The LQH31MN100K03L is a wire wound surface mount High Frequency Inductor/Chip Coil with 1206 case. The wire wound inductor consists of a copper wire spirally wound around the ferrite core. The wire wound inductor for power circuits, coated with various resins over the copper wire wound around the ferrite core. The purpose of the coating resin is to improve the strength of the product. The merits of using a wire wound product are demonstrated when used in large current areas and high inductance areas. This inductor supports 20MHz minimum self-resonance frequency and ±10% inductance tolerance.
