Aluminum Electrolytic Capacitors are compact and snap into place.

Press Release Summary:



Snap-in capacitors are manufactured with can-wall groove that supports top, which is added after insertion of capacitor element. Because cans are nearly full, units are more compact than previous models. Type 380LQ is rated for
-40 to 85°C operation; Type 381LQ is rated for -40 to 105°C operation; and Type 380LQ has a voltage range from 160 to 450 Vdc in capacitance values from 82 to 3900 hF.




Original Press Release:


New Snap-in Aluminum Electrolytic Capacitors are 25% Smaller


Responding to the continuing pressure to make power supplies, motor drives, UPS systems and electronics in general smaller Cornel Dubilier announced immediate availability of two new snap-in aluminum electrolytic capacitor types.

Type 380LQ is rated for -40 to 85 °C operation and is on average 27% smaller and more than 10 mm shorter than similar capacitors such as the firm's Type 380L. The other type, 38ILQ is rated for -40 to 105 °C operation and is on average 23 % smaller and more than 5 mm shorter that similar, 105 °C rated capacitors such as the firm's Type 381L. Both types range up to 50% smaller volume and up to 30mm shorter cans than comparable types.

Type 380LQ has a voltage range from 160 to 450 Vdc and in capacitance values from 82 to 3900 hF. Case sizes range from 22 mm diameter by 25 mm height to 35 by 50 mm. The rated life test is 2000 hours at 85 °C with full load and conducted per EIA Interim Standard 749. This test procedure requires mounting the capacitors sideways and is more severe than typical industry tests in which the capacitors sit on an oven shelf. The 380LQ is priced in OEM quantities from 99 ¢ to $4.65 according to capacitance and voltage.

Type 381LQ has a voltage range from 160 to 450 Vdc and in capacitance values from 100 to 3300 pF. Case sizes range from 22 mm diameter by 25 mm height to 35 by 50 mm. The rated life test is 8000 hours at 85 °C with full load and also conducted per EIA Interim Standard 749. The 380LQ is priced in OEM quantities from 93 ¢ to $5.11 according to capacitance and voltage.

The reduction in case size has been made possible by changing manufacturing to install the can-wall groove that supports the top after insertion of the capacitor element. This allows the capacitor element diameter to be large, and the cans are more nearly full. Since the capacitor elements are actually the same as before, these new capacitor types deliver substantially the same performance. This enables designers to downsize equipment and retain the original performance. Full specifications are at www.cornell-dubilier.com.
