Detailed Product Description

Product Description:

MZ4A04D75C 5-8K RN700V (5000～8000 OHM)PTC Overcurrent Protection Thermistor

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

Electrical Performances

Number	Items	Technical Requirements	Test Conditions
3-1	Resistant for Zero Rated Power	5-8KΩ	Atmosphere Temperature:25±2℃ Accuracy of the Test:±0.5%
3-2	Over Voltage Withstanding	≥700V 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.

Application Circuit

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.
