TDK recommends a symmetrical PCB layout with a solid ground plane, and keeping the input and output traces as short as possible. A 4-layer PCB with a dedicated power plane and a separate ground plane is also recommended.
To ensure reliability, follow the recommended derating guidelines for temperature and power dissipation. Also, ensure good thermal conductivity between the device and the PCB, and consider using a heat sink if necessary.
The maximum allowable voltage for the HHM1589E1 is 1.5 times the rated voltage, but not exceeding 150% of the rated voltage for a maximum of 10 seconds. Prolonged exposure to high voltage can reduce the device's lifespan.
Yes, the HHM1589E1 can be used in a parallel configuration to increase the current rating, but it's essential to ensure that the devices are properly matched and that the current sharing is balanced to avoid overheating and reduce reliability.
TDK recommends storing the HHM1589E1 in a dry, cool place with a temperature range of -10°C to 30°C and a relative humidity of 60% or less. Avoid storing the devices in direct sunlight or near heat sources.
