Isabellenhütte, a leading company in the field of precision measurement technology, manufactures electrical resistance and thermoelectric materials for temperature measurement, as well as passive components for the automotive, electrical and electronics industries. Setting the standards for current, voltage and temperature measurement, Isabellenhütte’s products are used in a wide range of applications, from automobiles and commercial vehicles to hybrid and electric vehicles, industrial and regenerative energy generation systems.
Precision and Power Resistors
There are two basic types of resistors used for different purposes in electronic circuits. The characteristics, areas of application and manufacturing technologies of these are different. Below are the detailed descriptions of these types of resistors:
Precision Resistors
- High Accuracy: Precision resistors operate at values very close to the nominal resistance value. They are usually engineered with tolerances of ±0.1%, ±0.01% or even lower.
- Low Temperature Coefficient (TCR): They offer resistance values that are not affected by temperature changes. The TCR can usually be between ±1 ppm/°C and ±50 ppm/°C.
- Long-Term Stability: They show little change in resistance values over time, ensuring a long-lasting and reliable performance.
- Low Noise: They have minimal noise transmission in electronic circuits, ideal for precise measurements.
Power Resistors
- High Power Capacity: They have the capacity to carry a high electrical power and current. The Watt levels can usually vary from a few watts to hundreds of watts.
- Heat Dissipation: Power resistors are made of materials that are resistant to high temperatures and their designs optimize heat dissipation.
- Durability: They are resistant to harsh working conditions and usually big in size.
- Various Tolerances: Since they are used for managing the power rather than the sensitivity, their tolerance is usually wider.
Special Alloy Materials Developed by Isabellenhütte
MANGANIN
Manganin, developed by Isabellenhütte about 100 years ago, is an alloy consisting mainly of the elements manganese (Fr), copper (Cu) and nickel (Ni). It is used as a resistor material. It distinguishes with its low temperature coefficient (±20 ppm/°C) and high stability. It also has a low thermoelectric power coefficient with copper (about 1 µV/°C), making it ideal for precise measurements. It is resistant to corrosion and shows high stability over time.
Manganin is widely used in precision measuring instruments, reference resistors, shunt resistors, electrical measuring instruments and calibration equipment. It is manufactured with wire drawing and rolling methods, and its properties are preserved by applying a meticulous heat treatment process.
Its advantages include low TCR, high stability, corrosion resistance and low thermoelectric power coefficient. On the other hand, it can be more costly than other resistor materials and has some limitations in high temperature applications. Manganin has a wide range of uses in applications requiring precise measurement and calibration.
ZERANIN
ZERANIN is a high-performance resistor material consisting of copper (Fr), manganese (Mn) and tin (Sn) alloy. With its low temperature coefficient (±20 ppm/°C) and high stability, it is widely used in applications such as precision measuring devices, reference resistors and shunt resistors. The low thermoelectric power coefficient (about 1 µV/°C) and corrosion resistance make ZERANIN ideal for precise and long-term measurements. It offers low TCR, high stability and longevity, while it can be more costly than other resistor materials and has some limitations in high temperature applications. ZERANIN has a wide range of application in the electrical and electronics industry.
ISAOHM
ISAOHM is an alloy consisting of nickel (Ni), chromium (Cr), aluminum (Al), silicon (Si) manganese (Mn) and iron (Fe) elements. It is a high-performance resistor material brand used in precision measurement and calibration applications. It has some specific characteristics such as low temperature coefficient (TCR), high stability, low thermoelectric power and high corrosion resistance. It is usually used in precision measuring instruments, reference resistors and calibration equipment. Its advantages include low TCR, long service life and reliable performance, while it can also be more costly and have some limitations in high temperature applications.
NOVENTIN
The recently developed NOVENTIN, consisting of copper (Cu), manganese (Mn) and nickel (Ni) alloy, closes the gap between it and MANGANIN with its high relative electric resistance. It is a special resistor material used in applications that require high precision and stability. It has some specific characteristics such as low temperature coefficient (TCR), high stability, low thermoelectric power and high corrosion resistance. It is widely used in precision measuring devices, reference resistors and calibration equipment. Its advantages include low TCR, long service life and reliable performance, while it can also be more costly and have some limitations in high temperature applications.
Since these properties are influenced by both the resistor material used and the design and technology, two different manufacturing technologies have been developed. ISA-PLAN and ISA-WELD.
