AWCR-12.00MD - ABRACON

AWCR-12.00MD Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for AWCR-12.00MD?
  Abracon recommends a land pattern with a pad size of 1.3mm x 0.8mm, with a non-solder mask defined (NSMD) pad and a keep-out area of 0.5mm around the pad.
• Can AWCR-12.00MD be used in high-temperature applications?
  Yes, AWCR-12.00MD is rated for operation up to 125°C, making it suitable for high-temperature applications. However, the crystal's frequency stability and aging characteristics may be affected at extreme temperatures.
• How do I ensure the crystal oscillator starts reliably in my design?
  To ensure reliable startup, Abracon recommends using a load capacitor with a value between 12pF and 22pF, and a series resistor with a value between 1kΩ and 10kΩ. Additionally, the oscillator circuit should be designed to provide a stable power supply and minimize noise.
• Is AWCR-12.00MD compatible with lead-free soldering processes?
  Yes, AWCR-12.00MD is compatible with lead-free soldering processes, including RoHS and WEEE directives. However, the recommended soldering temperature profile should be followed to prevent damage to the crystal.
• What is the typical frequency tolerance of AWCR-12.00MD?
  The typical frequency tolerance of AWCR-12.00MD is ±20 ppm at 25°C, with a maximum tolerance of ±50 ppm over the operating temperature range.
