Product Description

6J8/6J8P/6J8X Precision Resistance Wire High Electrical Resistivity and Low TCR for Consistent Performance in Electronic Devices

6J8/6J8P/6J8X Precision Resistance Wire refers to a type of precision resistor wire commonly used in applications that require stable and accurate electrical resistance. This wire is often made from a Manganin-type alloy, which includes a mix of elements such as Copper (Cu), Nickel (Ni), and Manganese (Mn), though exact compositions can vary slightly across the different grades or designations (6J8, 6J8P, 6J8X).

6J8/6J8P/6J8X Precision Resistance Wire is a high-performance material used in applications requiring precise and stable electrical resistance, with low temperature dependency and high durability. It is ideal for calibration, current sensing, and precision measurement applications across scientific, industrial, and high-tech fields. The various grades (P and X) offer enhanced properties for more demanding or specialized applications, ensuring accuracy and long-term reliability.

Note : The effective cross-sectional area of strip is the product of its width and thickness multiplies the following coefficient: Width<10mm, multiplied by 0.98; Width≥10mm, multiplied by 0.94.

Some key features of 6J8 include:

High Resistivity:

6J8 wires are typically used in resistors or current-sensing applications where stable, high resistivity is required.

Low TCR:

The wire’s low temperature coefficient ensures that resistance remains stable across varying temperatures, which is vital for precision instruments.

Corrosion Resistance:

The alloy provides resistance to oxidation and corrosion, even in harsh or humid environments, ensuring the longevity and accuracy of the components.

Mechanical Properties:

The wire has good tensile strength and can be drawn into fine wire forms for specific applications like precision resistors, shunt resistors, and heating elements.

Application

Precision Resistors:

Used in standard resistors for calibration and reference, ensuring high accuracy.
