precision wirewoud resistor

precision wirewoud resistor are designed for critical applications that require very accurate and stable resistance values. They are avaliable in a subminiature series. These precision resistors are non-inductively wound on molded bobins. The solderable and weldable leads are tinned copper. Internally, they are welded for gighest precision and reliability. All precision resistors are aged to insure stability. A protective coating insulates the windings and protects the welds. The bobbin is encapsulated using a specially formulated epoxy so temperature expansion coefficients of all materials are cloely matched.
