Design Considerations for Capacitor Installation

Forcibly inserting a capacitor into a PC board when the hole spacing doesn''t exactly match the terminal spacing will damage the lead wires or terminals, the capacitor seal and the internal connections to the element. This mechanical stress may cause sealing failure, electrolyte leakage and electrical failures such as a short circuit (non-solid).

How to use the Lead Terminals of Supercapacitors

Provide the following space above the rubber part of the lead terminals of the capacitor. (Do not attach the capacitor directly to the board, but leave a space.) Do not wire a circuit pattern below the seal plate of the capacitor. When wiring near the capacitor, ensure at least 1 mm (2 mm if possible) of space between the circuit patterns.

The example shown in the picture and the table demonstrate how one MLSH capacitor can replace a parallel bank of four D-sized wet tantalum capacitors. The table compares one MLSH (2200 µF @ 40 Vdc) with a parallel bank of 4 x (1000µF @ 40 Vdc) wet tantalum caps. The high temperature capacitance ( @ 125 °C) of the wet tantalum bank is much higher, but as shown,

What is the Standard Lead Spacing for Capacitors?

Often, radial film capacitors with small lead spacings use a 5 mm standard. There is, however, no standard lead spacing for capacitors of other types. Lead spacings for ceramic disk capacitors, for example, can range from 7.5 mm to 10 mm, while lead spacings for wound capacitors can range from 10 mm to 37.5 mm. It is usually decided on the lead

Snap-in Aluminum Electrolytic Capacitors

In aluminum electrolytic capacitors, electrolyte is injected inside the capacitor, and the sealing material is tightened with the aluminum case to maintain a seal. However, as the electrolyte evaporates through the molecules of the sealing material, the amount of electrolyte inside decreases over time. As a result, the capacitance of the capacitor decreases and the

3 FAQs about [Lead capacitor sealing picture]

What is a foam pad on a capacitor?

Large, through-hole capacitors (typically electrolytic) sometimes have a foam pad on the bottom like the one in this picture: What is the pad for? I'm pretty sure it's not foam, but plastic or rubber. Well, foam is textured plastic. I used the word foam because it definitely has some give to it if you push it.

How do you Mark aluminum caps?

Aluminum caps can be marked in a number of different ways. Radial, through-hole cans will commonly have a line down the negative side of the body, with the negative lead being shorter as well. Radial, surface mount cans will have a colored portion on the top indicating the negative pad.

Do polarized capacitors have a designator on them?

Polarized capacitors will always have some sort of designator on them identifying polarity. This is important, because hooking one up backwards can be dangerous. Aluminum caps can be marked in a number of different ways.
