Product Description
Surface Mount Low Profile NTC Negative Temperature Coefficient Thermistor 44mm 45mm
Description Of The NTC Negative Temperature Coefficient Thermistor
Ampfort has released a new Thin Film NTC Thermistor. The Thin Film NTC Thermistor are frequently used for applications where space is a concern and standard design are not thin enough. With a typical thickness of 0.9mm max offers the solution engineers have been looking for. They are an ideal choice for precise temperature measurement between flat surfaces where quick time response is critical. The thermistor chip is loaded between 2 conductors then sandwiched with polyimide insulation. This provides excellent moisture resistance, along with flexibility. All the usual benefits of thermistors where sensitivity to temperature change is paramount.
Features Of The NTC Negative Temperature Coefficient Thermistor
• Insulated membrane packaged,with fast thermal induction and high sensitivity.
• Good stability and high reliability.
• Good insulating property.
• High resistance precision.
• Safe in use.
• Small in volume,light in weight and firm in structure, applicable to automatic installation.
Purpose Of The NTC Negative Temperature Coefficient Thermistor
• Temperature measurement.
• Temperature control.
• Temperature compensation.

Precautions Of The NTC Negative Temperature Coefficient Thermistor
• Do not bend the resistance coil holder lest the resistance deviates due to the shake-off of chips and coil holder.
• keep the temperature under 300℃ at soldering and not more than 0.5 seconds for soldering.
• Use hot air gun for heat shrinking tubing and keep the air gun at about 120℃ in temperature.
• When soldering, use constant temperature iron, with one hand holding the resistor, the other holding electric wires for butt-welding to improve the productivity and shorten the soldering time.
• Special notice: never touch the chip (the top of resistor) with hand.
