Cornell Dubilier Electronics, Inc. (CDE) has introduced the latest in its series of Flatpack ruggedized flat aluminum electrolytic capacitor, the MLSG. This series targets compact power supply applications in military and aerospace, as well as other critical systems. Design enhancements and a new electrolyte push the MLSG to nearly double the operating life of its predecessor, at no added cost.
The world’s only hermetic aluminum electrolytic capacitor line with a glass-to-metal seal,
now available up to 250 Vdc.
Cornell Dubilier Electronics, Inc. (CDE) introduces the world’s only hermetic aluminum electrolytic capacitor with a glass-to-metal seal. With no dry-out mechanism and high capacitance retention at low temperatures, this technology is poised to replace banks of costly wet tantalum capacitors.
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.
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.
Covering 21 of our most popular series of aluminum electrolytic capacitors — including FlatPack, Screw Terminal, Snap-In and Plug-In types — our Aluminum Electrolytic Impedance Modeler / SPICE Model Generator will create interactive plots of capacitance, ESR and impedance versus frequency and temperature. It will also generate a Pure SPICE netlist that can be pasted into your circuit modeling software. Click here to go to the calculator page.
CDE Power Conversion Type PC Series capacitors deliver a full 60,000 hour life at rated voltage, at a hot-spot temperature (area reaching the highest temperature) of 85°C. Type PC capacitors are wound using a high crystalline metallized polypropylene (HCPP) film, which possesses an extremely low dissipation factor. Click here to read technical paper
Based on your specified operating conditions of voltage, ripple current, heatsink characteristics, airflow and ambient temperature, this model calculates the internal hotspot temperature and expected lifetime, reliability and failure rate.

While steady-state analysis of aluminum electrolytic capacitors is straightforward, predicting transient electrical and thermal response is much more involved. In this presentation the modeling of transient electrical, thermal and lifetime behavior of aluminum electrolytic capacitors is discussed, focusing on large (> 0.1 liter) DC link capacitors.
