High frequency transformer is a kind of electronic transformer which work frequency exceed 10 kHz, it widely used in switch power supply, inverter power supply, power meters, Telecom, inverter welding machine and photovoltaic, etc.
High frequency transformer as the most important parts in switch power supply, there are so many topological structure, such as full/half Bridge structure.
Sitong Electronic not only could manufacture forward half/full bridge transformer, also have other circuit transformers, such as flyback transformer, converter transformer, inverter transformer, push-pull transformer, LLC transformer, etc.
Advantage:
1.Our materials resource from the suppliers in our UL lists (UL E364966). They have passed RoHS or UL certificates. It is available for your pointed supplier. If there are any changes about the materials or suppliers, we will inform in advance.
2.Sitong Electronic has passed ISO9001:2015, our procedures according to the ISO requirements strictly. Our SOP is same as the customer’s requirements, and the batch goods is same as the delivered samples.
3.The goods will be inspected 2 times before delivery to ensure the best quality: All the products will through testing before varnish, and will be 100% tested before package. Twice testing including: turns, inductance, Hi-pot, leakage inductance, DCR, visual inspection, etc.
