3 MEAL OXIE VARISORS NR PRECAUIONS AN GUIELINES 1. he performance of varistors may deteriorate, the inside elements may be damaged, and they cause the varistors to smoke or catch fire, if the following precautions are not observed. (1) o not use varistors in places whose temperature exceeds their rated operating temperature due to direct sunlight or heating objects. (2) o not use varistors in a humid place directly exposed to the weather or steam. () o not use varistors in places filled with dust, salt-mist or corrosive gas. () Apply soldering conditions within the limits prescribed in the catalog or product specifications. For surface mount varistors, use flux with a halogen content of less than 0.2 wt.%. o not use strong acid flux. () o not use solvents such as thinner and acetone which dissolve or make the exterior covering of varistors deteriorate. Ultrasonic cleaning shall be so set that the vibration can not travel the assembly boards. (6) o not expose varistors to intense vibration, shock (drop shock ets.) or pressure making the exterior covering or inside element crack. (7) o not apply high voltage exceeding the rated maximum applying voltage to varistors. In the case of automotive jump starts, however, use the varistors within short-term allowable voltage limits prescribed in the catalog. If voltage wave form is not complete C, a maximum value of peak voltages shall not exceed the rated maximum applying voltage. (8) o not apply peak currents exceeding the rated maximum energy. (9) hen peak currents are repeatedly applied to varistors,do not exceed the pulse life time ratings prescribed in the catalog. () hen peak currents are interrnittently applied to varistors at short intervals, do not exceed the rated wattage. (11) Using varistors in circuits whose frequency exceeds 1kHz may damage their elements by heatgeneration due to dielectric loss. (12) In the case of coating or molding varistors with resin, do not use the resin which makes the varistors deteriorate. (1) o not install varistors in places near by flammable substances. 2. Varistors may blow up, if the following precautions are not observed. (1) o not use varistors in circuits applied peak currents exceeding the specified limits. (2) o not exceed the rated maximum applying voltage.. Varistors do not function but damages devices, if the following precautions are not observed. (1) Hold the root of the varistor lead when bending or cutting the lead. (2) he lead close to insulation cover shall not be bent or applied to outer force. () hen soldering the lead, do not damage a solder material and insulator fabricating the varistor. CA. No. E06J

4 MEAL OXIE VARISORS NR PRECAUIONS AN GUIELINES () Put the proper volume of solder (the height of fillet) on pc boards for installing surface mount varistors, because it directly affects the installed varistors. he design of copper pad pattems and dirmensions should be set so that the proper volume of solder can be provided. () hen mounting surface mount varistors on the pc board, the improper soldering temperature and time out of the limits may reduce the adhesive strength of their terminals. (6) hen cutting off a multi-board to make individual units, curving or twisting the board may make the varistors crack. Appropriate tools should be used to cut it off.. he following preventive measures should be made for avoiding unexpected accident. (1) hen using a varistor in between circuits, connect an earth leakage breaker (ground-fault circuit interrupter) or current fuse in series with the varistor. (2) hen using a varistor in between a circuit and ground, connect an earth leakage breaker (ground-fault circuit interruper) or both of a current fuse and thermal fuse in series with the varistor. Also, in case of excessive voltage due to ground short circuit accident, use the varistor with the rated voltage higher than the excessive voltage.. Store varistors at a temperature of to + C and a relative humidity of less than 7%. Avoid storing in environment of rapid changes in temperature, direct sunlight, corrosive gas or dust, and store with the varistors packaged. 6. Follow stafety standards such as Electrical, UL, CSA and so forth, which specify the use of varistors. 7. Catalogs Specifications in catalogs may be subject to change without notice. Performance test data in the catalogs show typical values, which are not assured in the catalogs. CA. No. E06J

42 NR SE SERIES New! hen the surge energy much higher than the rated maximum energy is applied to the varistors, it may blow up and catch fire. Our newly developed NR SE series is to prevent from being caught fire even very high surge energy is applied. hus electric appliance using our NR SE series can be much safer. Features Newly developed non-flammable material (Harogen Free) is used for outer coating. he new outer coating will meet UL flammability test. At the over voltage test, the new material shall deter burning caused by the high temperature, arc and the large surge current when NR shall blow up. General specifications are same as that of V series, large surge capability NR. Applications Protection for semiconductors from over voltage. Protection for electronic instruments from lightning surge. Absorption of on-off surge from motors and relays..
