The main reasons for extrusion scratches. Extruded profiles may be scratched in many operations, but they are mainly related to molds, equipment and human operation. First of all, during the long-term use and maintenance of the mold, certain knife marks and scratches will inevitably occur on the surface of the mold.
Capacitance, or capacitance rating, is the amount of energy that can be stored in the capacitor. The higher the capacitance rating, the more energy that can be stored. Generally speaking, you should always replace like-for-like when it comes to capacitors – meaning if your capacitor has a capacitance rating of 10μF, you should …
A supercapacitor differs from other types of capacitors due to its large surface area and thin dielectric layer between the electrodes. As a result, their capacitances are much higher than those of regular capacitors [3]. Supercapacitors have a much higher energy storage capacity when used in conjunction with other energy storage technologies ...

For example, ceramic disk capacitors may have lead spacings of 7.5mm or 10mm, and wound capacitor technology may use lead spacings of 10mm to 37.5mm . In general, the lead spacing is selected based on the specific requirements of the application and may be chosen to comply with specific standards or regulations.

If the metal experiences too much strain during stamping, especially at edges or bends, tensile cracks can easily result. Excessive shape changes may exceed the ductility of the metal. When metal is subjected to uneven strain distribution during stamping, excess metal material may be produced in local areas, causing wrinkles or unevenness. 2.

It''s to space the capacitor up off the board so that undue stress is not placed on the ends of the capacitor (for example, if the lead spacing in the board holes is not exactly the same as the lead spacing on that particular capacitor, or if the thermal coefficient of expansion is different from that of the PCB).
The energy is stored at the surface of the electrostatic double-layer capacitors (EDLCs) (Fig. 4.6).As compared to solid-state capacitors, bulk power can be stored across these capacitors and can store bulk energy. However, the stored energy is still less than 10 Wh/kg.Wh/kg.
