Hybrid Electrolytic Capacitors handle 30 g constant vibration.

Press Release Summary:



Packaged in V-chip, SMT case, HZC_V (125°C) and HZA_V (105°C) series are respectively rated 25–80 Vdc and 25–63 Vdc and, at max ratings, have 4,000 and 10,000 hr life rating. Both hybrid polymer-aluminum electrolytic capacitors feature ruggedized electrical and mechanical design and offer capacitance up to 330 µF and ripple current of 2 A RMS or greater. Support terminal, extended support base, and lead wire diameter lend to vibration resistance.



Original Press Release:



Hybrid Polymer-Aluminum Electrolytics Handle 30g with Very Low ESR, High Ripple Currents



New Bedford, MA – Cornell Dubilier Electronics, Inc. (CDE) has announced ruggedized versions of their SMT Hybrid Polymer-Aluminum Electrolytic Capacitors, now able to withstand continuous vibrations of up to 30g of stress. This rating has been accomplished through electrical and mechanical redesign. Hybrid polymer-aluminum electrolytic capacitors combine the very low ESR and high ripple currents of conductive aluminum polymer capacitors with the higher voltage and capacitance ratings of aluminum electrolytic technology.



Packaged in a compact V-chip, SMT case, the new capacitors are available in two series, the 125 °C HZC_V and the 105 °C HZA_V.  Both series have capacitance values up to 330 µF and ripple current values of 2 amps RMS or greater, in larger chip sizes. At maximum ratings, HZA_V capacitors have an exceedingly long life of 10,000 hours, with the HZC_V rated at 4,000 hours. The HZA _V is rated at 25 to 63 Vdc and 25 to 80 Vdc on the HZC_V.



CDE incorporated three important upgrades for vibration resistance.  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 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.



“The high vibration rating allows designers of ruggedized products to access the benefits of the hybrid polymer-aluminum electrolytic technology,” said Bill Haddad, Product Manager. “They are a particularly good fit where circuitry mounts to mechanical systems or for military transportation.” Other applications include industrial power conversion, lighting control and automotive applications.



Since its founding in 1909, Cornell Dubilier 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.



A global company, Cornell Dubilier has ISO-9001 certified manufacturing and distribution facilities in Liberty, SC; New Bedford, MA; Mexicali, Mexico; and Hong Kong.
