2911-05-321 Frequently Asked Questions (FAQs)

  • The recommended PCB layout and land pattern can be found in the Coto Technology application note AN-105, which provides guidelines for optimal PCB design and assembly.
  • To ensure reliable switching performance, it's recommended to use a relay socket or a relay holder to secure the relay, and to follow proper PCB mounting and screwing techniques. Additionally, consider using a relay with a higher vibration rating, such as the 2911-05-321-HV.
  • The maximum allowable voltage drop across the relay contacts is 0.5V. Exceeding this voltage drop may lead to premature contact wear or failure.
  • The 2911-05-321 is rated for operation up to 85°C. For high-temperature applications, consider using a relay with a higher temperature rating, such as the 2911-05-321-HT, which is rated up to 125°C.
  • To prevent EMI, use a shielded cable or a twisted pair cable for the relay coil, and consider adding a ferrite bead or a common-mode choke to the coil circuit. Additionally, ensure proper PCB layout and grounding techniques.
