Unlike the battery, a capacitor is a circuit component that temporarily stores electrical energy through distributing charged particles on (generally two) plates to create a potential difference. A capacitor can take a shorter time than a
Why does the capacitor need to be small in RC filter
In this range, keeping the capacitor value lower (i.e. 10 uF instead of 22 or 100 uF) will allow you to keep the part physically smaller (which is good if you need to fit it on a board with a bunch of other stuff), and/or allow

6 Frequently Asked Questions about “Why do capacitors need to be tinned ”
Why are capacitors important?
Capacitors are a common component in most electronic devices and are most importantly involved in energy storage. The development of capacitors is therefore important in order for technological advancements of batteries.
What happens when you tin a wire?
When you tin wires, the tin creeps into the insulation, creating an extra-hard bit (solder + wire + insulation), which acts as a fulcrum onto the bit just past it (only solder + wire), which is weaker and now operates mechanically much more like a single conductor than strands.
Do you tin copper wire?
In dry environments, do not tin, as the other answers say. In damp and specifically corrosive (salt water) environments, un-tinned wire is susceptible to corrosion, which creeps along the wire, so you can't just cut a foot off and expose bare copper) while tinned wire ends remain usable. Sometimes called "black plague".
How does a capacitor work?
The electrons will build up on one plate of the capacitor while the other plate will in turn release some electrons. The electrons can't pass through the capacitor though because of the insulating material. Eventually the capacitor is the same voltage as the battery and no more electrons will flow.
Why should you not tin wires?
On the top one spot, with gold star by the way, of the list of reason to NOT tin wires is fatigue.
Why do chip capacitors fail during the cooling cycle?
Chip capacitors are even more vulnerable to failure during the cooling cycle, as negative temperature gradients cause primarily tensile stress. Cooling must therefore be gradual and uniform, with no localized forced cooling or contact of the chip with any efficient heat sink.
