Axial-lead and soldering star capacitors
Up to 150
°C
B41693, B41793
Applications
Excellent reliable design for automotive applications
Features
High operating temperature capability up to 150
°C
Rated voltage up to 75 V DC
Low ESR
High reliability
Outstanding parametric stability
High ripple current capability
High vibration resistance
Long useful life
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
