ALC40 Datasheet, PDF (1/6 Pages) Kemet Corporation – IEC 60384-4 Long Life Grade 40/105/56

ALC40 Series 105°C
• Compact Size
• Long life, 9000 hours at 105 °C (Ur, Ir applied)
• High ripple current
• Excellent surge voltage capability
• Optimized designs available on request
application
Basic design
Suited for high reliability and long life
applications such as frequency converters,
UPS systems and switch mode power
supplies, but the extended temperature
range allows increased ripple currents at
lower temperatures.
The ALC40 series of snap-in capacitors
feature the same high ripple currents and
long life characteristics as the ALC10 series
but can operate at higher temperatures.
