Cornell Dubilier Type 101C: Low-ESR, Wide-Temperature Grade Aluminum Electrolytic Capacitor
The Cornell Dubilier Type 101C is a wide-temperature, low-voltage aluminum electrolytic capacitor designed for high-ripple current military and industrial applications. It offers full performance down to -40 C and solid performance to -55 C, making it ideal for demanding environments. Its exceptionally low ESR also makes it an excellent choice for power-supply output capacitor applications. The Type 101C features Thermal-Pak extended cathode construction, ensuring efficient heat flow from the capacitor element to the can in all mounting orientations.
