Performance
|
HF-transformer conform to IEC/EN61558-2-17 for SMPS
|
|
|
HF-transformer, HF-inverter, ferrite trasnformer, SMPS transformer
|
|
Application
|
Suitable as HF-transformer for power integrations (TOPSWITCH,TINYSWITCH), Advanced Techology and ST(VIPer). This size can also be built as a choke.
|
|
Voltages
|
according to customer specification, more than one input and output voltages are possible
|
|
Frequency
|
20 kHz up to 300 kHz, special types up to 500 kHz
|
|
Core material
|
N87 or PL7 for high power, with other materials it’s less power
|
|
Temperature class
|
F (155°C) if varnished and B(130°C) if potted
|
|
Temperature
|
Ambient 40°C, higher ambient temperatures decrease the power
|
|
Protective class
|
Fire class UL94V0, IP00 conform to DIN 40 050
|
|
Winding
|
with lacquered copper wire, HF litz, foil or triple insulated Furukawa wire, interlaced constrcution for best magnetic coupling
|
|
Construction
|
varnished under vacuum (open version) with class H varnish or potted under vacuum in a housing
|
|
Terminals
|
Print, SMD version or free wires
|
|
Safety
|
Margins to redeem air- and creepage distances. A screening is possible, but the secondary power will decrease.
