Hello, I am from Indonesia. I would like to ask about ordering 10 sets of the product shown in the attached picture below.

Based on the product specifications listed in DigiKey store, does this mean I need to purchase 10 each of BU-21CPN and 10 each of BU-21CPS?

Hello nicomaruli,

Welcome to the DigiKey TechForum.

The part numbers [BU-21CPN](https://www.digikey.com/en/products/detail/mueller-electric-co/BU-21CPN/304407) and [BU-21CPS](https://www.digikey.com/en/products/detail/mueller-electric-co/BU-21CPS/2687992) are both sold individually.

So you can order a quantity of 1, for each of these part numbers.

If you want to order 10 of each, you can do that also.
