• Strong Electrical Performance: High Q value, low ESR, frequency accuracy up to ±5ppm, pure local oscillator signal, strong anti-interference ability.
• Heat Dissipation and Mechanical Properties: Metal base has good heat dissipation, anti-vibration and anti-shock, suitable for industrial and vehicle vibration conditions.
• Wide Compatibility: Standard plug-in pins, suitable for traditional PCB through-hole technology, no need to modify the board, compatible with most radio frequency transmitting circuits.

Product Introduction

F11 SAW Resonator adopts a flat metal hermetic package structure, which is a four-pin plug-in frequency device. It is mainly used in radio frequency transmitting circuits of ISM frequency bands such as 315MHz/433.92MHz/868MHz. The standard through-hole pins are easy to weld and suitable for traditional PCB assembly technology.

With the advantages of high hermeticity and electromagnetic shielding of metal package, it has the core characteristics of high Q value, low ESR, wide temperature resistance and strong anti-interference. The frequency accuracy can generally reach ±10~±30ppm, the high-precision grade is ≤±5ppm, and the operating temperature covers -40°C~+85°C (automotive grade can reach -40°C~+125°C). It can effectively isolate moisture, impurities and electromagnetic interference, ensuring long-term frequency stability and reliability.

The product is widely used in industrial Internet of Things, automotive electronics, security smart home, high-end radio frequency and other scenarios, and can meet the diversified needs of harsh working conditions, high-precision frequency stabilization and strong anti-interference. It is a highly reliable plug-in frequency source device with both performance and compatibility.
