TDK Corporation presents new EPCOS leaded RF chokes with high current capability. The series with designation LBC+ offers components for rated currents of up to 4450 mA at saturation currents of up to 7700 mA. This corresponds to an increase of up to 80 percent compared to previous versions. The range of inductance values of the E12 series extends from 1.0 µH to 470 µH. These RoHS-compatible inductors are suitable for an operating temperature range of -55 °C to +125 °C.
The components of the LBC+ series are manufactured in both axial (B82144F2*) and radial types (B82144B2*). The latter have a lead spacing of 5 mm. The chokes have a length of 9.2 mm and a diameter of 6.5 mm.
A flame-retardant enamel coating protects the components against environmental effects. Moreover, they are marked for identification with color rings to IEC 60062.
Thanks to their higher current capability, the new chokes can be used for diverse functions such as storage chokes for DC-DC converters as well as for noise suppression. Their possible applications include power supplies for industrial and telecommunications installations, LED and energy-saving lamps as well as consumer electronics devices.
