Type MLSH 125 °C Hermetic Slimpack, Aluminum Electrolytic Capacitor

The world’s only hermetically sealed aluminum electrolytic capacitor with

glass-to-metal seal, type MLSH has extraordinary long life and rugged

construction for the most demanding power electronics applications.

Type MLSH has superior capacitance retention compared to axial wet

tantalum capacitors at -55 °C. Packaged in a robust stainless steel case

capable of withstanding 80g’s, it replaces 3 or more axial wet tantalum

capacitors in parallel. Unlike wet tantalums that require voltage derating

at temperatures above 85 °C, type MLSH capacitors are rated for full

operating voltage at 125 °C and tested to 5000 hrs at rated voltage and

temperature.

Highlights
