Be sure to use fuse for safety.
For actual usage, Please kindly evaluate and confirm our part mounted in your product, Especially, Please make sure to confirm the load current does not exceed Max. rated current by using the current probe. External components setting FUSE: fuse C1, C2: Input capacitor C3: Output capacitor Please make sure to use quick acting fuse (1A) above 450V, 22 to 100F Ripple current 0.7Arms above above 30V, 220 to 1000F, Low impedance ESR:0.18 Max. Ripple current 0.65Arms above Impedance of capacitor effects the output ripple voltage.

C4: For noise terminal voltage Above 600V, 0.1 to 0.22F reduction capacitor Film capacitor or Ceramic capacitor Reduce the noise terminal voltage. The constant value should be evaluated in the product. L1: Power inductor Inductance:1.0mH, Rating current: above 0.74A Choose components that do not easily get magnetically saturated in high temperature. Recommended part : C13-FR 1.0mH (MITSUMI) Above 1000V, current: above 1.0A Fast recovery diode Please note that both the switching and efficiency characteristics of the module are affected by this diode. Recommended products: UF4007 (VISHAY) Use a rectifying diode with the peak reverse voltage of 1kV or higher, the average rectification current of 1A or larger and the peak surge current of 20A or larger. When using an input capacitor of a large capacity, choose a component that endures the inrush current on power-up. This product is compatible with full-wave rectification.
D1: Flywheel diode
D2: Rectifier diode
R1: For noise terminal voltage 10 to 22, 1W Reduce the noise terminal voltage. reduction capacitor The constant value should be evaluated in the product. ZNR: Varistor Varistor must be used. It protects this part from lightning surge and static electricity.
