MZ7 PTC Thermistor

Product Summary
　　BaTiO Oxide semiconductors Current-Time characteristic applied to current control element used in degaussing circuit. Owing to its degaussing function MZ7 PTC thermistor has been widely used on color CRT’s degaussing circuit in color TV sets and color monitors. Deriving from effects of earth magnetic system, Effective omission of CRT’s shadow mask improves color hindrance。

General Function

1.Quick back from break to normal resistance value result in the capability of re-field discharge;

2. The characteristics of PTC thermistors can be constant cause of their anti-environmental design;
3. Phonelic resin shell with good fire-isolation ability and the non-effective of environment temperature;
4.Anti-impact current ability decreases the volume of field discharge coil;
5.There is no noise due to no contact, so that the life characteristics is excellent;
6.The large rush current can reduce the degaussing coil winding;
7.The extremely small stable current can prevent the trembling of display;
8.The remnant magnetization is extremely small in the stable due to the large current attenuation ratio;
9.Small installation place by down-lead resistance. Product Specification
