Product Introduction
main features
1. Compared to precision plug-in resistors and wire wound resistors, it has a compact and exquisite appearance. If it is used for some small-sized products, it will save a lot of space. The consistency of soldering on the surface mount machine is good, and the efficiency is high.
2. The highest accuracy can reach 0.01%, and the lowest temperature coefficient can reach 5PMM.
3. The size range is wide, with a minimum of 0201 and a maximum of 2512.
4. High cost-effectiveness, about twice as cheap as cylindrical metal film resistors of the same specifications, and even more in some specifications.
