DLW5BTZ142TQ2L - Murata Electronics

DLW5BTZ142TQ2L Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the DLW5BTZ142TQ2L?
  The recommended land pattern can be found in the Murata application note 'Ceramic Resonator Mounting Manual' (PDF). It provides detailed guidelines for PCB layout and land pattern design.
• How does the DLW5BTZ142TQ2L behave in high-temperature environments?
  While the datasheet specifies an operating temperature range of -20°C to 80°C, Murata recommends derating the resonator's frequency and stability above 60°C. For high-temperature applications, consider using a resonator with a higher temperature rating or consulting with Murata's technical support.
• Can I use the DLW5BTZ142TQ2L in a design that requires high shock and vibration resistance?
  Yes, the DLW5BTZ142TQ2L is designed to withstand moderate shock and vibration. However, for extreme environments, consider using a resonator with enhanced ruggedization, such as Murata's 'High-Reliability' series, or consult with Murata's technical support for custom solutions.
• How do I ensure the DLW5BTZ142TQ2L is properly driven and loaded in my circuit?
  Follow the recommended drive level and load capacitance guidelines in the datasheet. Additionally, consider using a buffer circuit or a dedicated oscillator IC to ensure proper drive and loading conditions.
• Are there any specific PCB material and construction recommendations for the DLW5BTZ142TQ2L?
  Use a high-quality, low-loss PCB material with a dielectric constant (εr) close to 4.5. Avoid using PCB materials with high moisture absorption or those prone to delamination. Consult with Murata's technical support for specific recommendations.
