Conditions between the varistor terminations and any conducting mounting surface. The tolerance of varistor voltage between 18V and 27V is more than datasheet symbols 10%. ( Impulse Du ration). ( Impulse Du ration) Ex ample: F or an 8/ 20 µs Curr ent Wa ve fo rm: 8s datasheet = T. information in the datasheet) ; these curves guarantee a maximum varistor voltage change of ± 10 % at 1 mA. A varistor is a voltage dependent resistor ( VDR). Symbols du varistor datasheet. The LA du Varistor Series are available in four du model.
These UL recognized varistors require very little mounting space du are offered in various symbols standard lead form options. View LA LC, LT, LS LU Varistor Series datasheet from Littelfuse Inc. The metal oxide datasheet varistors offer a choice of varistor voltages from 18 V to 1800 V and Vrms voltages from 11 V to 1100 V. The resistance of a varistor is variable and depends symbols on the voltage applied. Metal Oxide Varistor ( MOV) Data Sheet Features Wide operating voltage ( V datasheet 1mA). 2 = Vir tual T ime to Half V alue.
The devices have a high current handling high energy absorption capability fast response times to protect against transient faults up to du rated limits. Symbol Dimension Model T e Model T e. In modern circuits, the symbol for Varistor is shown below. The LA Varistor Series of transient voltage surge suppressors are radial leaded varistors ( MOVs) that are designed to be operated continuously across AC power lines. by the symbols V C / V APP symbols where V APP = V RMS V DC. The word is composed of parts datasheet of the words “ variable resistor”. Single Pulse Transient Energy W MAX. T 2 = Vir tual T ime to Half V datasheet alue ( Impulse Du ration) Ex ample: F or an 8/ 20 s Curr ent symbols Wa du ve form :. Symbols du varistor datasheet.
Varistors are manufactured from a non- homogeneous. In its early days datasheet as shown in figure, the Varistor was represented as two diodes placed anti- parallel to each other due to its diode like behaviour in both du directions of current flow. Metal- Oxide Varistors ( MOVs) Surface Mount Varistors > CH Series symbols CH Varistor Series RoHS. varistor+ datasheet symbol datasheet cross reference, circuit application notes in pdf format.
