Application Guide

• 450V: 220V–240V AC input SMPS bulk filter (rectified ~310V DC, 450V gives ~30% headroom)
• 400V: 110V AC input or PFC-regulated 220V circuits
• All share Ø25mm + 10mm footprint → drop-in by hole pattern
• Verify height: 30mm vs 40mm body before ordering

Cross-reference / Compatible Series

Nichicon GU / GG mini • Rubycon USG compact • EPCOS B43501 • Chemi-Con KMR • CDE 380LQ • Jianghai CD29H

Replacement Notes

• 400V and 450V are not interchangeable – select by circuit rail voltage
• Upgrading 85°C → 105°C is safe (longer life, lower ESR)
• Never install polarized capacitor in signal coupling or AC path
• Reverse polarity = vent rupture

Condition

100% brand new, dry-stored, no bulge, no leak, leads straight. RoHS-compliant series available on request.
