Description
The YXC R433 is a high-performance Surface Acoustic Wave (SAW) resonator operating at a center frequency of 433.92 MHz. Designed specifically for frequency stabilization in transmitter circuits, this resonator utilizes the piezoelectric effect to provide a precise and stable reference frequency for wireless control systems.
As a passive band-pass filter, the R433 ensures that transmitted signals remain strictly within the required frequency band, minimizing interference and maximizing communication range. It is an industry-standard choice for demanding applications such as garage door openers, remote keyless entry (RKE) systems, and security transmitters, where signal integrity and reliability are paramount.
Key Features
- Frequency Precision: 433.92 MHz nominal frequency specifically tuned for standard ISM band wireless communication.
- Signal Stabilization: Acts as a highly effective band-pass filter to lock transmit frequencies in oscillator circuits.
- Robust TO-39 Packaging: Durable 3-pin metal can package provides excellent shielding and environmental protection.
- Passive Operation: Reliable, maintenance-free performance as a transducer-type component.
Application
- Garage Door Openers
- Security and Alarm Transmitters
- Remote Keyless Entry (RKE) Systems
- Wireless Data Links (Low-Power)
- General RF Remote Control Applications
