8533.21.00.50 - Single-in-line

This HTS subcategory encompasses single-in-line (SIP) fixed electrical resistors designed for a power handling capacity not exceeding 20 watts. These components are characterized by having more than two leads, typically arranged in a single row, and are often referred to as resistor networks. They are integrated into electronic circuits to control or limit electrical current and voltage.

Within the broader category of other fixed resistors for a power handling capacity not exceeding 20 watts, this classification is specifically distinguished by its single-in-line packaging. It differs from its sibling category, 8533.21.00.60, which covers dual-in-line (DIP) resistor networks, identified by leads arranged in two parallel rows. The sibling category 8533.21.00.70 represents any other fixed resistors at this power level that do not fall under the SIP or DIP configurations.

As a leaf node in the HTS classification, there are no further subcategories under 8533.21.00.50. Therefore, classification into this subcategory relies on the definitive presence of a single-in-line lead arrangement and a power handling capacity of 20 watts or less, excluding heating resistors. Examples include SIP resistor arrays used in memory modules or as pull-up/pull-down resistors in various electronic assemblies.
