ET, UU type series
The characteristics and scope of application:High-current, low temperature rise and excellent anti-EMI performance.
Widely used in Useful in switches power supply and other electrical equipments curbing “pollution” to the grid and electromagnetic interference from the grid to the equipment.
TEST EQUIPMENT AND CONDITIONS
Inductance is measured with HP-4284A LCR meter or equivalent.
S.R.F. measured with 4991A Impedance analyzer orequivalent.
Maximum allowable DC current is that which causes a 10% inductance reduction ofthe initial value, or
coil temperature to rise by 40℃,whicheveris smaller. (Reference ambient temperature 20℃)
Operatingtemperature : -40℃~+125℃ (Including self-heating).
FEATURES
Magnetic-resin shielded construction reducesbuzz noise to ultra-low levels
Metallization on ferrite core results inexcellent shock resistance and damage-free durability
Closed magnetic circuit design reduces leakageflux and Electro Magnetic Interference (EMI)
30% higher current rating than conventional Inductors of equal size
Takes up less PCB real estate and save morepower
