A test current of 1 mA DC is typically used to determine varistor voltage classification type. Varistor voltage clamping characteristics can be defined at various test levels ## **Rated Peak Single Pulse Transient Current** Maximum surge current, 8 / 20 Β΅s waveform which a varistor is rated to withstand for a single surge ## **Rated Single Pulse Transient Energy** Maximum allowable energy for a single impulse (see specified waveforms) ## **Maximum Clamping Voltage** Measured peak voltage across the device terminals when a current impulse of specified amplitude and waveform is conducted through the varistor ## **Typical Capacitance** Typical capacitance values are measured at a test frequency of 1 kHz. Capacitance values are only for reference purpose only, not object to outgoing inspection ## **Applications** ## **Surge protection in** Consumer electronics Industrial electronics Communication electronics Measuring and controlling systems Electronic home appliances Protection against surges induced by lighting striking incoming power lines Suppression of surges caused by switching inductive loads such as transformers, relays and coils Protection of rectification diodes, SCRs, power transistors, semiconductor devices, etc ## **General Characteristics** |**General Characteristics**|| |---|---| |Storage Temperature|: -55Β°C to +125Β°C| |Operating Surface Temperature|: 125Β°C| |Operating Ambient Temperature|: -55Β°C to +85Β°C (without derating)| |Maximum Voltage-Temperature Coefficient|: < -0.05% / Β°C| |Minimum Insulation Resistance|: 1,000 M| |Hi Pot (Leads To Case, 1 Minimum)|: 2,500 V dc| |Typical Response Time|: <15 Nero-seconds| |Epoxy Rating|: 94V-0| |Current / Energy Derating (>85 Β°C)|: -2.5% / Β°C| |DC Leakage Current|: 200 Β΅A maximum (at rated DC working voltage)| |Solderability|: MIL-STD-202F| **www.element14.com www.farnell.com www.newark.com** 12/05/12 V1.1 Page <2> ## Metal Oxide Disc Thermistors ## **Power Dissipation Ratings (P, in-watts)** |**Disc Size (mm)**|**11 V ac to 40 V ac**|**50 V ac to 680 V ac**| |---|---|---| |5|0.01|0.15| |7|0.02|0.25| |10|0.05|0.4| |14|0.1|0.6| |18|-|0.8| |20|0.2|1| |25|-|1.2| |32|-|1.6| |34 (Single)|-|2.1| |34 (Dual)|-|2.73| |40|-|2.1| |53|-|2.5| ## **Energy Derating Versus Temperature** ## **Peak Current Per Pulse Versus Pul Seduration** **Ambient Temperature, Β°C** | eee = =eS | ss ~ | SSS OO Se ae 0.04Seederβ€”S[f] ees see2 882 **Pulse Duration, Microseconds** **www.element14.com www.farnell.com www.newark.com** 12/05/12 V1.1 Page <3> ## Metal Oxide Disc Thermistors ## **Specifications Table** |**Maximum**
