Cornell Dubilier Electronics, Inc. Announces Higher Voltage Values for its MLSH Slimpack Series of Hermetically Sealed Aluminum Electrolytic Capacitors

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.

New Yorker Electronics Introduces Cornell Dubilier’s Newest Line of MLS/MLP Flatpack Aluminum Electrolytic Capacitors

New Yorker Electronics has introduced Cornell Dubilier’s newest line of MLS/MLP Flatpack aluminum electrolytic capacitors into its vast product catalog. This expanded line includes a high vibration package, type HVMLS and a high reliability burn-in option, type HRMLS. Applications are mainly for military and commercial flight based power systems that require high energy density, high reliability, rugged capacitors for bulk storage, where relatively expensive wet tantalum capacitors had previously been the only type suited for these environments. The MLP is the square-peg component that fits the square-holes in electronic assemblies. The MLP delivers up to 20 joules of energy storage in a 1/2” height with 50 year’s life at +45 ºC. They can readily be heatsinked to it to double the ripple-current capability. The MLP’s high-energy storage and box-shape make it ideal for voltage holdup or filtering in military SEM-E modules, telecom circuit packs and computer cards. The MLS family of capacitors are packaged in flat, stainless steel cans, one-half inch in height with a near hermetic, precision welded construction and tested up to 80,000 feet. Their flat form factor allows them to be fit into tight spots, easily cooled, and easily ganged for compact, high bulk storage. The high vibration HVMLS version is further enhanced with ruggedized internal terminations and compressed can edges that keep the internal winding secure when tested up to 50g's of vibration. The high reliability version, type HRMLS, are burned-in at rated voltage and 85°C, which is long recognized as the established military standard to achieve excellent reliability. Both ruggedized and high reliability options may be ordered together by specifying type HVHRMLS to ensure extraordinary life and reliability in the most critical of applications. The near-hermetic welded seal assures long life: a 50-year life with the MLP and a 100-year life with the MLS. Other features include: MLS - Stainless-steel case: MLS – regular, HVMLS - High Vibration, HRMLS - High Reliability, HVHRMLS - High Vibration /High Reliability and Rated to 125oC. MLP - Aluminum case: Rated to 85oC. Vibration testing: MLS - up to 10 g’s and HVMLS - up to 50 g’s. Both the MLP and MLS Flatpacks are currently in stock at New Yorker Electronics and ready for shipment by visiting the Web site or calling 800-536-1887.
