Copper conducts electricity and heat very well.
Taking advantage of these characteristics, copper is used for components of various home electric appliances.
Pipes/heat exchanger, fan transistor & MOS array, etc.
Coils (deflection yoke), printed circuit board, power supply IC, etc.
Compact switching power supply IC, motor driver IC, hall IC, etc.
Output transistor, power rectifier diode, and LED
Printed circuit board, surface mount/low consumption current/low output voltage regulator IC, etc.
Printed circuit board, copper wires, hall IC, and secondary rectifier SBD
Surface mount/low consumption current/low output voltage regulator IC, battery reverse connection preventing SBD, etc.
Printed circuit board and battery reverse connection preventing diode
