EE5 type SMD transformer is the power transformer whose working frequency exceeds the medium frequency (10 kHz). It is mainly used as isolation transformer in switching power supply, inverter and solar system. According to the working frequency, it can be divided into several grades: 10khz-50khz, 50khz-100khz, 100kHz ~ 500kHz, 500kHz ~ 1MHz, 10MHz or above.
The characteristics:
(1) Current distribution
A typical isolated transformer has a number of parallel windings. Each secondary winding is coupled to the corresponding primary winding. Therefore, the ampere-turns generated by the secondary winding current are equal to the corresponding primary winding (ignoring the excitation current). This characteristic is useful for parallel rectifier circuits particularly. Winding current distribution is equality; it needn’t resistance or other components in parallel rectifier circuit.
(2) High current density
10 kHz -1 MHz transformers have excellent characteristics on temperature rise. Because of this, it can achieve high current density in very small packages.
(3) Efficiency
By adjusting the leakage inductance so that it can have a very fast switching time, very low cross loss, it can achieve very high efficiency. The transmission loss between the secondary side winding and the primary side winding is very small.
(4) High power density
Because of the small size of the circuit transformer element, it has excellent temperature dissipation characteristics, so it can be closely packaged with the related semiconductor devices and inductors to achieve high power density. It has a current density of up to 30A/ module.
(5) Material with RoHS or Reach Certificate
The whole electronic transformer is made up of quality assurance material suppliers, you could point suppliers also.
(6) Save the cost of components connected to it
Because of small leakage inductance and low switching loss, the stress applied to the components connected will be reduced. Therefore, the components could be lower cost and lower power quota which connected to our PCB transformer.
