Wire-Wound
Describes a type of resistor or inductor made by winding a wire, usually made of a resistive material, around a core.
Ceramic Core
A core material made from ceramics, typically used in casting processes to create intricate metal parts with high precision.
Resistive Wire
A type of wire that has significant resistance to electric current, often used in heating elements or resistors.
