DESCRIPTION
The conventional fluorescent strip lamp is rapidly being superseded by a more compact fluorescent lamp in which the old troublesome starter is replaced by an electronic ballast circuit which pre-heats the cathode to make ignition easy. Positive Temperature Coefficient (PTC) thermistors for overload protection have proved to be the ideal electronic ballast component for companies worldwide. When the rectified mains is first applied, the PTC thermistor is cold, so its resistance is low. The lamp voltage will be below the necessary ignition value, so the current will flow through the cathodes, heating them to their emission temperature. At the same time, the PTC thermistor will heat up to its switch temperature, whereupon its resistance will rise rapidly, allowing the lamp voltage to reach its ignition value and light the lamp. Once the lamp is lit, the cathodes are fed by a high-frequency (36 kHz) lamp supply, to avoid flicker, via two power FET switches. The PTC thermistor plays no further part until the lamp is switched off, whereupon it is ready to resume its smooth-starting function. We supply a range of overload PTC thermistors for this application offering a wide choice of voltage and switch temperatures.
MOUNTING
The leads are suitable for soldering in any position. The lacquer may cover the leads up to 1.0 mm from the seating plane.
PACKAGING
All tape and reel specifications are in accordance with "IEC 60 286-3".
