R-78B3.3-1.0 Frequently Asked Questions (FAQs)

  • The maximum input voltage is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
  • The R-78B3.3-1.0 is rated for operation up to 85°C, but derating is required above 70°C. Consult the datasheet for specific derating curves.
  • Use a 10uF ceramic capacitor between VIN and GND, and a 10uF ceramic capacitor between VOUT and GND, as close to the module as possible.
  • A minimum of 10uF input capacitance is recommended to ensure stable operation, but larger values may be required depending on the input voltage and current.
  • No, the R-78B3.3-1.0 is not designed for parallel operation. Instead, consider using a higher-current version of the module or a different product.
