Note 2: Overload voltages are dc or ac peak values. Note 1: Termination pitch dimension P is measured between the lead centres at 1mm from the resistor body.

Capacitor Discharge Resistors CDR Series Overload Performance Construction CDR is a high voltage planar style resistor. Pd/Ag terminations are printed and fired onto the front face of a 96% alumina substrate. A resistor material is printed with a high voltage design between the terminations and after firing gives an excellent high voltage performance. This is then laser adjusted to target value before being coated in a glass material. Hot tin dipped copper wire terminations are then fitted using Sn/Ag/Cu solder. The product is 100% measured for resistance value. It is cleaned of all flux residues and ionic contamination in order to ensure compatibility with capacitor dielectric fluid applications. Marking Type and resistance value are legend marked on the front of the component. Termination Lead Pull Strength Each termination lead shall withstand a tensile load of 1kg at an angle of 90° to the plane of the resistor, with no mechanical failure admitted, such as breaking of the resistor substrate or shearing of the termination lead wire or solder. Solderability The terminations meet the requirements of IEC 115-1 Clause 4.17.3.2 CDR01 CDR02 CDR03 CDR04 CDR05 CDR06 Performance Data Requirement Typical Load at rated power in air (1000 hours at 70°C) ΔR% ≤1 <0.25 Load at rated power in fluid (1000 hours at 70°C) ΔR% ≤1 <0.25 Derating from power at 70°C Zero at 155°C Vibration (9-200Hz @ 5mm / 50ms-2, 10 sweeps @ 1 octave / min, 3 axes) ΔR% ≤1 <0.25 Termination pull strength (applied at 90° to plane of body, no damage visible) kg ≥1 >4 Overload in dielectric fluid (90s at 25°C, see Overload Ratings graph) ΔR% ≤0.5 <0.1 Make Possible 07.14 General Note TT Electronics reserves the right to make changes in product specification without notice or liability.
