EPCOS / TDK B41799 Aluminum Electrolytic Capacitors
EPCOS / TDK B41799 Aluminum Electrolytic Capacitors are ultra-compact aluminum electrolytic capacitors with soldering star designs, engineered to withstand operating temperatures of up to +140°C. These devices offer a high-capacitance and high-ripple current solution in a space-saving format, reducing the capacitors required in powertrain modules (EPS, fan control, and transmission systems). The B41799 aluminum electrolytic capacitors feature a capacitance range from 1800µF to 13000µF and a 25V to 35V voltage range with a useful life of 4000hrs at up to +120°C. These capacitors incorporate a SIKOREL-based construction that allows for a storage life of up to 15 years at +35°C and compliance with AEC-Q200 standards. The EPCOS / TDK B41799 Aluminum Electrolytic Capacitors are RoHS compliant and ideal for automotive electronics.
These capacitors can handle up to 34.6A (IAC, max) ripple current at 10kHz, low ESR, and include a useful life of 4000h at up to +125°C. The soldering star versions (B41799) provide flexible horizontal, vertical, or busbar mounting options.
