Brief Introduction:
PTC thermistor for time delay of lighting&ballast,which are applicable to various types of fluorescent lamp,electronic ballast,electronic energy-saving lamp and digital multi-meters.it can change hard stard of the ballast and electronic energy-saving lamp to pre-heated stard and preheating time of the filament can come up to 0.4-2.0 seconds,which can greatly prolong service life of the fluorescent tube by over 4 times.
Product Application:
1. Various types of fluorescent lamp
2. Electronic ballast
3. electronic energy-saving lamp
Selection Guide:
For a certain electronic ballast, energy-saving light, higher PTC thermistor resistance, smaller PTC ceramic body dimension, lower curie temperature, will lead to its lower power consumption, shorter preheating time, conversely, larger power consumption, longer preheating time.Generally speaking,we should select the PTC Thermistor with lower resistance, higher curie temperature(Tc point) and bigger ceramic body dimension relatively to delay the preheating time.
Advantages:
1. Used in the frequent-switching,typical switching life can pass over 100,000 times;
2. High reliability, good performance of safety and stability;
3. Wide operating temperature range;
-25 ~ +125 Celsius degree(when V=0V)
0~ +60 Celsius degree(when V=Vmax)
4. The withstanding voltage can reach to over 420-1000VAC;
5. The resistance will not drift in normal temperature.
6. Small dimension
7. Complete specifications
8. Stable delayed time
Many specifications for choice,and samples&orders can be custom made per customers' requirement.
