Thermistor is an electronic component used to calculate the temperature.This is a type of resistor whose resistance varies with change in temperature. These NTC thermistors are made up from the combination of metal oxides which passed through sintering process which gives negative electrical resistance versus temperature (R/T) relationship to it. Due to having a large negative slope a small change in temperature cause a huge change in electrical resistance. Basically, there are two types of thermistor one is NTC (Negative Temperature Coefficient) and second one is PTC (Positive Temperature Coefficient). If the thermistor is NTC type then it decreases the resistance as increase in temperature and PTC behavior is just opposite to the NTC. A thermistor is connected with any electrical circuit to measure the temperature of the body or the substance. This thermistor’s operating temperature range is -55 °C to 125 °C, the range of the temperature is depend upon the base resistance.   Applications Domestic application – Fridges, freezers, cookers and deep-fat fryers etc. Industrial, Telecommunication application - Process control, heating and ventilation, air conditioning, fire alarms, temperature protection in battery management/charging systems, Video and audio equipment, mobile phones and camcorders etc. Automotive application - Inlet air-temperature control, engine temperature control, airbag electronic systems etc. Thermistor can be used for temperature compensation, temperature measurement, temperature controlling.   Features Come with broad resistance range Thermistor cost is economical Provided with lacquer-coated thermistor disk Copper leads have coating of tin Having lead spacing of 5.0 mm Component remarked with resistance and tolerance Good stability, durability in environment Provide high accuracy in resistance and B-constant Product is not containing lead   Specifications Resistance at 25 degrees C: 10K +- 1% B-value (material constant) = 3950+- 1% Dissipation factor (loss-rate of energy of a mode of oscillation) δ th = (in air)approx.7.5mW/K Thermal cooling time constant <= (in air) 20 seconds Thermistor temperature range -55 °C to 125 °C

NTC thermistor has to be connected in series to the power source circuit to avoid the surge current at the instant when the electronic circuits are turned on. The device can effectively suppress the surge current, and its resistance and power consumption can be greatly reduced after that through the continuous effect of the current so as not to affect the normal work current. Therefore the Power NTC thermistor is the most convenient and efficient instrument to curb the surge current and protect the electronic devices from being damaged.   Applications Switching power supply UPS power supply Electric heaters Electronic energy-saving lamps Filament protection of color tubes Incandescent lamps and other lights electronic ballasts   Features Strong power and strong capability of surge current protection Characteristics Fast response to the rapidly surge Big material constant(B value),Small remain resistance High reliability Integral series, Extensive operating range Operating Temp. -55℃～+200℃   Specifications   R25℃ (Ω) Max.Steady State Current  （A） Approx.R @ Max.Cur  （Ω） Dissipation factor (δ)(mW/℃) Thermal time constant (s) NTC-5D-11 5 4 0.156 13 45 NTC-10D-11 10 3 0.275 14 46 NTC-8D-20 8 6 0.142 25 115 NTC-5D2-14 5 4 0.41 36 110   Package Include 1 x NTC

This power supply takes any input from 100V up to 220V AC, which is what comes out of your wall socket, and output 12V DC.   Applications Arduino UNO / MEGA, DC motors, LCD screens, DVD players, Hard Drives, Audio Gear, and most other digital devices use less than 1 Amperage .   Specifications Input : 110~240V AC  50/60HZ Output : DC 15V Output Current: 1A Standby power: Less than 0.1W Operating Temperature: 0°C to +55°C Cable length: 70 cm DC Plug Dimension: 5.5mm x 2.1mm DC Plug polarity: Positive (+) Inside, Negative (-) Outside.   Package Content 1 x Adapter     FAQ – How to choose In order to find the correct power supply for your device, you will need two pieces of information. These are Voltage (measured in Volts or V) and Amperage (measured in Amps or A). You can find this information off the back of the old power supply, or off the back of the device itself. If you do not find it on the device, you can check the manufacturer's website, or in the device's manual under "specifications". Voltage: All of the power supplies we sell are various from 5V to 24V DC. They take any input from 100V up to 220V AC, which is what comes out of your wall socket, and output 12V DC. So if your unit is not 12 Volt, you will need to find the correct adapter in our website. Amperage: Once you have confirmed that you need a 12 Volt power supply, you will need to find out how much power your device draws. This is called amperage. Next to the 12V in the specifications there will be another number followed by a capital "A" for Amps. You will need a power supply that can supply enough power for your device. If your device says it draws 3 Amp (3A), you need to use a power supply that can put out at least that many Amps. If your device states it needs 3A, then you can use a 3A, or 4A, or 5A unit. All will work. If the Amperage of your device is uneven, such as 3.13A or 4.16A, always round up. 3.13A rounds up to a 3.5A adapter, a 4.16A device will round up to a 4.5A or a 5A. Connector: All our power supplies have a connector that is standard for a 12V DC device. Most 12V DC devices use the standard tip. This tip is 5.5mm (outer barrel) by 2.5mm (inner barrel) and is center positive. It is a simple round barrel connector. To repeat, if you match the voltage and amperage, then you should not have to worry about the connector type accept in the rare occasion when your device has an unusual connector such as a double barrel, or a 4-pin, but these are easy to spot as the jack where the adapter plugs in will not be a simple circular barrel with a pin inside.   Suggestions DC Jack (Female) 2.1mm Connector w/ Screw Terminal Block Easy to install ABS material housing

HDMI 2.0 is an improved standard for AV connectivity and the heir apparent to HDMI 1.4 (released back in 2009). You'll need an HDMI 2.0-compatible HD TV if you're interested in watching the full range of 4K Ultra HD source material in the future. Features 4K Ultra HD at 50/60Hz - i.e. 2160p50 and 2160p60 - four times the clarity of 1080p60 Up to 32 uncompressed digital audio channels (compared to HDMI 1.4's eight) Up to 1536kHz audio sampling Simultaneous delivery of dual video streams to multiple users (on the same screen) Simultaneous delivery of multi-stream audio to multiple users (up to four) Support for 21:9 aspect ratios Dynamic synchronization of video and audio streams Additional CEC extensions for remote controls.   While HDMI 1.4 has a throughput of 10.2Gbps, it's only enough to support a 4K resolution of 3840 x 2160 pixels at 24, 25 and 30Hz or to display full 4K (4096 x 2160 pixels) at 24Hz. The 2160p24 and 2160p30 formats might be good enough for movie playback, but they fall short of the 50/60Hz required for 4K TV broadcasts and future Ultra HD gaming. HDMI 1.4 also only supports 8-bit colour at 4K. HDMI 2.0 improves upon this, offering 10 to 12-bit colour depth at Ultra HD resolutions.   Specifications Cable Length: Optional 1.5 Meters   Package Content 1 x HDMI cable
