MZ6 75C 800 to1200 Ohm Dia 6mm Time Delay Starting MZ31 PTC Thermistor For Lighting
Description
MZ31 series of PTC Thermistor are applicable to various types of fluorescent lamp, electronic
ballast and electronic energy-saving lamp. The PTC can be connected across the lamp resonator
without changing the circuits. It can change hard start of the ballast and electronic energy-saving
lamp to preheated start and the preheating time of the filament can come up to 0.4-2 seconds,
which will extend the service life of the fluorescent tube by over 3 times.
These directly heated ceramic-based thermistors have a positive temperature coefficient and are primarily intended for overload protection. They consist of a ceramic pellet soldered between two tinned CCS wires and coated with a UL 94 V-0 high temperature hard silicone lacquer.
Application
The application of the PTC thermistor to achieve preheated start is
as follows: Immediately after power is switched on, Rt is in normal
temperature state and its resistance is far lower than the C2
resistance. The current through C1 and Rt forms a return circuit to
preheat the filament. After about 0.4-2 seconds, Rt joule heat
temperature exceeds Curie point Tsw and skips into high resistance
state of far higher than C2 resistance. The current passes through
C1 and C2 to form a return circuit, which causes L
resonance and produces high voltage to light the fluorescent tube.
resonance and produces high voltage to light the fluorescent tube.

MOUNTING
PTC thermistors can be mounted by wave, reflow, or hand-soldering.
Current levels have been determined
according IEC 60738 conditions. Different ways of mounting or
connecting the thermistors can influence their
thermal and electrical behavior. Standard operation is in still
air, any potting or encapsulation of PTC thermistors is not
recommended and will change its operating characteristics.
