Power Choke Coil (Automotive Grade)

*1: Measured at 100 kHz

*2: The proved current value for making the overall temperature rise of 40K, when mounted on a multi-layer board with

high-heat dissipation (heat dissipation constant 8.5 x 8.0 x 5.4 mm : approx. 27 K/W, 10.9 x 10.0 mm : approx. 23 K/W).

*3: The proved current value for making the overall temperature rise of 40K, when mounted on a 4-layer circuit board of

FR4 t=1.6 mm and DC current is applied.

*4: Saturation rated current : DC current which causes L(0) drop –30 %.

*5: Vibration resistance conditions : Amplitude: 5 mm or less, sweep speed: 1 oct / min, frequency 5-2000 Hz, 3 directions/2 hours each,

total 6 hours

*6: The solderability is guaranteed for 1 year only. The product out of expiration date shall not be used

．

◆ Within a suitable application, the part’s temperature depends on circuit design and certain heat dissipation conditions. This

should be double checked in a worst case operation mode. In normal case, the max.standard operating temperature of +150°C

should not be exceeded. Please contact for possible to use over 150

℃ condition. Temperature up to 180 ℃ may possibly be used.
