Sturdy and durable SMT aluminum electrolytic capacitor series, can withstand continuous vibration up to 30g stress. This durability makes the new AFK_V series particularly suitable for defense and transportation applications as well as robotics.
The AFK_V series offers low impedance and a long life of 5,000 hours at 105C at rated voltage. Available capacitance values range from 10μF to 6,800μF, with a rated voltage of 6.3VDC to 100VDC.
Compared with the standard SMT package, the new capacitor is packaged in a metal V-chip SMT case, which combines three mechanical enhancements to provide greater vibration resistance. A support terminal was added to suppress the vibration of the molded support base to the PCB, thereby reducing contact stress. The support base is expanded to form a high-retaining wall structure to better support the capacitor body. The company said that in order to reduce the internal vibration of the capacitor windings, a larger diameter lead was used, which was very effective in eliminating internal lead breaks at critical stress points.
"By providing SMT aluminum electrolysis that can withstand high vibrations, we provide engineers with an excellent solution to improve the durability of the final product," said Bill Haddad, product manager. "Electric circuits on rough vehicles or in factory automation can reach very high levels of vibration."
Other applications include industrial power conversion, lighting control and automotive applications.
The company also announced a ruggedized version of its SMT hybrid polymer aluminum electrolytic cell, which now also can withstand continuous vibrations up to 30g. This rating has been completed through electrical and mechanical redesign. Hybrid polymer aluminum electrolytic capacitors combine the extremely low ESR and high ripple current of conductive aluminum polymer capacitors with the higher rated voltage and capacitance of aluminum electrolytic technology.
