DHN-04-T-V - Diptronics

DHN-04-T-V Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  Diptronics recommends a minimum of 1 oz copper thickness and a thermal relief pattern under the relay module to ensure efficient heat dissipation. A minimum clearance of 0.5 mm around the module is also recommended.
• How do I ensure reliable switching and minimize contact bounce?
  To minimize contact bounce, Diptronics recommends using a debouncing circuit or a capacitor in parallel with the coil to reduce voltage spikes. Additionally, ensure the relay is driven with a clean, regulated voltage source.
• What is the maximum allowable voltage drop across the relay contacts?
  The maximum allowable voltage drop across the relay contacts is 100 mV. Exceeding this value may lead to premature contact wear or failure.
• Can I use the DHN-04-T-V in a high-vibration or high-shock environment?
  While the DHN-04-T-V is designed to withstand moderate vibrations, it's essential to ensure the relay is properly secured to the PCB and the PCB is rigidly mounted to the chassis. Diptronics recommends consulting with their application engineers for custom vibration and shock testing.
• What is the recommended storage and handling procedure for the DHN-04-T-V?
  Store the DHN-04-T-V in its original packaging, away from direct sunlight, moisture, and extreme temperatures. Handle the relay by the edges to prevent electrostatic discharge (ESD) damage.
