CC7A-T1A

Product catalog summary

Product Overview: The CC7A-T1A is a quartz crystal designed for surface mount applications, utilizing a photolithographic process. It is suitable for use in implantable medical devices, optical networks, satellite communications, airborne equipment, and telemetry. The crystal is available in ultra-miniature sizes, making it ideal for implantable medical applications.

Specifications: The crystal operates in the frequency range of 24 MHz to 50 MHz with a fundamental mode. It offers high stability, low aging, and resistance to shock and vibration. The package height is 0.9 mm, with an option to add 0.75 mm. It is hermetically sealed and offers excellent solderability.

Electrical Characteristics: At 25°C, the frequency range is 24 – 50 MHz with load capacitances of 3.0, 9.0, and 16.0 pF. Frequency tolerance at +25°C is +/-50 ppm. The drive level is 100/250 µW, and insulation resistance is a minimum of 500 MΩ. Aging in the first year is a maximum of +/-3 ppm.

Environmental Characteristics: The storage temperature range is –55 to +125°C, with operating temperature ranges of –40 to +85°C (standard) and –55 to +125°C (extended). The crystal can withstand shock resistance of 5000 g and vibration resistance of 20 g from 10–2000 Hz.

Terminations and Processing: The CC7A-T1A is designed for SMD mounting with Au plated pads and can undergo reflow soldering at +260°C for a maximum of 20 seconds. An alternative version, CC7A-T3A, uses Sn/Ag/Cu plating.

Ordering Information: Unique part numbers are generated for each product specification. The crystals are available in 12mm tapes on 7" reels or in plastic trays. Standard frequencies range from 24 MHz to 50 MHz, with specific frequencies available on request.

Compliance and Quality: The product is 100% lead-free and RoHS compliant, ensuring high-quality Swiss manufacturing standards.
