Typical Time To Trip At 25℃
TR 60V 72V PPTC In A Small Transformer Application Plan
1. Transformer
The main function of the transformer: Voltage conversion; impedance
transformation; isolation; stable voltage, etc. Commonly used in a
variety of power among a small charge circuitry. The main failure
mode short circuit, open circuit.
2. The new generation transformer characteristics?
A. In order to reduce costs, power margin designing smaller, fast
heating.
B. The application of copper is small and can only work properly,
easily large currents blown.
C. The limit on the cost reduction in the strength of enamelled
only meet the specified application, easy to crack, high
temperature aging, internal short circuit.
D. Limiting costs resulting core loss, high fever situation.
