If you re talking about capacitors like these then snap in refers to the way the capacitor leads are formed.
Snap in capacitor soldering.
Alternate back and forth melting the solder while pulling on the capacitor.
Contact with the body can cause the sleeving to crack or melt.
The safety vent on the base provides overload protection.
This video highlights the advantages of nichicon s wide selection of snap in capacitors and why they re a fantastic fit for ac servomotors inverter controls.
To use them make sure your pcb footprint is correct including both the lead spacing and the finished hole diameter after plating.
Then heat the other leg and wiggle the capacitor some more.
Desoldering snap in capacitors heat one leg of the capacitor until the solder melts all the while pulling on the capacitor.
Snap in capacitors are used in a wide variety of applications because of the many advantages they provide.
When soldering aluminum electrolytic capacitors with a soldering iron the exposure should be limited to 260 c for 10 seconds or 350 c for 3 seconds.
Some tips on how to desolder capacitors from a motherboard with large ground planes and many layers.
Easy ways how to solder unsolder desolder parts and wires with flux duration.
The aluminum case is fully insulated.
Snap in caps feet are bent like a claw so they can be pushed down and snapped into the holes on the pcb.
They act as little springs to grip the pcb drill holes.
This allows them to stay on the board so you can flip it over to solder.
The marking of the polarity makes installation easy.
