- Pin side is not shielded. It is recommended to set a pattern wider than the converter's bottom area right under the converter.
<Standard Usage>
VY-SL Series (5V, 9V, 12V, 15V)
VY-WL Series (±12V, ±15V)
- Recommended capacitor
C1=22µF -33µF (Electrolytic or multilayer ceramic capacitor)
C2=0.47-10µF (Electrolytic or multilayer ceramic capacitor)
Figure 3
- High frequency and low impedance capacitors are recommended.
- Recommended capacitor
C1=22µF -33µF (Electrolytic or multilayer ceramic capacitor)
C2, C3=0.47-10µF (Electrolytic or multilayer ceramic capacitor)
Figure 4
- Basically, external capacitors are not required, but noise can be lowered by reducing power line impedance and load line impedance.
- Noise can also be lowered by designing the pattern with short lead and not to make a loop.
