Axial-lead and soldering star capacitors
Compact
up to 150
°C
B41695, B41795
Applications
Compact design for automotive applications
Features
Up to 150
°C
operating temperature up to 55 V DC
Rated voltage up to 100 V upon request
High ripple current capability
High vibration resistance
Long useful life
Compact design
Optimized CV value
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.
