OKR-T/3-W12-C - Murata Electronics

OKR-T/3-W12-C Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Murata recommends a PCB layout with a solid ground plane, minimal thermal resistance, and a heat sink attached to the module's thermal pad for optimal thermal performance.
• How do I ensure reliable start-up and shutdown of the OKR-T/3-W12-C?
  To ensure reliable start-up and shutdown, Murata recommends a soft-start circuit, a voltage supervisor, and a power-on reset circuit to prevent voltage spikes and ensure a clean power-up sequence.
• What is the maximum allowed capacitance for the output filter capacitor?
  The maximum allowed capacitance for the output filter capacitor is 47μF. Exceeding this value may cause instability or oscillation in the converter.
• Can I use the OKR-T/3-W12-C in a high-temperature environment?
  While the OKR-T/3-W12-C is rated for operation up to 85°C, Murata recommends derating the output power and ensuring good airflow to prevent overheating in high-temperature environments.
• How do I troubleshoot issues with the OKR-T/3-W12-C, such as output voltage deviations or instability?
  To troubleshoot issues, check the input voltage, output load, and PCB layout. Verify that the input voltage is within the recommended range, the output load is within the specified range, and the PCB layout meets Murata's recommendations.
