GMOV-14D950K - Bourns

GMOV-14D950K Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for the GMOV-14D950K?
  Bourns provides a recommended PCB layout and land pattern in their application note AN164, which can be found on their website. It's essential to follow these guidelines to ensure proper mounting and to minimize thermal resistance.
• How do I select the correct fuse holder or clip for the GMOV-14D950K?
  Bourns offers a range of fuse holders and clips compatible with the GMOV-14D950K. Engineers should consult the Bourns website or contact their local distributor to determine the correct part number based on their specific application requirements.
• What is the maximum operating temperature range for the GMOV-14D950K?
  While the datasheet specifies an operating temperature range of -40°C to 85°C, it's essential to note that the fuse's performance and reliability may be affected at extreme temperatures. Engineers should consider derating the fuse's current rating at high temperatures to ensure safe operation.
• Can I use the GMOV-14D950K in a high-vibration or high-shock environment?
  The GMOV-14D950K is designed to meet standard vibration and shock requirements. However, for extreme environments, engineers should consult Bourns' application notes and consider additional mounting or securing methods to ensure the fuse remains securely in place.
• How do I determine the correct fuse current rating for my application?
  Engineers should calculate the maximum current that the circuit can supply, considering factors like inrush current, steady-state current, and fault current. The fuse current rating should be selected based on the maximum current calculated, ensuring a safe margin to prevent nuisance tripping.
