NF13 PTC Ni-Fe Alloy High Nickel85-95 Welding Wire for Power Regulation, Resistivity 0.13

The product exhibits a resistivity of 0.13 at a temperature of 20°C, with a tolerance range of ±0.02.

PTC Alloy wire has medium resistivity and high positive temperature coefficient of resistance. It is widely used in various heaters. It can automatically control temperature and adjust power by keeping constant current and limiting current. PTC alloy has many advantages such as automatic temperature control, automatic power regulation, constant current, current limiting, energy saving and long practical life.

Thermistors made from PTC alloy resistance wire can be connected in series in a circuit to suppress excessive current, providing protection for components. They are widely used in power equipment such as chargers and transformers.

We perform two sampling analyses during production and conduct a finished product inspection upon completion, ensuring the chemical composition, diameter, resistivity, and temperature coefficient of the product meet the requirements. Compared to similar products, we achieve a higher yield rate and greater usage stability, minimizing potential quality issues during use.
