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.

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.
