12LRS333C - Murata Electronics

12LRS333C Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the 12LRS333C?
  Murata recommends a land pattern with a pad size of 2.5mm x 1.5mm, with a non-solder mask defined (NSMD) pad shape, and a minimum clearance of 0.5mm between the pad and the solder mask.
• How do I handle the 12LRS333C's sensitivity to moisture?
  To prevent moisture-related issues, store the 12LRS333C in a dry environment (less than 30% RH) and follow the recommended baking procedure before reflow soldering. Also, ensure the PCB is properly cleaned and dried before assembly.
• What is the maximum reflow temperature for the 12LRS333C?
  The maximum reflow temperature for the 12LRS333C is 260°C, with a maximum dwell time of 30 seconds above 240°C. Exceeding this temperature may cause damage to the component.
• Can I use the 12LRS333C in a high-vibration environment?
  While the 12LRS333C is designed to be robust, it's still a ceramic resonator and may be susceptible to vibration-induced frequency shifts. If your application involves high vibration, consider using a more robust resonator or implementing vibration-dampening measures.
• How do I troubleshoot frequency deviations in the 12LRS333C?
  To troubleshoot frequency deviations, check the PCB layout for any issues, ensure proper termination and loading, and verify the oscillator circuit design. Also, check for any signs of mechanical stress, moisture, or contamination that may affect the resonator's performance.
