CH-12 by Bel Signal Transformer is a common mode chokes / filters designed for reliable performance in electronic applications. It is widely used in industrial, automotive, and power management systems.

Inductors, coils, and chokes are various names used to refer to products that store energy in the form of a magnetic field. The vast majority of the products found in this category are simple fixed-value devices, though adjustable types, products for wireless power transmission, and magnetically-coupled inductor arrays are also included. Note that the coupled-inductor devices found within this product family are characterized by having multiple identical windings sharing a common magnetic core; similar products with non-identical windings are more commonly described as transformers, and are categorized as such.
