Multilayer Varistors Performance and Testing Methods Characteristics Specifications Testing Method Standard test conditions Electrical characteristics shall be measured under the following conditions. Temp. : 5 to 35 °C, Relative humidity : 85 % or less Varistor voltage To meet the specified value. The Varistor voltage is the voltage (V C ,or VcmA) between both end terminals of a Varistor when specified current (CmA) is applied to it. The measurement shall be made as quickly as possible to avoid heating effects. Maximum allowable voltage To meet the specified value. The maximum DC voltage that can be applied continuously to a varistor. Capacitance To meet the specified value. Capacitance shall be measured at the specified frequency, bias voltage 0 V, and measuring voltage 0.2 to 2 Vrms. Maximum peak current To meet the specified value. The maximum current measured (Varistor voltage tolerance is within ±10 %) when a standard impulse current of 8/20 µ seconds is applied twice with an interval of 5 minutes. Maximum ESD To meet the specified value. The maximum ESD measured (while the varistor voltage is within ±30 % of its nominal value) when exposed to ESD 10 times (five times for each positive-negative polarity) based on IEC61000-4-2. Solder ability To meet the specified value. The part shall be immersed into a soldering bath under the conditions below. Solder: H63A Soldering flux : Ethanol solution of rosin (Concentration approx. 25 wt%) Soldering temp. : 230±5 °C Period : 4±1 s Soldering position : Immerse both terminal electrodes until they are completely into the soldering bath. Resistance to soldering heat ΔVc / Vc : within ±10 % After the immersion, leave the part for 24 ±2 hours under the standard condition, then evaluate its characteristics.Soldering conditions are specified below: Soldering conditions : 270 °C, 3 s / 260 °C, 10 s Soldering position : Immerse both terminal electrodes until they are completely into the soldering bath. Temperature cycling ΔVc / Vc : within ±10 % After repeating the cycles stated below for specified number of times, leave the part for 24±2 hours, then evaluate its characteristics. Cycle : 5 cycles Step Temperature Period 1 Max. Operating Temp. 30±3 min 2 Ordinary temp. 3 min max. 3 Min. Operating Temp. 30±3 min 4 Ordinary temp. 3 min max. Biased Humidity ΔVc / Vc : within ±10 % After conducting the test under the conditions specified below, leave the part 24±2 hours, then evaluate its characteristics. Temp. : 40±2 °C Humidity : 90 to 95 %RH Applied voltage : Maximum allowable voltage (Individually specified) Period : 500+24 / 0 h High temperature exposure (dry heat) ΔVc / Vc : within ±10 % After conducting the test under the conditions specified below, leave the part 24 ±2 hours, then evaluate its characteristics. Temp. : Maximum operating temperature ±3 °C (Individually specified) Applied voltage : Maximum allowable voltage (Individually specified) Period : 500+24 / 0h Nov. 2016 04 |
