Axial-lead and soldering star capacitors
Compact
up to 140
°C
B41692, B41792
Applications
Automotive electronics
Features
Long useful life, 2000 h at up to 140
°C
High ripple current capability
Compact design
High vibration stability
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.
RoHS-compatible
Construction
Charge/discharge-proof, polar
Aluminum case with insulating sleeve
Negative pole connected to case
Terminals
Axial leads, welded to ensure perfect electrical contact
Soldering star for upright mounting on PCB available
Alternative axial-lead design with double-sided plates for
horizontal mounting available upon request
Taping and packing
Axial-lead capacitors will be delivered in pallet package
Capacitors with d
