Frequently Asked Questions
Q: What are the dimensions of these 400V 390uF electrolytic capacitors?
A: Each NioCen 400V 390uF aluminum electrolytic capacitor measures 35mm × 35mm, making it a compact yet high-capacity component suitable for most standard PCB layouts and enclosures.
Q: Are these capacitors compatible with through-hole PCB designs?
A: Yes. These capacitors feature a through-hole (radial lead / hard feet) package type, which means they are designed to be inserted through drilled holes on a PCB and soldered on the reverse side — ideal for both DIY projects and professional repair work.
Q: What types of circuits are these 400V 390uF capacitors best suited for?
A: These are general-purpose aluminum electrolytic capacitors well-suited for high-voltage filtering and energy storage in applications such as AC-DC power supplies, inverters, variable frequency drives, motor control circuits, and audio amplifier power stages.
Q: What is the difference between the 2-pack and 10-pack options?
A: Both packs contain the same NioCen 400V 390uF capacitors. The 2-pack is great for single repairs or small projects, while the 10-pack offers better value per unit and is ideal for workshops, bulk repairs, or stocking your electronics parts inventory.
