Product Details
MZ21 04BE (300-500) ΩElectronic meter IC card holder protection thermistor
IC card holder protection application PTC thermistor
Protection principle
Figure 3-4 Figure 3-5 The IC card holder protection is mainly to prevent the abnormal use of the prepaid electronic watt-hour meter bayonet and to withstand external static electricity, lightning strikes, strong electricity, accidental short circuit and other attacks. At the same time, improve the reading and writing ability of IC card and prolong the service life of IC card and card table.

Precautions
R: Indicates the resistance of the thermistor other than pins 1-2
(such as the resistance of the thermistor between pins 3-4 5-6 7-8
9-10)
Tc: Indicates the switching temperature of the thermistor except
pins 1-2 (such as the thermistor switching temperature between pins
3-4 5-6 7-8 9-10) The above table is the commonly used
specifications of existing customers , can also be made according
to customer requirements
COMPANY OVERVIEW
Xian Xiwuer Electronic & Info. Co., Ltd. is located in Beiguan, Xi'an city cover in an area of 4000 ㎡, with employees of 2300, and about 580 technicians, amongthem, there are 135 engineers, 21 senior engineers. The company has total assets of 315 million RMB Yuan, fixed assets of 137 million RMB Yuan, which is a large enterprise mainly engaged in producing electronic components.The company has the largest production scale of Varistor,SPD( Surge Protective Device)and HV Ceramic Capacitor in China, with the following main products :
1. Varistors & SPD
2. HV Ceramic Capacitor
