Our metal type largest size
The CVK2522H series (W25mm × D20mm × H22.5mm) is one of the largest products in our metal-type power inductor lineup, achieving an improvement of over twice the rated current compared to similar ferrite products. It offers a range of inductance values from 1.0μH to 15μH. By increasing the size and adopting a high-density winding structure with flat wire, we have reduced the DCR while optimizing the balance of allowable current for each inductance value. This has enabled us to achieve rated currents that exceed those of conventional products, making it suitable for applications requiring higher currents. In addition to various power module applications, this product is also suitable for audio-visual applications and for use in harsh temperature environments, taking advantage of its minimal variation in DC superimposition characteristics due to ambient temperature changes. - Achieves high current capability using metal magnetic materials - Adopts flat wire for low resistance and high current specifications - Minimal variation in DC superimposition characteristics due to ambient temperature - Operating temperature range of -40°C to +150°C (including self-heating) - AEC-Q200 compliant - The CVK2522H-1R0M can handle DC superimposition allowable currents exceeding 200A.
