[Standard Resistor] Outstanding low temperature characteristics! Usable in a wide range of fields such as precision measurements in work environments.
The "ASR Series" is a highly stable standard resistor that employs our unique high-stability, low-resistance temperature coefficient Ni-Cr alloy foil as the resistance element. The excellent resistance temperature coefficient of the metal foil allows for use in air without the need for expensive and complicated temperature control equipment such as oil baths, making it suitable for precise measurements and calibrations in various fields. The housing consists of a compact and robust body and cover, designed to protect the terminals from damage and facilitate storage. 【Features】 ■ Long-term stability is high, at 3ppm/year or less after the first year. ■ The resistance temperature coefficient is low, at 0.2ppm/°C or less between 0°C and 50°C. ■ A comprehensive lineup of resistance values ranging from 1Ω to 10MΩ. ■ Non-wound structure provides excellent AC characteristics. ■ Compact and robust design that considers operability and storage. *For more details, please refer to the PDF document or feel free to contact us.
