Precautions for Use 1/40s1.2/50s 50% 3kV d.c.1cm Impulse withstanding voltage is specified for waveform of 1/40s or 1.2/50s as a standard. Please inquire of us in advance when using other than the standard waveform, since the specified value may change, depending on time constant or length of wave tail. Use the components under less dusty places, as continual applying of high voltage makes dust adhere to the surface of the resistors and causes surface leakage and corona. Also periodic cleaning of the surface of resistors is needed. Use them at 50% or under of the rated power for stable use for a long time. Do not touch the resistors with high resistance value by hand to prevent surface-leakage current. Set the products away from near electric conductors 1cm or over per 3kVd.c. to avoid occurrence of corona and short-circuit by discharge, if there are electric conductors near to. Ceramic is used for the core of these resistors. Pay attention to the handling as the characteristics may be deteriorated by damage and inner crack when they are fallen or shocked. In case of using in oil, inquire of us in advance. Take care that the resistors may become instable in resistance value by absorption of humidity when they are stored or used in high humidity environment.
