Electromagnet overheating?

Hi CrossRoads

Most interesting parts:

  • Enclosed design
  • completely encapsulated
  • fully encapsulated data for 100% duty
  • limit temperature: 130 ° C.

Coil data:

Relative duty cycle (percent)                   100    50    25    10
Maximum duty cycle (seconds)                    ?      -     -     -
Max Power (Watts) at 20 ° C coil temperature     2.5

I also asked the questions at All about circuits.

I'm afraid the conclusion is:
It's heatsinking, lowering the duty cycle (using PWM), adding a resistor, or just making sure the surrounding parts can handle the heat.
