  • Use high surface area flat-wire for windings and offer inductance values ranging from 10 μH-22 μH

Original Press Release:

Magnetically Shielded Power Inductors Perform in Class D Digital Amplifiers

Sumida’s magnetically shielded DEP1519B Series Power Inductors are designed for applications in class D digital audio amplifiers, as well as in DC to DC converters and other low-pass filter applications. To minimize internal resistance at high frequencies, high surface area flat-wire is used for the windings. The flat wires also allow more compact construction with higher current ratings. Device size is further reduced by self-shielded metal-hybrid construction.

Inductance values range from 10 μH – 22μH in four options. DCR is just 9.2mW (typ.@ 20°C) for all values. Saturation current for the 10.0µH value is 26 amps, typical. Maximum size for all values is just: 18.0×15.5×19.3mm (L×W×H ). The DEP1519B Series offers a full-rated temperature range of -40° to +125°C.

Applications include class D audio amplifiers, such as those used in automotive infotainment systems, portable audio equipment, home theater receivers and subwoofer circuitry. DC-DC converters, and other designs requiring high current and small size are also a good match for the DEP1519B.

The device is RoHS compliant and halogen-free. Solder reflow temperature to 260 °C peak. Complies with IPC/JEDEC Moisture Sensitivity Level 1, for unlimited floor life at ≤30 °C/85% RH.

Like other Sumida products, DEP1519B Series power inductors meet or exceed the highest industry standards for quality and repeatability. Full application engineering support is available.

The DEP1519B Series power inductors are in stock for immediate delivery. For more information visit: Direct link to data sheet: Landing page:
