Summary of FA-238/FA-238V/TSX-3225 MHz Range Crystal Units

Seiko Epson Corporation introduces the FA-238/FA-238V/TSX-3225 MHz Range Crystal Units, catering to a frequency range from 12 MHz to 50 MHz. These units are designed to be fundamental in overtone order and find applications in mobile phones, Bluetooth devices, W-LAN, ISM band radios, and as clock sources for microprocessor units (MPUs).

Product Specifications

The crystal units are compact with an external size of 3.2 x 2.5 x 0.6 mm (FA-238/FA-238V) and 3.2 x 2.5 x 0.7 mm (TSX-3225). They exhibit varying specifications with frequency tolerances as tight as ±10-6 and support a range of load capacitances from 7 pF to specified. Moreover, the products are characterized by their frequency versus temperature characteristics, with a motional resistance (ESR) that varies depending on the frequency as outlined in the provided tables. Storage temperatures range from -40°C to +125°C, while operating temperature spans -40°C to +85°C or to +105°C depending on the model.

Notably, the FA-238 units for over 40 MHz and TSX-3225 12 MHz to 48 MHz indicate a yearly frequency aging specification of ±2 x 10-6/year maximum, showcasing a stable frequency over time.

Environmental and Quality Commitments

Seiko Epson pledges to adhere to environmental standards with an ISO 14001-certified management system and continuously strive for quality improvement by meeting ISO 9001 and IATF 16949 standards for excellence in product reliability.
