  With more than 15 years of industry experience in passive components, Hwalon Electronic Limited is one of the first companies in Chinese mainland to manufacture PTC thermistor, NTC thermistor, and varistor. Our company owns most advanced equipment, complete production technology, and skilled technical team, which made us enjoy high prestige in this trade both at home and aboard.

    In order to enhance the international image and the competitiveness of our company, as well as to accommodate to the demand of international environment protection, the products of our company have passed the pollution-free environment protection certification (SGS) in 2004. Besides, Our trade office and warehouse in Shenzhen ensure convenient service on bulk orders.

    Meeting customer’s satisfaction is our principle. Creating higher-valued products for buyers like you is our responsibility. We assure that we shall step forward hand in hand with you to make mutual benefit and development.

 

 

Features:

 

• High reliability, good performance of safety and stability, and used in the frequent-switching.

 

• The withstanding voltage can reach to over 600-1000VAC

 

• Switching current can pass over 100,000 times, the resitance will not float

 

• Applied in: energy-saving lamps, fluorescent electronic ballasts, and digital multi-meters.

 

Application:

 

 

    The application of the PTC thermistor to achieve preheated start is as follows: Immediately after power is switched on, Rptc is in normal temperature state and it's resistance is far lower than the C2 resistance. The Current through C1and Pptc forms a return circuit to preheat the filament. After about 0.4--2second, Rptc joule heat temperature exceeds Curie point Tsc and skips into high resistance state of far higher than C2 resistance. The current passes through C1 and C2 to form a return circuit, which causes L resonance and produces high voltage to light the fluorescent tube. To a certain electronic ballast, energy saving light, higher PTC thermistor resistance, smaller PTC ceramic body dimension, lower switch termperature, will lead to its lower power consumption, and shorter preheating time, conversely, large power consumption, and longer preheating time.

Dimentions:

• Straight
• Kinked
• K-lead
• Custom-made
