Hermetically Sealed Aluminum Electrolytic Capacitor Line Expands to Higher Voltages The world’s only hermetic aluminum electrolytic capacitor line with a glass-to-metal seal, now available up to 250 Vdc.

Hermetically Sealed Aluminum Electrolytic Capacitor

Cornell Dubilier Electronics, Inc. (CDE) has announced significantly higher voltage values for its MLSH Slimpack series of hermetically sealed aluminum electrolytic capacitors. These unique components feature a true glass-to-metal seal that prevents dry-out of the capacitor electrolyte. As a result, they provide extraordinarily long life (5,000 hours) to more than meet the most demanding applications for military and aerospace. With the line expansion just announced, they are now available in nine values, from 120 µF to 3,200 µF, with ratings up to 250 Vdc.

The hermetic Slimpack is an offshoot of the well-established non-hermetic Flatpack series. The new MLSH Slimpack can be used as a replacement for parallel and series banks of wet tantalum capacitors for both new and existing designs. This change is especially beneficial where bulk storage is paramount. MLSH Slimpack devices measure 1.0” x 1.5” x 0.5”, weigh less and have more capacitance than a parallel bank of three or more wet tantalum capacitors. High rated capacitance is maintained at temperatures as low as -55 °C, a key requirement for power supplies used in military and aerospace applications. Top-end temperature rating is 125 °C.

All devices in the MLSH Slimpack series feature rugged stainless steel cases with a vibration rating of 80g. In most applications, there are significant cost and space savings vs. a comparably rated bank of wet tantalum capacitors. The new high-voltage MLSH Slimpacks eliminate the need for series banking.

Since its founding in 1909, CDE 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.
CDE’s hermetic MLSH Slimpack aluminum electrolytic capacitors are available from Digi-Key, Mouser and TTI.
