8533.21.00.10 - Dual-in-line package 🖩

This HTS category, 8533.21.00.10, specifically classifies fixed electrical resistors designed for a power handling capacity not exceeding 20 watts, which are intended for surface mounting (SMD) by contact, and importantly, possess more than two terminals. These are commonly referred to as resistor networks, where multiple resistor elements are integrated within a single package to perform various resistance functions in electronic circuits. The "Dual-in-line package" description is a specific form factor that falls under this broader classification of resistor networks with more than two terminals designed for SMD mounting.

Distinguishing this category from its sibling, 8533.21.00.20, is crucial. While both fall under fixed resistors not exceeding 20W and designed for surface mounting, 8533.21.00.10 is exclusively for resistor networks having more than two terminals. The sibling category, "Other (including flat packs)," covers surface-mounted resistors with up to two terminals or those that are resistor networks but not in a dual-in-line package format. Therefore, the key differentiator lies in the number of terminals and the specific package type for resistor networks.

As this is a leaf node, there are no further subcategories. Classification within 8533.21.00.10 is determined by the combination of the resistor's power rating (not exceeding 20W), its surface-mount capability with contact termination, and the presence of more than two terminals functioning as a resistor network, specifically in a dual-in-line package. Examples would include complex resistor arrays integrated into a single SMD component for applications requiring precise resistance ratios or multiple distinct resistance values within a compact footprint.
