Description
The YXC YSR433S321 is a high-performance, 1-port Surface Acoustic Wave (SAW) resonator designed specifically for stable frequency control in wireless applications. Operating at the widely used ISM band frequency of 433.92 MHz, this component functions as a passive band-pass filter, leveraging the piezoelectric effect in crystalline materials to convert electrical signals into acoustic waves for precise filtering and resonance.
Housed in a 4-pad SMD package, this SAW resonator is ideal for compact wireless modules. It is a critical component in remote-control security systems, garage door openers, telemetry hardware, and short-range radio transceivers, where maintaining a stable carrier frequency is essential to ensuring reliable communication and signal integrity.
