B41799 Series 引线铝电解电容 :

TDK Corporation (TSE:6762) unveils B41799 series of ultra-compact aluminum electrolytic capacitors with axial-lead and soldering star designs, engineered to withstand operating temperatures of up to +140 °C. Tailored for demanding automotive applications, these components offer a high-capacitance and high-ripple current solution in a space-saving format. This enables designers to reduce the number of capacitors required in powertrain modules, such as electric power steering (EPS), fan control, and transmission systems. The new capacitors are available for rated voltages of 25 V and 35 V, with capacitance values ranging from 1800 µF to 13,000 µF. They offer ripple currents of up to 34.6 A (IAC,max) at 10 kHz and +125 °C case temperature, supported by low ESR, over 4000 h of useful life (at +125 °C, rated voltage, and rated ripple current), and vibration stability up to 60 g (optional). This robustness is particularly advantageous in xEV platforms operating within a 12-V board net, where thermal stress, mechanical vibration, and compact integration are critical design factors.
