R0.25S-0505/H - RECOM Power

R0.25S-0505/H Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  RECOM recommends a PCB layout with a large copper area for heat dissipation, and a thermal via connection to the heat sink. A minimum of 1 oz copper thickness is recommended. Additionally, a thermal interface material (TIM) with a thermal conductivity of at least 1 W/mK should be used between the module and the heat sink.
• How do I ensure the module is properly soldered and connected?
  RECOM recommends using a soldering iron with a temperature of 350°C (662°F) and a solder with a melting point of 220°C (428°F). The module should be soldered within 3 seconds, and the solder joints should be inspected for any defects or cold joints. Additionally, the module's pins should be connected to the PCB using a secure and reliable connection method, such as soldering or wire bonding.
• What is the derating curve for the module's output power versus ambient temperature?
  RECOM provides a derating curve in the datasheet, which shows the maximum output power versus ambient temperature. The curve indicates that the module's output power should be derated by 2.5% per degree Celsius above 40°C (104°F) to ensure reliable operation and prevent overheating.
• Can I use this module in a high-vibration or high-shock environment?
  The R0.25S-0505/H module is designed to meet the requirements of IEC 60068-2-6 (vibration) and IEC 60068-2-27 (shock). However, it's recommended to consult with RECOM's application engineers to ensure the module is suitable for the specific vibration and shock requirements of your application.
• What is the recommended input capacitor value and type for this module?
  RECOM recommends using a low-ESR ceramic capacitor with a value of 10-22 μF and a voltage rating of at least 50 V. The capacitor should be placed as close as possible to the module's input pins to minimize noise and ensure stable operation.
