Sumida

Sumida Corporation has been a lead manufacturer of coils and wire-wound electronic products, such as power inductors and RF inductors, since 1956. Sumida products are manufactured in various locations in Asia and Mexico, which has allowed Sumida to keep costs to a minimum, spread risk, and increase response times. Sumida components can be found in applications such as audio/visual equipment, CD-ROM drives, DVD/MD products, modems, networking hardware, liquid crystal display monitors, computer peripherals and air-conditioners, as well as electronic automotive products like anti-lock braking systems.

• Sumida is one of the leading manufacturers of coils and wire wound electronic products. Sumida currently has over 31000 products in its coil catalog-attesting to the diversity to which coil technology can be applied in the present day information age. All of Sumida’s products are manufactured outside of Japan in various locations in the Asian region as well as in Mexico. This has allowed Sumida to keep costs to a minimum, spread risk and increase response times.
• Sumida components can be found in audio visual equipment, CD-ROM drives, DVD/MD products, modems, networking hardware, liquid crystal display monitors, computer peripherals, air-conditioners, electronic automotive products such as Anti Lock Braking Systems, and a plethora of other electronic devices. See the product section of our site for more on our extensive range.

A power transformer is an electronic component where two (or more) coils share a common magnetic field. A transformer is used to transfer energy from one coil (called the primary) to the other coil (called the secondary).

Sumida offers a wide range of high quality transformers for a variety of different applications.

• Low profile power inductor with excellent current handling capabilities for DC-DC converters with low-noise requirements.
• Low profile and cost-effective magnetically shielded inductor are ideal to be used in DC-DC converter applications of mobile devices.
• High quality and efficiency ceramic and ferrite chip inductors are available in a variety of sizes to fit most any circuit.
• Versatility is found via core material change, size change, and number of coil turns, allowing these uses filtering, timing, energy, and impedance matching.
