Product 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.
Specification
Product Name: MZ4 PTC Thermistor
R25 : 600-800Ω±25%
Diameter : 4mm
Non-action current : 75-120℃
Max voltage : 300V-800V
Application : Electronic ballasts, energy-saving lamps
Color : Green or Yellow
Features
Silent Operation: Compared to traditional electromagnetic relays, PTCs operate without arcing or noise.
Anti-vibration: The lack of mechanical contacts eliminates reliability issues caused by contact vibration.
High Reliability: Suitable for harsh environments (such as vibration and oily environments) and boasts a long service life.
Low Cost: Simple structure, offering an extremely high cost-effectiveness.
Application
Single-phase motor starting: such as washing machine motors, water pump motors, and fan motors.
CFL and LED driver power supplies: Acts as a surge suppressor, limiting the inrush current to the filter capacitor at startup, protecting the rectifier bridge and fuse.
Transformer demagnetization: The principle is similar to that of a demagnetization circuit, providing a decaying current.
