Large-size capacitors
Automotive
up to 140
°C
B41605
Long-life grade capacitors
Applications
High-reliability equipment in automotive power electronics,
e.g. integrated starter alternator
Applications with highest ripple current load at high
frequencies
Features
High reliability and long useful life, up to 2000 h at 140
°C
Very high ripple current capability optimized for high
frequencies
Compact design
Vibration resistance up to 40
g
Shelf life up to 15 years at storage temperatures up to 40
°C.
To ensure solderability, the capacitors should be built into the
application within one year of delivery. After a total of two
years' storage, the operating voltage must be applied for one
hour to ensure the specified leakage current.
Construction
Charge/discharge-proof, polar
Aluminum case, fully insulated
Up to 40
g
vibration stability version with wired terminals and
corrugation
Snap-in solder version with pins to hold component in place
on PC-board
Minus pole not insulated from case
Overload protection (safety vent)
Without insulation sleeve upon request
Terminals
Standard vibration version with wired terminals,
weldable and solderable
Snap-in with 3 terminals, protection against polarity reversal
Up to 40
g
vibration stability version with wired terminals,
weldable and solderable
