SRW Series
(General Transformers, Barrierless Transformer®)
GENERAL TRANSFORMERS, BARRIERLESS TRANSFORMER®
The SRW series transformer for switching power supplies utilizes
ferrite materials, which makes it possible to achieve an incredibly
high efficiency in the required frequency range.
FEATURES
• By using high efficiency ferrite cores suitable for power conversion
with very low power loss and large magnetic flux density it is
possible to design transformers that is quite compact in size and
high efficiency.
• A wide variety of shapes and sizes from low output to high
output power, gives great flexibility of design switching power
supply.
• Bobbins and other components are also available which are
capable for a variety of safety regulations such as UL, CSA and
VDE.
APPLICATIONS
Transformers and Inductors for switching power supplies used for
TVs, CRT Monitors, VCRs, DVDs, printers, air conditioners, AC
adaptors, etc.
PRECAUTIONARY ITEMS REGARDING THE PRODUCT
• The maximum output power is a guideline for Flyback converter
topology operating at 50kHz. There may be differences depending
upon the circuit topologies.
• Special ferrite materials produced for power transformers with
large magnetic flux density are used in the ferrite core, so that
temperature rise of transformer is within 45°C in standard design
condition.
• Transformer temperature may rise even during normal operation, it
is advisable that you provide a sufficient mounting distance from
parts such as electrolytic capacitors, which do not withstand heat
well.
• A beat sound noise may be generated even under normal
operation (no harmful effect on usage).
• Please consult with us concerning usage outside of ratings.
• The products has not acquired approval for safety regulations,
however, it has been constructed with materials and structures
that meet with all types of safety regulations. Please consult with
us about individual categories concerning the acquisition of
safety regulations.
• Please make inquiries before use regarding industrial properties
outside the ownership of our company regarding the contents
stated here.
• When designing transformers, please feel free to contact with us
concerning designs for ferrite materials and standard bobbins,
which are not listed.
• All specifications are subject to change without notice.
