Ultra-low Profile Tuning Fork Offers Significant Performance in Compact Package

Fox Electronics, a leading global supplier of frequency control solutions and an IDT company, has developed its most compact watch crystal, measuring just 1.6 mm x 1.1 mm x 0.5 mm (L x W x H). Although smaller in size, the new FX161 crystal operates at many of the same high standards as previous models, making it one of the most efficient tuning forks yet. The crystal’s ultra-low profile and exceptional performance optimizes the minimal space available in many portable and handheld applications, including wearable devices. The new surface mount device (SMD) operates at a frequency of 32.768 kHz. Frequency tolerance is ±20 ppm at 25°C with a long term of -0.046 ppm per Delta C2. Standard load capacitance is 12.5 pF, with optional 7 pF or 9 pF available. The new tuning fork ages only ±3 ppm in the first year, and features a termination finish of gold over nickel. Overall operating temperature range is -40°C to +85°C with a turnover temperature range of +20°C to +30°C and a storage temperature of -55°C to +125°C. Maximum soldering is 10 seconds at 260°C. The new watch crystal sustains a maximum of 90 kilo-ohms equivalent series resistance and an insulation resistance of 500 mega-ohms at 100 VDC. 

Fox Electronics is located in Fort Myers, Florida. After more than 30 years of development, Fox Electronics has become the industry's leading global supplier of a wide range of advanced frequency control solutions for a wide range of applications from wireless communications and computer to instrumentation, aerospace and more. The company is known for its forging technology pioneers, and the technological breakthroughs have changed the pattern of the frequency control industry. Recently, the company's revolutionary XpressO Series configurable oscillators provide buyers and designers with unprecedented delivery flexibility, reducing lead times and lowering costs, while delivering uncompromising electrical performance.
