Fort Myers, FL – Fox Electronics 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 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 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 watch crystal sustains a maximum of 90 kilo-ohms equivalent series resistance and an insulation resistance of 500 mega-ohms at 100 VDC. The ultra-low profile FX161 watch crystal comes in a standard tape and reel containing 3,000 pieces and is RoHS compliant.
