Choosing inductors for energy efficient power applications
Energy efficiency in power supplies can be as much about the inductors as about the circuit topology. A few simple calculations can prevent unpleasant surprises. CHRIS HARE, LEONARD CRANE COILCRAFT, INC. In high frequency dc-dc converters, inductors filter out the ac ripple current superimposed on the dc output. Whether the converter steps the voltage down […]
Common-Mode Choke Finder web tool locates filter components quickly
Coilcraft has launched an all-new Common Mode Choke Finder web tool that allows users to search and compare hundreds of common mode filter options in just seconds. Common Mode Choke FinderSearch results are presented in a clear table sorted by the highest impedance or attenuation, depending on the user’s input. The tool includes the ability […]
Compact Current Sense transformers sense up to 20 A
Coilcraft announces its new CST7030 Series of surface mount current sense transformers which measure just 5.2 X 7.0 mm (with a max height of 3.0 mm) and sense up to 20 Amps of current at frequencies between 10 kHz and 1 MHz. Typical applications include load current measurement and control in switching power supplies and […]
Chip inductors give low dc resistance in choke applications
Developed for use in mobile devices and cellular infrastructure equipment, Coilcraft™s new 0402DF Series chip inductors offer higher inductance values and significantly lower DC resistance than other 0402-sized inductors, making them ideal for RF choke and filtering applications. SeriesThe 0402DF Series is offered in 25 inductance values ranging from 20 to 3300 nH, with a […]
Shielded power inductors handle high saturation currents
Coilcraft’s XAL15xx Family of rugged, magnetically-shielded power inductors are offered in two versions – one providing saturation current ratings up to 111 Amps and the other offering inductance values as high as 33 µH – delivering the highest levels of performance in the smallest possible space. XAL15xxThe XAL1510 Series offers a unique combination of high […]
