8533.21.00.30 - Flat resistor chips

This HTS classification covers flat resistor chips designed for surface mounting (SMD) and possessing two terminals. These components are fixed resistors, meaning their resistance value is set and not adjustable. They are specifically intended for applications where the power handling capacity does not exceed 20 Watts. The "flat chip" characteristic emphasizes their physical form factor, typically rectangular or square, designed to be soldered directly onto the surface of a printed circuit board without leads.

This category is distinguished from its sibling, 8533.21.00.40, which covers cylindrical leadless resistors. While both are surface-mount, two-terminal, fixed resistors with a power capacity not exceeding 20W, the key differentiator lies in their physical shape. Cylindrical leadless resistors, as described in the sibling, are characterized by their tubular or barrel-like form factor, often with end caps. In contrast, the resistors classified under 8533.21.00.30 are specifically flat or planar in design.

As a leaf node within the HTS, there are no further subcategories branching from 8533.21.00.30. Therefore, the focus for classification within this heading remains on the precise identification of flat resistor chips that meet all the preceding criteria: fixed resistance, power handling not exceeding 20W, designed for surface mounting by contact, having two terminals, and being of a flat chip configuration.
