Axial-lead and soldering star capacitors
Long useful life, compact
up to 140
°C
B41692, B41792
Applications
Compact design for automotive applications up to 140
°C
Features
Up to 150
°C
operating temperature at reduced voltage
applied
Long useful life, 2000 h at up to 140
°C
Very high ripple current capability
Compact design
High vibration resistance
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 with insulating sleeve
Negative pole connected to case
Terminals
Axial leads, welded to ensure perfect electrical contact
Also available with soldering stars
Taping and packing
Axial-lead capacitors will be delivered in pallet package.
Capacitors with d

30 mm are also available taped
on reel.
Soldering star capacitors are packed in cardboard.
