Method for narrow-tolerance inductance trimming of an electrical component which is provided with connecting pins or has no connecting pins, can be surface mounted, is inductive and has no trimming elements

摘要

A method for narrow tolerance inductance trimming of an electrical component which is provided with terminating pins (4) or has no connecting pins, can be surface mounted, is inductive and has no trimming elements, specifically a coil, inductor or a transformer, having a core (1) composed of magnetic material, especially ferrite or carbonyl iron, and having at least one winding (3) which is fitted indirectly onto the core (1) or onto a coil former (2) which is pushed onto the core, the inductive electrical component being trimmed to a specific inductance value by subsequent removal (7) of core material. <IMAGE>
