The difference between these three models CBB65/CBB60/CBB61

How do you say, when operating Taobao shop, many customers who know little about the capacitor will ask me what is the difference between these three models. So here, I briefly explain briefly, the three models are the same and different.

From the names, everyone can see that there is an identical place in their names: "CBB". In fact, CBB65, CBB60, and CBB61 belong to the family of polypropylene film capacitors. Also use the thickened metallized zinc-aluminum film as the electrode and medium. The coiled capacitor core is placed in the housing and poured into oil or epoxy for vacuum (to prevent film oxidation). Capacitor performance is better, capacity is more stable!

Now let's talk about their differences. The CBB65 capacitor has an aluminum shell and the inside is made of high-purity castor oil to maintain the vacuum and has a cylindrical shape. CBB60 and CBB61 are made of flame-retardant epoxy resin to keep the capacitor cores. Although the shells are all PVC shells, CBB60 is cylindrical and CBB61 is square.
