Crystal Units/Crystal Oscillators

Product catalog summary

Overview: The document is a technical catalog for crystal units and oscillators, detailing specifications, applications, and packaging information. It emphasizes adherence to specified ratings and cautions to prevent damage, such as smoking or burning. The catalog complies with EU RoHS standards and includes specifications that require approval before ordering.

Contents: The catalog is organized into sections for consumer, automotive, and industrial applications, each with features, dimensions, part numbers, and packaging details. It includes a selection guide, part numbering system, and measuring circuits for crystal units.

Specifications: Detailed specifications for various crystal units and oscillators are provided, including frequency ranges, dimensions, frequency tolerance, frequency shift by temperature, and aging. It also outlines equivalent series resistance (ESR), load capacitance, and drive level for each part.

Applications: Crystal units are suitable for high-accuracy applications such as GPS, Wi-Fi, Bluetooth, SATA, and USB3.0, used in smartphones, wearable devices, storage devices, and audio equipment.

Part Numbering: The catalog explains the part numbering system, which includes product ID, lead style, nominal center frequency, frequency tolerance, frequency shift by temperature, overtone order, and packaging.

Packaging: Details on packaging options, including plastic taping, are provided to ensure proper handling and storage.

Key Features: The crystal units are noted for their small package size, high accuracy, and compliance with RoHS directives. They are designed to reduce mounting area and are lead-free.

Important Notes: Users are advised to read the ratings and cautions carefully to prevent damage. The catalog contains typical specifications, and users must approve product specifications before ordering.

Procedures and Recommendations:

Soldering: Reflow soldering is recommended with specific pre-heating and peak temperature conditions. The use of rosin-based flux is advised, and water-soluble flux should be avoided.
Storage: Products should be stored in stable temperature and humidity conditions, with a shelf life of six months. Avoid chemical atmospheres and direct sunlight.
Mounting: Components should be mounted using optical placement machines to avoid mechanical damage. Conformal coating or washing is not recommended.

Standards and Compliance: The crystal units comply with RoHS and ELV directives and are lead-free. They also meet AEC-Q200 standards for automotive applications.

Applications: These crystal units are suitable for powertrain management, ADAS, chassis and safety applications, and car multimedia equipment.

Packaging: Details on reel dimensions and minimum quantities for packaging are provided, with specific instructions on cover film peel strength and speed.

Critical Notes:

Ensure circuit design provides adequate negative resistance to prevent oscillation issues.
Implement fail-safe functions to prevent secondary damage from component failure.
Avoid using these components in critical transportation applications like engine or brake control.

Mounting and Soldering Guidelines:

Reflow soldering is recommended with specific pre-heating and peak temperature conditions.
Use rosin-based flux and avoid water-soluble flux.
Do not reuse components once mounted, and avoid washing the components.

Storage and Handling:

Store in stable temperature and humidity conditions (-10°C to +40°C, 15% to 85% RH).
Use within six months of delivery to prevent degradation in solderability.
Avoid chemical atmospheres and direct sunlight during storage.

Packaging: Crystal units are packaged in plastic tape reels with specific dimensions and quantities (3,000 or 9,000 units per reel).

Additional Notes: The document emphasizes the importance of reading the ratings and cautions to prevent damage such as smoking or burning. It also highlights the need for approval of product specifications before ordering.

Ordering and Inquiries: Before placing an order, it is advised to consult with sales representatives or product engineers. For any questions, these contacts should be reached.

Product Specifications and Approval: The catalog contains typical specifications. It is necessary to approve product specifications or complete an approval sheet before ordering.

Intellectual Property Rights: The company assumes no responsibility for conflicts related to intellectual property rights unless specified. No third-party rights are granted without consent.

Environmental Compliance: The manufacturing process does not use ozone-depleting substances as per the Montreal Protocol.
