Type 381LL/383LL, 105 °C Long Life, Snap-In Aluminum
8,000 Hour Snap-in
Type 381LL snap-ins are designed and tested to meet the high
ripple current demands of inverter DC link applications where
long-life of the capacitor bank is essential to system reliability.
The 381LL series uses the most advanced electrolyte system
that delivers reliable performance and stability of parameters
over the life of the capacitor.
