Eliminates sparks between governor contact and commutator and brushes; absorbs noise in micro motors. Large net voltage non-linear coefficient ( ) of 3 to 7, and large ele ctrostatic capacitance of 10 to 150 nF. Noise can thus be absorbed over a wide range of frequencies.

Circuit Design Verification of operating environment, electrical rating and performance 1. A malfunction in medical equipment, spacecraft, nuclear reactors, etc. may cause serious harm to human life or have severe social ramifications. As such, any varistors to be used in such equipment may require higher safety and/or reliability considerations and should be clearly differentiated from components used in general purpose applications. Operating Environment precautions Precautions 1. Varistors should not be used in the following environments : 1Environmental conditions to avoid a.exposure to water or salt water. b.exposure to water or salt water.exposure to moisture or condensation. c.exposure to corrosive gases (such as hydrogen sulfide, sulfurous acid, chlorine, and ammonia). 2. Soldering Soldering Be sure to do pre-heating sufficiently so that the difference between a soldering iron and ring varistors in temperature should be 150 or less. Ring Varistors are susceptible to thermal shock when exposed to rapid or concentrated heating or rapid cooling. Therefore, the soldering process must be Precautions conducted with a great care so as to prevent malfunction of the components due to excessive thermal shock. Use a 30W soldering iron with a maximum tip diameter of 3.0mm. The soldering iron should not directly touch the products. Technical Soldering Refer to individual specifications. considerations This catalog contains the typical specification only due to the limitation of space.
