Recommended the use of fast-acting type fuse 1.0A.
Rated voltage : More than 450V
Capacitance : 22碌F to 100碌F
Rated voltage : More than 25V
Capacitance : 100碌F to 1000碌F, low impedance type
ESR : Less than 0.18鈩?/div>
Rated ripple current : More than 0.62Arms
Evaluate it with the actual opportunity because it influences an output
ripple voltage.
Rated voltage : More than 450V
film capacitor, or Ceramics capacitor
Capacitance : 0.1 to 0.22碌F ;
Inductance : 1mH Rated Current : More than 0.41A
It is changed electrical characteristics by winding direction of Power Inductor
Resistance : 10鈩?to 22鈩?/div>
Power : More than 1/2W
Peak reverse voltage : More than 800V
Mean rectifying current : More than 1.0A
Peak forward surge current : More than 20A
This product can use even all the wave rectification.
If capacitance for input voltage smoothing is large, please use rectifier
diode that peak forward surge current is larger
Be sure to use it to protect this product from thunder surge and the static electricity.
