Standard resistors that meet the demand for high current/low resistance values! Resistors with excellent long-term stability.
The "LSR Series" is a standard resistor developed to meet the demands for high current and low resistance values. The resistive element uses carefully selected metal foil, achieving a low temperature coefficient and excellent long-term stability. Additionally, to suppress internal temperature rise, the structure allows for high power measurements using an aluminum perforated plate in the housing. Since it is an air-type that does not require auxiliary equipment such as oil baths or cooling devices, it can be used in a wide range of applications including high-precision measurements, in-house calibration, and reference for precision power supplies. 【Features】 ■ Capable of high power measurement ■ Excellent long-term stability ■ Extremely low temperature coefficient despite low resistance in an air-type ■ Structure that suppresses self-heating due to load ■ Calibration certificate and test report traceable to NMIJ included *For more details, please refer to the PDF document or feel free to contact us.
