Coilcraft has launched an all-new Power Inductor Finder web tool that allows users to quickly find and compare inductors based on their exact operating conditions: current, ripple, frequency and ambient temperature. Combining elements of several other popular tools on the site, the new Power Inductor Finder instantly calculates core and winding losses, computes temperature rise, and plots L vs. I curves for up to six parts on the same graph.

Linear Technology Corp. introduces the LT4321, an ideal diode bridge controller that replaces two diode bridge rectifiers with low-loss N-channel MOSFET bridges to increase the available power and reduce heat dissipation in a Power over Ethernet Powered Device (PoE PD). IEEE 802.3 PoE specifications require PDs to accept DC supply voltages of any polarity over their Ethernet inputs.
