The average computer system (PC, printer, monitor) contains numerous magnetic components, both passive (transformers, inductors, sensors) and active (cooling fan and drive motors). The number increases as more peripherals are added, such as a second CD-ROM drive, DVD drive, a scanner or laserjet printer. Arnold is prepared to supply the full range of magnetic products into this marketplace. Contact us to find out how we can assist you.
