KOA Speer’s ferrite product offering includes a full line of multilayer ferrite chip beads (MCB/CZB), power beads (MCP/CZP), inductors (MCL/MCI) and ceramic inductors (MHL/MHI). KOA Speer ferrite components are designed with a monolithic structure for a closed magnetic path that eliminates crosstalk and ensures high reliability through a wide temperature and humidity range. The nickel barrier and solder overcoat allows for excellent solderability and solder leach resistance. All styles are designed with superior termination bonding strength and are suitable for wave or reflow soldering. Tape and reel or bulk packaging is available. KOA ferrite components are utilized in telecommunication, computer, consumer electronic and data communication industries. Popular applications include sound cards, video cards, computer printers and keyboards, notebook computers, modems, cellular phones, LAM’s, PDA’s, VCR’s, network cards, DVD’s, digital T.V.’s, vehicle navigation systems, and radar detectors.
