Color cathode-ray tube
A rectangular-shaped deflection yoke, RTC (Round Core Tetra Coil Combined Deflection Yoke) enhances deflection sensitivity of a cathode-ray tube. More specifically, a deflection yoke structure for a cathode-ray tube is mounted with rectangular shaped deflection coils and circular shaped ferrite cores, and the difference between a maximum gap and a minimum gap for the deflection coil and the ferrite core is greatest at an end section on a screen side of the ferrite core.
