Spanish reference on SMD coils or inductors, a 273 KB PDF covering surface-mount types found on modern boards. The name gives no device. Expect notes on package shapes, markings and their role in switching regulators, filters and backlight circuits. When diagnosing a dead rail, an inductor can be tested for continuity and its output side measured for a short to ground. For replacement, match inductance, saturation current and footprint, since an undersized part may overheat or let the regulator fail under load.
