Product Description
Screw Clamp PTC Overheating Sensing Protection Lug Terminal Type 120C 470 Ohm, Murata Code PTFM04BB471Q2N34BS POSISTOR Cross.Electrical SpecificationsMax. operating voltage (TA = 0-40 C) Vmax: 30 VDCMeasuring voltage (TA = 25C Tsense) Vmeas: 2.5 VDC max.Rated resistance R25: 100 Ohm max.Sensing temperature Tsense: 120C centigrade.Resistance at 105ºC (Tsense-15C): 330 Ohm max.Resistance at Sensing temperature 120C (Tsense): 470 Ohm min.Maximum permissible current: 100mAOperating temperature range Top -25-+130 COperating temperature range (V = Vmax) Top 0-+40 CScrew Clamp PTC Metal Lug Tag Terminal Probe FeaturesScrew clamp type temperature sensor, for sensing the temperature of transistors, thyristors, stereo main amplifiers, and other devices having risk of overheat.Limit temperature sensor with epoxy resin coating.Tinned pin leads wire.Metal lug tag screw clamp type easy mounting.Metal tag lug permits good thermal coupling andthus short response time.PTC thermistors with their very steep curves are very suitable for the monitoring of temperature limits and consequently for switching on a fan when a particular temperature is reached.Making use of the characteristics that the resistance of ceramic PTC thermistors increases sharply above curie temperature, when ambient temperature increases abnormally, protective circuit installed PTC thermistor will turn on or cut off loop through resistance changing, achieving thermal protection purpose.PTC thermistors protect such equipment and components as motors, transformers, power transistors and thyristors against over-temperature.A PTC thermistor is less expensive than a thermostat, and its switch temperature can be more accurately specified. It is also smaller and easier to design-in to electronic circuitry. Therefore PTC thermistors can be ideal devices for temperature detection, monitoring, indicating, limiting and over (excessive) temperature protection.
