The company's full complement of resistor construction includes wirewound, wire element, thick film, and ceramic composition. Why are some Old English suffixes marked with a preceding asterisk? However this is design dependent and it may still be wise to spec the resistor for the full voltage if it is somewhere in the design where there is a chance that it can be exposed to the full voltage in some unexpected condition. MAXIMUM RATINGS (TA = 25°C unless otherwise noted) Rating Symbol Value Unit Collector-Base Voltage VCBO 50 Vdc Collector-Emitter Voltage VCEO 50 Vdc Collector Current IC 100 mAdc Total Power Dissipation @ TA = 25°C (Note 1.) Careful consideration of these important factors should help lead you to the selection of the proper chip resistor component for your design. Chip Resistor - Surface Mount Share Resistors provide opposition to current flow, in a manner that is proportional to the electric potential (voltage) imposed across them, and which is ideally unaffected by signal frequency or changes in temperature. If the resistor is in series, the voltage rating doesn't necessarily need to be quite as high - it will depend on the current through the resistor. However the small size of SMT resistors makes the figures difficult to read. High voltage chip resistors are available in resistance values from 5 kΩ to 1 GΩ with ratings from 600 V to 5 kV. Overload Current (Jumper) 2A Max. The 230 V in might actually be 240 V, so the peak would be 340 V. That still gives you 260 V of margin.
