(measured from -55C to 125C referenced to + 25C) TYPICAL APPLICATION RL Series is an innovative method of providing low inductance resistors in a cylindrical ceramic body and is increasingly replacing the moulded version. The resistive element consists of a flat metal band which is spot welded to the copper terminals before encapsulation. The resistors are finding increasing use in industrial applications where pulse rating and ability to absorb high inrush current are required. Another important application is Current Sensing in applications which include switching and linear power supplies, instruments & power amplifiers.
