end applications. It operates at a center frequency of 868.35 MHz with a bandwidth of 650 kHz. The device features an insertion loss of 2.7 dB and supports voltage ratings up to 12 V. Impedance values are specified as 35.6 Ohms and 35.8 Ohms. It utilizes an SM-3838-8 surface-mount package and is qualified under AEC-Q200 standards. The component functions within a temperature range of -40°C to +125°C.

Procurement Notes

Verify current product status, as sources indicate this model may be obsolete or discontinued. Confirm availability through authorized distributors and check for official discontinuation notifications. Ensure the required package type and impedance specifications match the target design requirements before procurement.

Selection Notes

Select this component for designs requiring a 650 kHz bandwidth at 868.35 MHz. Consider the 2.7 dB insertion loss impact on system sensitivity. Verify compatibility with the SM-3838-8 footprint and ensure the operating environment stays within the -40°C to +125°C range. Check for alternative sources if original manufacturing has ceased.

Part Context

This SAW filter belongs to Murata's line of signal conditioning components for RF applications. It is part of a series of filters targeting European ISM bands. The device integrates coupled resonator technology to achieve sharp roll-off characteristics necessary for interference rejection in crowded spectral environments.
