Axial-lead and soldering star capacitors B41692, B41792

Long useful life, compact  up to 140 °C

Applications

Compact design for automotive applications up to 150 °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 × l ≤ 16 × 30 mm are also available taped
on reel.
Soldering star capacitors are packed in cardboard.
