Type MLSH 125 °C Hermetic Slimpack Ultra Long Life, Aluminum Electrolytic Why Use Type MLSH ? Advantages Over Wet Tantalum The world’s only hermetic aluminum electrolytic capacitor with glass-to-metal seal. Type MLSH has extraordinary long life and rugged construction for the most demanding power electronics applications. Aluminum electroytics have much higher capacitance retention at low temperature. See figures 1 through 3 below. Highlights Figure 1 Hermetic Aluminum Electrolytic Capacitance @ -55°C MLSH222M040JK0C (2200µF, 40Vdc) 2000 Capacitance (µF) 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. • Superior capacitance retention at -55 ºC compared with 3 or more wet tantalum capacitors in parallel • Considerably lower cost • Lighter than equivalent bank of wet tantalums • Aluminum electrolytics do not contain conflict materials • Not subject to shortages and market price fluctuations 1500 1000 500 0 10 1000 10000 Figure 2 Wet Tanatalum Capacitance @ -55°C 4 X (1000µF, 60Vdc*) D-Size Wet Tantalum Caps in Parallel * Derated to 40 Vdc for -55°C to 125°C Operating Temp Range 4000 3500 3000 2500 2000 1500 1000 500 0 10 100 1000 10000 Frequency (Hz) Figure 3 For information and samples, please contact: Capacitance Ratios @ -55°C 1 MLSH Versus 4 D-Case Wet Tantalum Caps in Parallel 2.50 Capacitance Ratios Mario DiPietro Flatpack Product Manager [email protected] 864-843-2277 ext. 2395 100 Frequency (Hz) Capacitance (µF) • Hermetically sealed aluminum electrolytic (no dry-out) • 100% tested per MIL-STD-883, Method 1014.2 • High capacitance retention at low tempera- ture • 80 G Vibration • 125 °C maximum operating temperature (no derating required) • Lighter than equivalent wet tantalum • 1.5 V reverse voltage • DC life test to 5000 hrs 2.00 1.50 1.00 0.50 CDE ENERGIZING IDEAS CORNELL DUBILIER 0.00 10 100 1000 10000 Frequency (Hz) Note: The different frequency vs. temperature responses of these two dielectric systems gives rise to a capacitance ratio that varies not only with temperautre, but also with frequency.
