3314H-1-503 Frequently Asked Questions (FAQs)

  • Bourns recommends a symmetrical PCB layout with a solid ground plane, and keeping the input and output traces as short as possible to minimize noise and EMI.
  • The 3314H-1-503 has built-in overvoltage protection (OVP) and overcurrent protection (OCP) circuits that will limit the output voltage and current to prevent damage to the device and downstream components.
  • Bourns recommends using a 10uF to 22uF ceramic or film capacitor with a voltage rating of at least 50V, placed as close as possible to the input pins of the device.
  • The 3314H-1-503 is rated for operation up to 125°C, but derating may be necessary for high-temperature applications. Consult the datasheet and Bourns' application notes for more information.
  • The 3314H-1-503 has a soft-start feature that ramps up the output voltage during power-up, and a shutdown pin that can be used to control the power-down sequence. Consult the datasheet for more information.
