FORT MYERS, Fla., May 27, 2015 /PRNewswire/ -- 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 degrees 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 degrees C to +85 degrees C with a turnover temperature range of +20 degrees C to +30 degrees C and a storage temperature of -55 degrees C to +125 degrees C. Maximum soldering is 10 seconds at 260 degrees 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.

The ultra-low profile FX161 watch crystal comes in a standard tape and reel containing 3,000 pieces and is RoHS compliant.

Technical Specifications:

Ultra-low profile: 0.5 mm high
Frequency of 32.768 kHz
Long term stability
SMD tuning fork crystal
Standard tape-and-reel for easy assembly

Pricing for an FX161 tuning fork crystal depends on quantity ordered. Delivery is stock to eight weeks ARO.
