SW Series

AIKOH ELECTRONICS Co., Ltd. Headquarters、Osaka Branch (Remote Work)
  • Official site

We use high-performance and reliable products from Japanese manufacturers for not only electrolytic capacitors but also most other major electronic components.

The characteristic of Japanese electronic components is their high reliability, which is achieved through the meticulous design and manufacturing processes unique to Japanese manufacturers. As a result of adopting these components and designing them domestically, the AC adapters themselves can maintain stable quality for a long time compared to overseas-made adapters. (We have successfully kept product costs down by conducting assembly overseas.) Our website → Products → AC Adapters → High-Quality Switching AC Adapters * As of April 1, 2020, we received notice from the manufacturer that production has ended, and sales will conclude once our stock is depleted. * On May 16, 2022, the "SW-1212S" stock was exhausted. * On July 1, 2024, the "SW-0522E" stock was exhausted.

basic information

The high-quality AC adapter SW series is slightly larger compared to compact AC adapters, measuring 63.5mm in height, 48.6mm in width, and 31mm in depth. This is a result of ensuring adequate spacing between electronic components and selecting rated electronic parts with sufficient capacity. Compared to compact AC adapters, which tend to trap heat, this design is less susceptible to damage from heat, thus offering an advantage in product lifespan. *As of April 1, 2020, we received notice from the manufacturer that production has ended, and it will be available only while supplies last. *On May 16, 2022, the "SW-1212S" stock was depleted. *On July 1, 2024, the "SW-0522E" stock will be depleted.
