8533.10.00.57 - Having more than two leads (resistor networks)

This HTS category, 8533.10.00.57, specifically covers fixed electrical resistors that are constructed using carbon composition or film-type resistive elements, and importantly, possess more than two leads. These are often referred to as resistor networks, where multiple resistors are integrated into a single component with a shared or common lead. The defining characteristic is the presence of multiple connection points beyond the typical two terminals found in standard single resistors, enabling more complex circuit integration.

Distinguishing this category from its sibling, "Designed for surface mounting (SMD) by contact," is crucial. While both fall under fixed carbon resistors, composition or film types, the distinction lies in the mounting method and lead configuration. Resistors classified under the sibling category are specifically designed for automated surface mounting technologies, typically featuring flat pads or short pins for direct soldering onto a printed circuit board's surface. In contrast, 8533.10.00.57 focuses on the functional characteristic of having more than two leads, regardless of whether they are through-hole or surface-mount in design, as long as they meet the "more than two leads" criterion.

As this classification represents a leaf node within the HTS database, there are no further subcategories. Therefore, practical classification relies on the precise identification of the component's construction (carbon composition or film) and the confirmation of its lead count exceeding two. Examples include thick-film resistor networks used for pull-up/pull-down functions or as precision resistor arrays within integrated circuits.
