RLA Snap-In Aluminum Electrolytic Capacitors Chemi-Con RLA Snap-In Aluminum Electrolytic Capacitors (AECs) offer a high-rated ripple current capability for applications such as inverter controls. The series is rated at 3000h life with the full-rated ripple current applied at 85℃. The RLA series RMS ripple current capability is 20% more than snap-in capacitors in the same case size. Chemi-Con RLA Snap-IN AECs have a 30mm to 35mm diameter and a 35mm to 55mm length.
