SMR Snap-In Aluminum Electrolytic Capacitors

Chemi-Con SMR Snap-In Aluminum Electrolytic Capacitors (AECs) feature a reduced size with cases ranging from 22mm x 25mm to 35mm x 50mm. These capacitors meet the demands of miniaturized power supplies with high ripple current capability. The series provides 2000 hours of endurance with full-rated ripple current applied at +85°C. These devices feature a voltage range of 400V_DC to 450V_DC and a capacitance range of 120µF to 1000µF. Ideal applications for Chemi-Con SMR Snap-In AECs include power supply input filters, bulk storage, and inverters.
