description

performance

switched mode power supply transformer according to

 

IEC EN61558-2-17 for SMPS, HF-transformer, ferrite transformer

application

for Power Integrations (TOPSWITCH, TINYSWITCH) Advanced Techology and ST(VIPer).

 

types can also be constructed as an HF choke.

voltages

to customer demand, also more input and output voltages are possible

frequency

20 kHz to 300 kHz, extra types to 500 kHz

core material

N87 oder PL7 for high power, with other material less power

insulation class

F (155°C) for lacquered and B(130°C) for potted components 

temperature

ambient 40°C, higher temperatures

 

decrease the secondary power

protective class

fire class UL94V0, IP00 according to DIN 40 050

winding

with lacquered copper wire, HF-litz wire, foil or triple insulated Furukawa wire, interlaced construction for best magnetic coupling

construction

vacuum varnished (open types) with class H impregnation varnish or vacuum potted in a case

terminals

Print, SMD or with free wires construction

safety

margins for air- and creepage-distance

 

screening possible, secondary power will decrease
