PM25RG1A120 - Mitsubishi

PM25RG1A120 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Mitsubishi Electric recommends a PCB layout with a large copper area on the bottom layer to act as a heat sink, and to place thermal vias under the module to improve heat dissipation.
• How do I ensure reliable operation in high-humidity environments?
  To ensure reliable operation in high-humidity environments, it is recommended to apply a conformal coating to the module, and to follow proper storage and handling procedures to prevent moisture absorption.
• What is the maximum allowable voltage deviation for the input voltage?
  The maximum allowable voltage deviation for the input voltage is ±10% of the rated input voltage. Exceeding this deviation may affect the module's performance and reliability.
• Can I use this module in a parallel configuration to increase the output power?
  Yes, the PM25RG1A120 can be used in a parallel configuration to increase the output power. However, it is recommended to consult with Mitsubishi Electric's application engineers to ensure proper design and implementation.
• What is the recommended input filter configuration to minimize electromagnetic interference (EMI)?
  Mitsubishi Electric recommends using a pi-filter configuration with a common-mode choke and X-capacitors to minimize EMI. The specific component values and layout should be optimized based on the system's requirements and operating conditions.
