5 / 7 page Multilayer Varistors Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use. Should a safety concern arise regarding this product, please be sure to contact us immediately. Specifications ÑÑÑ To meet the specified value. EZJZ Series: ±0.1 %/¡C EZJS Series: ±0.3 %/¡C EZJZ Series: ±20 % EZJS Series: ±10 % n Performance Characteristics l Electrical Test Method Unless otherwise specified all test and measurements shall be made at a temperature of 15 to 35 ¡C and at a relative humidity of 45 to 75 %RH. If results obtained are doubted a further test should be carried out at a temperature of 20± 2 ¡C and a relative humidity of 60 to 70 %RH. The maximum DC voltage that can be applied continuously in the specified operating temperature. The voltage between two terminals with the specified measuring current CmA DC applied is called Vc or VcmA. The measurement shall be made as fast as possible to avoid heat affection. Capacitance shall be measured with the specified measuring frequency, 0.2 to 2.0 Vms., 0V bias and 20 ¡C. The Maximum current within the varistor voltage change of ±10 % when a standard impulse current of 8/20 ms is applied two times with an interval of 5 minutes. The maximum ESD within the varistor voltage change of ±30% when impressing 10 times of ESD (five times of positive- negatives for each polarity) which is based on IEC61000-4-2 Coefficient indicating dependency of V-I characteristics on temperature. This is shown by the change of VcmA per ¡C at the ambient operating temperature. This is shown by the maximum capacitance change at the ambient operating temperature. Characteristics Standard Test Condition Maximum allowable Voltage Varistor voltage Capacitance Maximum peak current Maximum ESD Temperature coefficient Varistor Voltage Temperature coefficient capacitance Specifications Approximately 75 % of the terminals shall be covered with new solder uniformly, No remarkable mechanical ÆVc/Vc < ±10 % l Mechanical requirements Test Method After securing the specimen by the body with tweezers and dipping in to the specified soldering flux, the specimen shall be completely immersed into a soldering bath having a temperature of 235±5 ¡C for 4±1 seconds. And then the specimen shall be visually examined. Use the specified soldering flux and solder following: Soldering Flux: Ethanol solution of rosin about 25 % by weight Solder: Eutectic solder (Sn 63 : Pb 37) After preheating the specimen according to the following conditions in Table-1, the specimen shall be completely immersed into a soldering bath having a temperature of 270±5 ¡C for 3±0.5 seconds. And then be stored at room temperature for 24±2 hours. Thereafter, the change of Vc and the mechanical damage shall be examined. Characteristics Solderability Resistance to soldering heat Step Temperature Period 1 080 to 100 ûC 300 to 360 s 2 150 to 200 ûC 300 to 360 s |
