Detailed Product Description

Circuits Automatic Degaussing MZ71-18RMB 18 OHM 60C PTC Thermistor

Description

MZ7 PTC thermistor are used as automatic degaussing components in color TVs and color displays, and current-limiting components in AC circuits.

MZ71, 72, 73 series PTC thermistors and Degaussing PTC Thermistorare mainly used in degaussing circuits of color TVs, displays and other CRTs, which can effectively eliminate image distortion, abnormal colors or irregular images caused by stray magnetic fields, and make color The picture is more vivid and clearer. It has the advantages of low residual current and good reliability. At present, the development trend of automatic degaussing PTC thermistors is small size, low resistance, low residual current, high impact resistance, and high reliability.

3-1	Resistant for Zero Rated Power	600-800Ω	Atmosphere Temperature:25±2℃ Accuracy of the Test:±0.5%
3-2	Over Voltage Withstanding	≥800V ΔR/Rn≤20% No visual damage	Starting Current:≥200mA, Starting Voltage:220VAC,hold on for 7s,and then change to high voltage800VAC,for 6s.the is shown as follows: Stay under the conditions of regular temperature and humidity for 4-5 hours, and then check the Rn again.
3-3	Over Current withstanding	≥200mA ΔR/Rn≤20% No visual damage	Starting Current:≥200mA,Voltage 220VAC, switch on the circuit for 1 minute after every 5minutes, switch-off, and repeat this operation for 20 times. Put it under the conditions of regular temperature and humidity for 4-5 hours and then check the Rn again
3-5	Curie Temperature	75℃	Check the temperature at 2 times Rn.

Other Performance

Number	Items	Technical Requirements	Test Conditions
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 rate of resistance before and after the test ΔR/Rn≤20%	Do the test according to GB2423-28 of Tb stsy under the regular temperature and humidity for 4-5 hours, and then check the Rn again.Dipping terminals to a depth of 15mm in a soldering bath of 255℃±10℃,and to the place of 6mm far from PTC boby for 3±0.5s
4-4	Intensity of terminal	Check the variation rate of resistance before and after the test ΔR/Rn≤20% No Visual Damage No break out	Do the test according to GB2423-29 of U Test Ua: Fasten the body and apply a force gradually to each lead until 10N and then keep for 10sec.hold the body and apply a force to each lead until 90° slowly at 5N in the direction of lead axis and then keey for 10sec,and do this in the opposite direction repeat for other terminal.
