The term snap-in is a result of the lead configuration for this type of aluminum electrolytic capacitor. This style is designed for easy mounting on a printed circuit board. At TEDSS, you can look for what you need from one the industries largest inventories of this style of capacitor. Our easy to use website and terrific pricing are why you should make www.tedss.com your first choice when you are looking for electronic components.
Snap-in capacitors are used in a wide variety of applications because of the many advantages they provide. The aluminum case is fully insulated. The marking of the polarity makes installation easy. The safety vent on the base provides overload protection. Snap-in solder pins hold this component in place on the PC-board. They are made in many different case sizes. They have a high ripple current capability.
These are just some of the reasons that make this style one of the most popular of the aluminum electrolytic capacitors. The reason you should visit TEDSS to buy your snap-in capacitors is because you can search for what you need by using a part number, a description or just by using a using our visual search capability to match the picture of the part in stock in TEDSS with the part you need to replace. Our ability to ship the same day, in most cases and our great pricing will help you to see why our loyal customer base is growing every day.
TEDSS inventory, which expands almost daily, gives you the opportunity to buy snap-in capacitors made by the leading capacitor manufacturers and their most recent product offerings. It ranges from 6.3VDC up to 500VDC.

What is a snap-in capacitor?
It is a radial lead aluminum electrolytic capacitor that has SNAP-LOCK terminals. These terminals allow for the capacitor to be locked into place to prevent any unnecessary movement.
What is the difference between snap-in and snap mount capacitors?
There is no difference both terms refer to the same lead style termination.
Why do snap-in capacitors have a vent?
The safety vent on the base of the capacitor provides overload protection.
What is the lead spacing on a snap-in capacitor?
For 2 pin style snap-in capacitors the standard lead spacing for any standard diameter size is 10mm.
Can I increase the voltage rating for the capacitor I need without it causing a problem?
Yes if you are using a capacitor that has a DC voltage rating you can use a capacitor that has a higher rating without it being a problem however when the voltage is increased the size may also increase and that cause create a problem in where the capacitor is being placed in the application. You will need to check the size of both voltage ratings before switching to the higher voltage.
What are the standard temperature ranges for snap-in capacitors?
The most common ranges are:
Why do some snap-in capacitors have 3, 4 and 5 leads?
The additional leads are for physical stability in mounting the capacitor. It is used to ensure correct insertion. It should have no electrical connection.
Is the endurance hour rating important for a snap-in capacitor will operate?
Yes it indicates how long the capacitor with work at maximum efficiency when used at the maximum ambient temperature temperate rating. If the temperature is decreased the lifetime will be extended.
Do I have to use all pins in multi pins snap-in capacitor?
No you don’t. If your capacitor has more than 2 pins, you don’t have to use the other pins. They are only for mounting stability purpose. For any reason you may have, you can bend, remove all other terminals except positive and negative ones.
Where Snap-In capacitors are used?
Some of the most common applications for snap-in capacitors to be used are:
The ability to get a capacitor that can work in high voltage applications such as 400V, 450V and 500V in a compact size is just one of the reasons that this style is popular in these applications. The high reliability and low ESR ratings are also characteristics that make this style the right choice for many design engineers.
