HE1aN-AC24V Frequently Asked Questions (FAQs)
Panasonic recommends a PCB layout with a large ground plane and a separate power plane for the relay coil to minimize electromagnetic interference. Additionally, keep the relay away from high-frequency components and ensure a minimum of 1.5 mm clearance around the relay for proper heat dissipation.
To handle high inrush currents, Panasonic recommends using a soft-start circuit or an NTC thermistor in series with the load to limit the inrush current. Additionally, ensure the relay is properly derated for the expected inrush current and that the PCB is designed to handle the high current.
While the datasheet specifies an operating temperature range of -40°C to 85°C, Panasonic recommends derating the relay's performance at extreme temperatures. For reliable operation, it's recommended to operate the relay within a temperature range of 0°C to 70°C.
Yes, the HE1AN-AC24V is designed to withstand vibrations up to 10 G (10-55 Hz) and 5 G (55-2000 Hz) according to IEC 60068-2-6. However, it's recommended to ensure the relay is properly secured to the PCB and that the PCB is designed to withstand the expected vibration levels.
To prevent relay contact welding, Panasonic recommends using a snubber circuit or an RC circuit in parallel with the load to reduce the voltage spike when the relay turns off. Additionally, ensure the relay is properly derated for the expected load current and that the PCB is designed to handle the expected voltage and current.
