356 series

      The 356 series is a kind of special type.It has five features as follows.The first one is that it is designed for high voltage applications.The second one is that it has high breaking capacity. The third one is that it is agency approved.The fourth one is that the surge is tolerant.The last one is that it is pluggable into clips or shocksafe holders.
      Then is about some the specifications of 356 series.It is packaged in 100pcs.The tube is made of ceramic and the end caps are made of nickel-plated brass.The operating temperature ranges from -25oC to +70oC (consider de-rating). The following is about the stock conditions.The temporature is from +10 to +60.The relative humidity is lower than 75% yearly average without dew and the maximum value for 30 days is 95%.Next is about the vibration resistance which is 24 cycles at 15 min. each (EN 60068-2-6) ,10 - 60Hz at 0.75mm amplitude and 60 - 2000Hz at 10g acceleration.
