R433MHz F11 surface acoustic wave (SAW) resonator-oscillator 433.92 MHz

Description

The R433 F11 is a Surface Acoustic Wave (SAW) resonator designed to provide a stable 433.92 MHz frequency for wireless transmitters, such as remote controls and alarms.

Key Specifications

Pin Configuration (F-11 Package)

The F-11 package uses a standard 4-pin layout :

• Pin 1 & 4: Input / Output – The active terminals for the resonator.

• Pin 2 & 3: Case Ground – Connected to the metal housing for shielding.

Design Notes

• Application: This resonator is specifically designed for transmitter or local oscillator circuits in the 433.92 MHz band . It is a one-port device, meaning the input and output share the same terminals .

• Stability: It provides quartz-level frequency stability using SAW technology, which is more stable than simple LC oscillators .

• Handling: As an electrostatic-sensitive device (ESD), standard precautions should be taken during assembly
