Crystal Unit Case

Crystal Unit Case refers to the physical enclosure or package in which a crystal unit is housed. In the context of the supply class Oscillators And Piezoelectric Crystals in the supply group Electrical And Electronic Equipment Components, Crystal Unit Case refers to the various types of cases or packages available for crystal units used in electronic devices.

Crystal units are electronic components that utilize the piezoelectric effect of certain crystals to generate precise electrical signals. These signals are commonly used in electronic devices for timekeeping, frequency control, and synchronization purposes.

The Crystal Unit Case is designed to protect the crystal unit and provide electrical connections for its integration into electronic circuits. The case may vary in size, shape, and material depending on the specific application and requirements of the crystal unit.

Some common types of Crystal Unit Cases include:

1. Metal Cans: These are typically made of metal, such as stainless steel or aluminum, and provide a robust and shielded enclosure for the crystal unit.

2. Ceramic Packages: These are made of ceramic material and offer good thermal stability and electrical insulation properties.

3. Plastic Packages: These are made of plastic materials, such as epoxy or polypropylene, and are often used for low-cost and lightweight applications.

4. Surface Mount Packages: These are designed for surface mount technology (SMT) and allow for easy integration onto printed circuit boards (PCBs).

The choice of Crystal Unit Case depends on factors such as the required frequency stability, temperature range, mechanical robustness, and cost considerations. It is important to select the appropriate case to ensure the reliable operation of the crystal unit in the intended application.
