Snap-in Aluminum Electrolytic Capacitor is designed for easy mounting on a printed circuit board. Pins under snap-in capacitors are to hold the component in the place on the PCB.
If you are wondering what kind of capacitors you are looking for, here are some of the products where Snap-in E-cap can be found.
Typical application where you can found Snap-in be used are converters, solar inverters, UPS, power supplier and automotive.

JNE & JNC are our two most popular items for snap-in options. We are also having better price for these two types of capacitors.
Feel to check out our datasheet below or send us your RFQ list for quote.

Basic construction:
1, Two pieces of foils interleaved with an absorbent paper build up the key element of an Aluminium Electrolytic Capacitor, and all these materials should be wound tightly into a cylinder shape
2, The positive foil, or the anode foil are all made from pure aluminium foil. The aluminium oxide dielectric has been formed electrolytically on the surface.. 
3, The foil has been etched to make the effective surface area more larger, and the area of the anode is usually 30–100 times larger than the plan area of the foil.

Figure: How dielectric structure works in an Aluminium Electrolytic Capacitor ?
4, The other plate is a combination of high-absorption paper impregnated with an electrolyte, in contact with a cathode foil. 
5, The electrolyte is there to make good contact with the anode, by permeating its etched structure, and also to repair any flaws in the oxide layer when the capacitor is polarised. 
6, The function of the aluminium cathode foil is to reduce the series resistance of the capacitor by making contact with the paper over a wide area.
