R1SE-3.305/H2-R - RECOM Power

R1SE-3.305/H2-R Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  RECOM recommends a PCB layout with a large copper area for heat dissipation, and a minimum of 2oz copper thickness. A thermal via array under the module can also improve heat transfer.
• How do I ensure the module's reliability in high-temperature environments?
  To ensure reliability, RECOM recommends operating the module within the specified temperature range (-40°C to +85°C). Additionally, consider derating the output power and using a heat sink or thermal interface material to reduce thermal stress.
• What are the EMI filtering requirements for this module?
  The R1SE-3.305/H2-R module has built-in EMI filtering, but additional external filtering may be required depending on the application and regulatory requirements. RECOM recommends following the guidelines in the datasheet and consulting with a qualified EMI expert if necessary.
• Can I use this module in a redundant or parallel configuration?
  Yes, the R1SE-3.305/H2-R module can be used in redundant or parallel configurations, but RECOM recommends consulting with a qualified engineer to ensure proper design and implementation to avoid potential issues with synchronization, current sharing, and fault tolerance.
• What is the recommended input capacitance for this module?
  RECOM recommends using a low-ESR input capacitor with a minimum capacitance of 10uF to ensure stable operation and minimize input ripple. The capacitor should be rated for the input voltage and have a low equivalent series resistance (ESR).
