8533.21.00.40 - Cylindrical leadless resistors (including metal film, metal oxide and thick cement film)

This HTS category, 8533.21.00.40, encompasses cylindrical leadless electrical resistors designed for a power handling capacity not exceeding 20 watts. These resistors are characterized by their cylindrical form and the absence of external lead wires for connection, relying instead on direct contact. This description includes common types such as metal film, metal oxide, and thick cement film resistors that fit this physical configuration and power rating.

Distinguishing this category from its sibling, 8533.21.00.30, is crucial. While the sibling specifically covers "flat resistor chips," this category focuses on resistors with a cylindrical body. The absence of leads is a key defining feature for both, but the geometric shape differentiates them. This distinction is based on distinct manufacturing processes and intended mounting methods, even though both are fixed resistors with a power capacity under 20W designed for surface mounting.

As this classification represents a leaf node within the HTS database, there are no further subcategories. Therefore, the focus for classification within this code is on verifying that the cylindrical leadless resistor possesses a power handling capacity not exceeding 20 watts and is intended for surface mounting. Examples include cylindrical chip resistors where connection is made directly to the termination pads on the component body.
