R-78CK3.3-0.5 Frequently Asked Questions (FAQs)

  • RECOM recommends a star-point connection for the input capacitors and a wide, solid copper pour for the output voltage to minimize EMI and ensure stable operation.
  • While the R-78CK3.3-0.5 is rated for operation up to 85°C, RECOM recommends derating the output current by 2.5% per degree above 60°C to ensure reliable operation in high-temperature environments.
  • RECOM recommends using a soldering iron with a temperature of 250°C to 270°C and a soldering time of 3 to 5 seconds per pin to prevent damage to the module.
  • The typical efficiency of the R-78CK3.3-0.5 is around 95% at full load, but this can vary depending on the input voltage, output current, and operating temperature.
  • Yes, the R-78CK3.3-0.5 can be used in a redundant or parallel configuration, but RECOM recommends consulting with their application engineers to ensure proper design and implementation.
