Transcription

1 PTC Thermistors For Degaussing, FETURES a. Dual or double mono PTC degaussing. M6 Residual currents as low as 2 m (p-p), ideal for high-resolution displays Long decay time Stable performance over a long time (>20000 operations) Self-extinguishing white plastic case ( UL 9.V.0 ) Design-in support available. PPLICTIONS b. Mono PTC degaussing. QUICK REFERENCE DT CC2 PRMETER VLUE UNIT Resistance of degaussing PTC (R s ) at 25 C to 0 Ω Standard tolerance on resistance of 20 and 25 % degaussing PTC (R s ) at 25 C Resistance of heater PTC (R p ) at 25 C 000 Ω Colour televisions Colour monitors. DESCRIPTION For good picture definition, colour televisions and monitors must be degaussed by a strong alternating magnetic field which gradually and symmetrically decays to a small value of residual current. This can be achieved by connecting a PTC thermistor in the degaussing circuit. The new generation of flat-screen, high-definition colour televisions and monitors require an excellent picture quality with high colour purity. This can only be achieved by a dual PTC device housing two PTC thermistors in intimate thermal contact, one being used to heat the other and so further reduce the residual current. Standard tolerance on resistance of 75 % heater PTC (R p ) at 25 C Maximum C voltage (RMS value) 15 to 276 V Minimum inrush current (peak-to-peak 10 to 0 value) Temperature range (at maximum voltage) 0 to 60 C vailable pitch: e/1e to 2.5 mm e/2e to 5.08 mm Standard pin length.2 mm Detailed specifications based on CECC 000/ IEC For technical questions contact: nlr.europe@vishay.com Document Number: Revision: 10-Oct-0
