Cornell Dubilier Electronics, Inc. (CDE) has introduced a ruggedized SMT Aluminum Electrolytic Capacitor series, able to withstand continuous vibrations of up to 30g of stress. This durability makes the new AFK_V Series especially well-suited to military and transportation applications, as well as in robotics.
The AFK_V Series offers low impedance and up to 5,000 hours life @ 105 ºC, at rated voltage. Available capacitance values range from 10 μF to 6,800 μF, with voltage ratings of 6.3 Vdc to 100 Vdc.
Packaged in a metal V-chip, SMT case, the new capacitors use a combination of three mechanical enhancements that provide greater vibration resistance as compared with the standard SMT package. A support terminal was added to suppress vibration of the molded support base to the PCB, and therefore reduce contact stress. The support base was extended to create a high retention wall structure to better support the capacitor body. In an effort to reduce internal vibration of the capacitor winding, a larger diameter lead wire is used, which is very effective at eliminating internal lead breakage at critical stress points.
“By offering SMT aluminum electrolytics that are able to withstand high vibration, we give engineers a great solution to improve end-product durability,” said Bill Haddad, Product Manager. “Circuitry that is on-board rough terrain vehicles or in factory automation can reach high vibration levels.” Other applications include industrial power conversion, lighting control and automotive applications.
Since its founding in 1909, has been dedicated to advancing capacitor technology for new applications. The company combines innovative products with engineering expertise to provide reliable component solutions for inverters, wind and solar power, electric vehicles, power supplies, motor drives, HVAC, motors, welding, aerospace, telecom, medical equipment and UPS systems.
