28 Gauge Enameled Copper Wire
- The bare wire diameter is approximately 0.321mm.
- The cross-sectional area is approximately 0.081mm².
- It uses high-purity oxygen-free copper wire as the core, with an outer layer coated with insulating enamel.
- The safe current-carrying capacity at room temperature is about 0.3-0.5A.
28 gauge enameled copper wire refers to 28awg enameled copper wire under the American Wire Gauge system. Its key specifications are as follows:
Due to its small wire diameter and low current-carrying capacity, it is mainly used for winding micro inductors, small transformers, micro motors, and precision sensors.
Why choose 28 Gauge Enameled Copper Wire?
The logic for choosing 28 gauge enameled copper wire is straightforward, with the core principle being “equipment requirements determine specifications.” Industry practice is to complete equipment design first, then procure matching wires; rather than procuring wires first and then designing equipment to fit the wires in reverse. If your equipment is of a small, precision type, it may require fine-gauge wires like 28 gauge enameled copper wire. As for the specific choice between AWG26, AWG27, AWG28, or AWG29, it ultimately depends on the actual conditions of the equipment.
Application Analysis of 28 Gauge Enameled Copper Wire
