C1: Input capacitor Rated voltage : More than 50V Capacity : 33 to 220F, low impedance type Rated ripple current : More than 0.1Arms C2: Output capacitor Rated voltage : More than 25V Capacity : 100 to 470F, low impedance type ESR : Less than 0.39 Rated ripple current : More than 0.37Arms Evaluate it with the actual opportunity because it influences an output ripple voltage. C3: Noise reduction capacitor Rated voltage : More than 25V Capacity : 0.1 to 0.22F Film capacitor or ceramic capacitor The constant value should be evaluated in the product.
