SAW Resonators | D11 Compact Metal Package

Core Advantages

• Hermetic Metal Package: High hermeticity isolates moisture and impurities, anti-aging and long lifespan; metal housing shields EMI interference, ensuring strong radio frequency stability.
• Wide Temperature and High Reliability: Supports -40°C to +125°C wide temperature range, excellent temperature coefficient, minimal frequency drift, suitable for industrial and automotive extreme environments.
• 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

D11 SAW Resonator is a small flat metal hermetic package three-pin plug-in frequency device, mainly for 315MHz/433.92MHz/868MHz and other general ISM frequency bands. It adopts through-hole pin design, compact structure, easy installation, and can be directly compatible with traditional plug-in circuit design.

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.

Alternative Products and Reasons

Replacement Reason: Mainstream manufacturers at home and abroad basically do not mass-produce products with this package for plug-in series, only some domestic brand manufacturers are making products with this package.
