DLW5BTZ251TQ2L - Murata Electronics

DLW5BTZ251TQ2L Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the DLW5BTZ251TQ2L?
  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 DLW5BTZ251TQ2L 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 DLW5BTZ251TQ2L in a design that requires a specific impedance?
  The DLW5BTZ251TQ2L has a nominal impedance of 100 ohms. If your design requires a different impedance, you may need to add external components to match the impedance. Consult with Murata's technical support or a qualified RF engineer for guidance.
• How do I ensure the DLW5BTZ251TQ2L is properly driven and loaded?
  To ensure proper operation, the resonator should be driven with a CMOS-compatible signal and loaded with a suitable impedance. A general guideline is to use a load capacitance of 10-20 pF and a drive signal with a rise/fall time of 10-20 ns. Consult the Murata application note 'Ceramic Resonator Application Manual' (PDF) for more information.
• What are the reliability and durability expectations for the DLW5BTZ251TQ2L?
  Murata's ceramic resonators are designed to meet high reliability standards. The DLW5BTZ251TQ2L is rated for a minimum of 1,000 hours of operation at 85°C with a failure rate of 1% or less. For more information, consult Murata's reliability report or contact their technical support.
