Precautions for using Kyocera crystal oscillators

Regardless of whether it's in the field of communications, automotive systems, or other high-tech areas, Kyocera's crystal oscillator products can provide customized solutions that meet the precision and reliability requirements of specific application scenarios. Kyocera's crystal products, including crystal resonators, clock oscillators (SPXO), voltage-controlled crystal oscillators (VCXO), and temperature-compensated crystal oscillators (TCXO), cater to the needs of various application scenarios.

To ensure the performance and reliability of Kyocera's crystal oscillators, please follow these guiding principles when using them:

1.Shock and Impact Protection Measures:

Severe external forces may cause the crystal to crack or otherwise damage, affecting the functionality of the device. During the transportation, assembly, and use of the crystal oscillator, avoid any actions that may cause severe vibrations or impacts to protect it from damage. If it is inevitably exposed to shocks and vibrations beyond the specified range, the performance indicators of the crystal oscillator should be re-tested before use.

2.Prudent Cleaning Strategy:

Before considering ultrasonic cleaning for Kyocera crystal oscillators, thorough confirmation must be made, as the vibrations of ultrasonic cleaning can sometimes damage the crystal. This step is crucial to avoid potential harm.

3.Precise Soldering Specifications:

Strict soldering processes are the foundation for ensuring the long-term reliability and stability of the product. Following the manufacturer's instructions can minimize adverse effects on the crystal oscillator during the soldering process.

4.Careful Mounting Techniques:

The surface mounting technique requires precision and caution to avoid damage caused by board deformation. After mounting, if it is necessary to separate the components, or during the execution of automatic mounting processes, pay close attention to suppress impacts on the crystal oscillator. At the same time, surface-mounted crystal oscillators are not suitable for wave soldering techniques.

5.Appropriate Storage Conditions:

The storage environment of the crystal oscillator has a significant impact on its performance. Crystal oscillators should be stored in an environment with controlled temperature and humidity, with ideal conditions being a temperature between -5°C and +40°C, and relative humidity maintained at 40-60%RH. In addition, the storage time should not exceed six months.

Avoid using crystal oscillators in environments beyond the specifications, including extreme vibration or impact conditions. Also, ensure that the crystal oscillator is not directly exposed to water, saltwater, dew, or toxic gases.

6.Comprehensive Design and Application Planning:

When designing the clock crystal oscillator circuit, including ESD (Electrostatic Discharge) protection measures for CMOS integrated circuits is fundamental to ensuring the long-term stable operation of the circuit. Ensure that bypass capacitors are reasonably laid out between power and ground to protect the crystal oscillator from excessive voltage and current damage. Also, pay attention to not reverse the pins to avoid internal damage caused by reverse voltage.

For specific crystal oscillator series, such as KC7050S, strict moisture-proof management is required, and it should be installed quickly in a dry environment after opening.

Considering that some crystal oscillator series may be sensitive to sunlight or LED light, design should consider shading measures to avoid frequency fluctuations.

By careful management and operation, the performance of Kyocera's crystal oscillators can be maximized while extending their service life.
