The CDH103R Series is an ultra-low-profile, SMD Shielded Power Inductor. It features a 10.0 mm × 10.2 mm footprint with an exceptionally slim 2.8mm height. This ultra-low profile makes it an outstanding solution for height-critical applications.
Despite its slim design, the CDH103R series delivers excellent high-current performance, with a saturation current (Isat) up to 11.2A. Its closed magnetic circuit design minimizes EMI, and it offers a higher current rating than conventional inductors of similar size. It is the ideal choice for power circuits in thin notebooks, flat-screen TVs, and other high-density, low-profile devices. This high current smd inductor features a robust inductor coil and includes popular values like the 10uh smd power inductor (CDH103R-100M).
Key Features
Ultra-Low Profile: 2.8mm maximum height, ideal for height-restricted designs.
