Working Principle

The M39003/01-7256/HSD capacitor is a surface mount device that uses the combined application of materials to produce a reliable electrical connection. The capacitor consists of two metal plates that are separated by a dielectric material. When a voltage is applied to the plates, it creates an electric field that stores energy within the capacitor. This energy is measured and stored in the form of electrical charge.

The dielectric material used in the M39003/01-7256/HSD capacitor is a tantalum oxide based ceramic. This material is capable of storing more electrical energy than other materials, and has a low leakage current. This results in a higher capacitance and higher temperature stability compared to aluminum or ceramic capacitors. The improved thermal stability also makes the device more reliable in different environments, and extends the life of the capacitor.

The HSS system ensures excellent protection against moisture and other contaminants, as well as improved electrical characteristics. The Sol-Gel coating increases the solderability and electrical performance of the device, making it even more reliable.
