RF3319E

Overview

The RF3319E is a surface-acoustic-wave (SAW) filter manufactured by Murata Electronics, designed for front-end selectivity in 868.95 MHz receivers. It operates within a frequency range of 868.8 MHz to 869.1 MHz with a bandwidth of 900 kHz. The component features an insertion loss of 2.4 dB and supports a voltage rating of 12 V. Impedance values are specified at 84.13 Ohms and 180.84 Ohms. It utilizes SMD/SMT termination and is housed in an SM-3030-6 package. The device meets AEC-Q200 qualification standards and functions between -40°C and +125°C.

Procurement Notes

Verify the current product status as sources indicate this part may be obsolete. Confirm availability through authorized distributors or Murata directly. Ensure the specific suffix matches required specifications. Check for valid replacement components if discontinuation is confirmed. Validate packaging quantities against current supply chain constraints.

Selection Notes

Select this component for applications requiring precise filtering at 868.95 MHz. Consider the 900 kHz bandwidth and 2.4 dB insertion loss for signal integrity requirements. The SM-3030-6 package size dictates board layout constraints. Verify thermal performance within the -40°C to +125°C operating range for the intended environment.

Part Context

The RF3319E belongs to Murata's SAW filter series, specifically engineered for European ISM band applications around 868 MHz. It serves as a critical passive component in radio frequency front-ends, offering high selectivity and low insertion loss compared to alternative filter technologies.

Replacement Considerations

The RF3319D is documented as a similar low-loss SAW filter for 868.95 MHz receivers. Verify pin compatibility and electrical parameters before substitution.
