MLP/MLS Flatpacks Go Military Top of Page

Planar Array Caps

The MLP in aluminum and MLS in stainless are now available as DSCC military types.

Flatpack aluminum electrolytic capacitors provide high-density storage in power hold-up applications for DSCC and other long lifetime, RoHS-exempt applications. Housed in compact packages with a half-inch profile and lengths from 1.5 inches to 3.0 inches, these flatpacks offer significantly higher power-density than screw-terminal packages. They can be heat-sinked to double their rated ripple capacity and both package options offer capacitance values up to 47,000 μF. The aluminum-housed MLP operates up to 85°C with rated voltages up to 450 Vdc. The stainless steel-case housed MLS operates to 125°C with rated voltages up to 250Vdc.

Snap-In Aluminium Electrolytic Capacitors - 3000 Hour Life and Superior Performance Top of Page

Snap in Capacitors

Providing power electronics design engineers with capacitors that combine proven high ripple current performance and economical pricing, Cornell Dubilier recently introduced two new snap-in aluminum electrolytic capacitor series with extended voltage rating up to 450Vdc. Designated the Type SLP (105°C) and SLPX (85°C) series, the capacitors are targeted for next generation switching power supplies, DC filtering circuits in inverters and motor drive applications.

Both the Type SLP and Type SLPX capacitors are available in diameters from 22 to 35 mm and lengths from 25 to 50 mm, with 10 mm spacing snap-in leads. Standard capacitance values for the Type SLP Series range from 47 to 56,000 μF, tolerance ±20%, with voltages from 10 to 4 50 Vdc. Standard capacitance values for the Type SLPX Series range from 68 to 82,000 μF, tolerance ±20%, with voltages from 10 to 450 Vdc. Special ratings are also available.
