800 Ohm NTC PTC Thermistors

Product Description

 

Phenolic Resin Overcurrent Protection PTC Positive Temperature Coefficient MZ4 Thermistor PTC

 

Description 

MZ4 series PTC thermistors are used in various types of fluorescent lamps, electronic ballasts and electronic energy-saving lamps as preheating-starting components. Preheating of the electrodes lengthens the life of the lamps and the number of switching cycles significantly. Ampfort has been working at PTCR'S research, development and manufacturing for ten years. With rich experience, our company offers PTC thermistors for time delay and switching with high quality and reasonable price. Many lighting producers, including some famous international companies are our customers.

 

Features

1. PTC thermistor for time delay start of ballast & lamp could extend the service life of the fluorescent tube by more than 10-time
2. PTC thermistor applied in various types of electronic energy-saving lamp and fluorescent electronic ballasts
3. Switching current can pass over 100,000 times: the resistance will not float
4. The withstanding voltage can reach to over 800-1,000V AC
5. High reliability, good performance of safety and stability

6. Application:Energy-saving lamp, fluorescent electronic ballasts,and digital multi-meters

4-1 Appearance

No noticeable defect,

such as, bubbles and

micro holes, etc; NO

visible damage that

may reduce its performance; the symbol is clear

Visual Check
4-2 Welding

It's tinned evenly

and with smooth welds,

and the tinned area 95%

Do the test according GB2423-28 of Ta, put welding aid on the faze end and soaked it into the 230℃ tin solution with only 5mm distance to the PTC body above the solution, and maintain for 3-5s.
4-3 Heat Resistance

Check the variation
