The gridded anode increases the surface area of the anode, which allows for more electrons to be drawn to the anode, resulting in an increase in capacitance. The tantalum sponge cathode also helps to increase the capacitance of the capacitor due to the increased dielectric properties of the material.

As mentioned above, the M39003/01-2985/TR is designed for use in high temperature environments. The capacitor is constructed with a housing made of aluminum, which is capable of withstanding temperatures up to 125°C. Additionally, the anode and dielectric material are hermetically sealed, making the capacitor resistant to humidity and other environmental factors.

In conclusion, the M39003/01-2985/TR is an excellent choice for a variety of applications due to its high capacitance ratings and outstanding stability. Its design allows it to operate in high temperature environments and provide reliable performance. Its gridded anode and tantalum sponge cathode give it additional capacitance, and its hermetically sealed design make it resistant to environmental factors. These characteristics make the M39003/01-2985/TR an ideal choice for a wide range of applications.
