Operating temperature range
-40℃ – +120℃ (including temperature rise of core)
・No Ozone Layer Depleting Chemicals are used in these products or in their manufacturing process.
* Note 1: The temperature rise in the above table is a projected value based on temperature rise by the heat of the coil when the rated current (DC or 50/60Hz) in
the table below is conducted.
* Note 2: The temperature rise is affected by the mounting condition on the circuit board and the amount of harmonic distortion on the load current. Please make
sure the temperature of the coil and the terminals not to exceed the operating temperature range.
