GMOV-14D450K - Bourns

GMOV-14D450K Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the GMOV-14D450K?
  Bourns recommends a symmetrical PCB layout with a ground plane underneath the device to minimize parasitic inductance and ensure optimal performance. A minimum of 2 oz copper thickness is recommended for the PCB.
• How do I select the correct MOV for my specific application?
  To select the correct MOV, consider factors such as the maximum voltage rating, surge current rating, and energy absorption capability required for your application. Consult Bourns' selection guide or contact their technical support for assistance.
• What is the derating curve for the GMOV-14D450K at high temperatures?
  Bourns provides a derating curve in the datasheet, which shows the maximum allowable voltage and current ratings at elevated temperatures. For example, at 125°C, the device is derated to 80% of its nominal voltage rating.
• Can I use the GMOV-14D450K in a DC-powered circuit?
  Yes, the GMOV-14D450K can be used in DC-powered circuits. However, it's essential to ensure that the DC voltage does not exceed the device's maximum voltage rating, and that the circuit is designed to handle the device's leakage current.
• How does the GMOV-14D450K respond to repetitive surges?
  The GMOV-14D450K is designed to withstand repetitive surges within its specified ratings. However, the device's lifespan may be affected by the frequency and magnitude of the surges. Consult Bourns' application notes for guidance on surge withstand capability.
