IRC Resistors – Passive Components
IRC (International Resistive Company) is a manufacturer of resistive products such as resistors, potentiometers, and precision resistive networks. IRC has been an innovative leader in the design, development and manufacture of resistive components for more than 70 years. IRC is known as a new products innovator and a worldwide quality supplier with focus on resistor application solutions. IRC’s products include surface mount resistors, resistor networks, high voltage resistors, wirewound resistors current sense resistors and more. IRC is a preferred supplier of resistive products to the automotive, telecommunications, computer, instrumentation, military medical and industrial process control industries.
IRC designs and manufactures electronic components for customers across defense and aerospace, medical, transportation, energy and industrial electronics markets. Key applications are circuit protection, power and energy management, medical device equipment and signal conditioning. in 2017, IRC was acquired by TT Electronics, a global provider of engineered electronics for performance-critical applications. Following the acquisition, IRC's product lines and operations were integrated into TT Electronics' broader portfolio of electronic components. Additionally TT IRC has one of the widest ranges of MIL approved resistors in the market. Products include: fixed resistors – current sense, high power, precision, fusible, flameproof, high voltage/value, surge/pulse, general purpose and dividers.
IRC was known for its innovative designs and advanced manufacturing processes, which allowed the company to produce resistive components with exceptional performance characteristics such as precision, reliability, and stability over a wide range of operating conditions.
Products
-
Resistors: IRC produced a wide range of resistors, including fixed resistors, precision resistors, and power resistors. These resistors were used in various electronic circuits for applications such as voltage division, current limiting, and signal conditioning.
-
Potentiometers: IRC manufactured potentiometers, also known as variable resistors or pots, which are used to control the electrical resistance in a circuit. These components were commonly found in audio equipment, industrial controls, and instrumentation.
-
Resistive Networks: IRC developed precision resistive networks, which are arrays of resistors integrated into a single package. These networks provided accurate and stable resistance values for applications requiring precise voltage or current division.
