SF3-DC24V Frequently Asked Questions (FAQs)

  • The maximum switching frequency of the SF3-DC24V relay is 20 Hz. However, it's recommended to limit the switching frequency to 10 Hz or less to ensure reliable operation and minimize wear on the relay.
  • The SF3-DC24V relay is rated for operation up to 85°C. However, it's recommended to derate the relay's current handling capability by 1.5% for every degree above 70°C to ensure reliable operation.
  • The SF3-DC24V relay requires a minimum load current of 10 mA to ensure reliable operation. Operating the relay with a load current below this threshold may result in unreliable switching or failure.
  • The SF3-DC24V relay is designed to withstand vibrations up to 10 G (10-55 Hz). However, it's recommended to secure the relay properly to prevent damage or malfunction due to excessive vibration.
  • The recommended PCB layout and spacing for the SF3-DC24V relay can be found in the Panasonic application note AN13111. It's essential to follow these guidelines to ensure reliable operation and minimize electromagnetic interference (EMI).
