High-Current Power Inductor for Switching Power Supplies: Benefits and Applications

In a switching power supply (SPS), the power inductor -- a key component in those SPSs--is designed. So a good inductor is required to manage storage and transfer of energy in power electronic systems and avoid wasted watts. It is hardware committed to thwarting current variations from damaging integrated circuits and initials as well as maintaining a steady current flow--all key to the continued proper function of switching power supplies. The use of shielded construction, low loss current materials and special thermal design result in these inductors having features such as high saturation currents, small resistance values (about one half that of conventional units) and exceptional long-term stability under temperatures higher than 50°C (122°F). They may so handle substantial power flows without generating excessive heat that power failure becomes unlikely. Manufactured in a range of sizes and styles, these power inductors are used in a variety industries ranging from consumer electronics to automotive applications and solar power generators. They work reliably on most any type of system that needs the ability for current flow, even if you can't see them doing their job with keys up to their usually courthouse Hermetic seals.
