Arrow's RF & Power business introduces expanded line of MLS flatpack aluminum electrolytic capacitors

May 13, 2014

Arrow Electronics, Inc. announced the availability and full design support capabilities for the expanded line of MLS flatpack aluminum electrolytic capacitors from Cornell Dubilier.

The new additions to the MLS Series includes a high-vibration package (HVMLS) and a high-reliability burn-in option (HRMLS). The new devices are ideally suited for military and commercial flight-based power systems that require high-energy density, rugged capacitors for bulk storage. Prior to these new Cornell Dubilier devices, relatively expensive wet tantalum capacitors were the only type suited for these environments.

The MLS family of capacitors are 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, easily cooled, and easily ganged for compact, high bulk storage. The 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 (g-force) vibration. The HRMLS version is burned-in up to 48 hours at rated voltage and 85°C, the established military standard for excellent reliability.

According to Cornell Dubilier, key features of the new devices include:

  • Near-hermetic welded seal
  • Stainless-steel case
  • 100 years expected operating life
  • Withstands more than 80,000 feet altitude
  • Type HV up to 50 g

The HVMLS and HRMLS versions may be ordered together by specifying type HVHRMLS to ensure extraordinary life and reliability in the most critical of applications.
