Abstract: Based on the fundamental principles of ceramic capacitor, a new type of capacitor designated as multifiber capacitor （MFC） is proposed. It is made up of fiber capacitors （elements） connected in parallel and bonded together with a binder. Each element consists of fiber core （inner electrode）, dielectric coating and outer electrode. Theoretical analysis indicates that MFC has the optimum and greater capacitance in comparison with multilayer capacitor （MLC）, when the diameter of fiber core is carefully matched with the thickness of dielectric coating. MFC also has better resistance to dielectric breakdown.
