B82141A – miniature inductors for output mounting from TDK

Inductance is one of the basic elements in electrical engineering and electronics. Depending on the design features of inductive elements, the purpose and conditions of their use are determined. Inductors for output mounting on a printed circuit board from TDK have been widely used due to the ease of installation, stability of overall dimensions and technical characteristics, high quality and reliability.

The inductance of the B82141A series is an inductor of the SBC type (Small Bobbin Core) with terminals for mounting on a printed circuit board through holes, designed for use as a choke at radio frequencies. The design features of the inductors B82141A are a miniature ferrite core of the coil, winding with enameled copper wire, fire-resistant paint coating of the element.

Appearance and packaging format of the B82141A series inductors

Distinctive features of the B82141A series are: small overall dimensions (this is the smallest series of inductors for output mounting at TDK) - 3.0x6.8 mm (øhL), relatively high rated current, can be used for wave soldering in an automated way. The rated inductance in the series is from 1 to 1000 MCG, the rated current is from 55 to 725 mA.
