Latest Patents

One of Kuroiwa's latest patents is for a surface-mounting choke coil. This innovative component features a resin coating material filled with magnetic powder, which occupies the space between the upper and lower flanges of a drum-type ferrite core. The resin coating material is designed to have a glass transition temperature (Tg) of about -20°C or lower, with a preference for -50°C or lower. This property allows the material to transition from a glass state to a rubber state, affecting its shear modulus as it hardens. Additionally, the thickness of the upper flange of the drum-type ferrite core is approximately 0.35 mm or less, and the ratio of the outer diameter of the upper flange to the diameter of the winding core is about 1.9 or more.
