Cornell Dubilier MLP/MLS Aluminum Electrolytic Capacitors

Cornell Dubilier MLP Aluminum Electrolytic Capacitor's high-energy storage and box-shape make it perfect for voltage holdup or filtering in military SEM-E modules, telecom circuit packs and computer cards. Cornell Dubilier MLP Aluminum Electrolytic Capacitors deliver up to 20 joules of energy storage in a 1/2" height with 50 year's life at +45ºC. Cornell Dubilier MLS Aluminum Electrolytic Capacitors extend the super performance of the MLP from a maximum operating temperature of 85ºC to 125ºC. The MLS incorporates a rugged, stainless steel case which assures flatness to beyond 125ºC. Cornell Dubilier MLS Aluminum Electrolytic Capacitors are perfect for high-reliability military systems and applications operating above 85ºC.

Cornell Dubilier SLP / SLPX Type Snap-In Capacitors

The Cornell Dubilier SLP / SLPX Type High Voltage Snap-In Capacitors have a smaller case size with higher capacitance and a voltage range from 10Vdc to 450Vdc. The ripple current and long life are 3000h at their rated voltages (SLP @ 105ºC, SLPX @ 85ºC), making the SLP / SLPX the best value package snap-in series. The smallest case size for either series is 22x25mm and the largest being 35x50mm. The Cornell Dubilier SLP / SLPX Type High Voltage Snap-In Capacitors are ideal as a drop-in replacement for next-generation switching power supplies, inverters, and DC filtering.

Cornell Dubilier Life and Temperature Calculators
Screw Terminal Applet

Cornell Dubilier's Screw Terminal applet can automatically page through CDE's catalog ratings and fill in the rated capacitance, full-can capacitance and typical ESR after you've entered the capacitor type, case size and rated voltage. It even gives you the option to fill in your capacitor's ESR values at your operating temperature and ripple frequencies if you have your own data.

Impedance Modeling Applet

CDE offers Spice models of many wet aluminum electrolytic capacitors. Cornell Dubilier has an online impedance modeling applet that allows the user to select any standard catalog part number among 16 types. The capacitance, ESR, and impedance are then graphed versus frequency at several temperatures. A Spice simulation program listing is available and this model is readily cut and pasted into a Spice simulator.

Snap-In Applet

There's even more design power for you, a companion for Cornell Dubilier's powerful computer-grade life and temperature calculator except now for snap-ins! It precisely calculates how long CDE's various types of snap-in capacitors will last in your application and at what operating temperature.

Plug-In Applet

For the ultimate robust package in medium-size aluminum electrolytic capacitors, check out CDE's plug-in ratings. The plug-in applet covers types 4CMC, 400C, 420C, 450C, and 401C. These capacitors have new, aggressive ratings that offer longer life, higher ripple, and more capacitance than small screw-terminal capacitors, and competitive performance and price (not to mention better mechanical integrity) compared to 40, 45, and 50 mm diameter snap-in's.
