Cornell Dubilier Electronics announces it has expanded its line of MLS Flatpack aluminum electrolytic capacitors to include 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 expensively wet tantalum capacitors had previously been the only type suited for these environments.

The MLS family of capacitors is packaged in flat, stainless steel cans, one-half inch in height with a near-hermetic precision welded construction, tested up to 80,000 feet. Their flat form-factor allows them to be fit into tight spots and easily cooled and 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 50 g of vibration.

The high-reliability version, type HRMLS are burned-in up to 48 hours at rated voltage and 85°C, 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.
