Tolerance of inductance : +40%/-20% for 1.3~6.8uH, 20% for 12~220uH. 2. Irated is the DC current which cause the inductance drop less than 25% of its nominal inductance without current and the surface temperature of the part increase less than 45oC. 3. Operating temperature : -20oC to 105oC (including self-temperature rise). DELTA ELECTRONICS, INC. (TAOYUAN PLANT CPBG) 252, SAN YING ROAD, KUEISAN INDUSTRIAL ZONE, TAOYUAN SHIEN, 333, TAIWAN, R.O.C.
