RR111-1DC2-332 - Coto Technology

RR111-1DC2-332 Frequently Asked Questions (FAQs)

• What is the recommended PCB land pattern for the RR111-1DC2-332?
  The recommended PCB land pattern can be found in the Coto Technology application note AN-13, which provides a detailed layout and footprint recommendation for the RR111-1DC2-332.
• How do I ensure reliable switching performance in high-vibration environments?
  To ensure reliable switching performance in high-vibration environments, it is recommended to use a relay socket or a relay holder to secure the relay, and to follow proper PCB mounting and soldering techniques. Additionally, consider using a relay with a higher vibration rating, such as the RR112 series.
• What is the maximum allowable voltage drop across the relay coil?
  The maximum allowable voltage drop across the relay coil is 20% of the nominal coil voltage. For the RR111-1DC2-332, the nominal coil voltage is 5V, so the maximum allowable voltage drop is 1V.
• Can I use the RR111-1DC2-332 in a high-temperature environment?
  The RR111-1DC2-332 is rated for operation up to 85°C. For high-temperature applications, consider using a relay with a higher temperature rating, such as the RR122 series, which is rated up to 125°C.
• What is the recommended derating curve for the relay's switching current?
  The recommended derating curve for the RR111-1DC2-332's switching current can be found in the Coto Technology application note AN-11, which provides a detailed derating curve for the relay's switching current based on ambient temperature.
