PTC Thermistors

www.DataSheet4U.com 2322 662 96... PTC Thermistors For Degaussing, Dual, Mono And Double Mono Cased FEATURES a. Dual or double mono PTC degaussing. Vishay BCcomponents • Residual currents as low as 2 mA (p-p), ideal for high-resolution displays • Long decay time • Stable performance over a long time (>20000 operations) • Self-extinguishing white plastic case (“UL 94.V.0” ) MBB633 • Design-in support available. APPLICATIONS • Colour televisions b. Mono PTC degaussing. • 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.
