New Ferrite Material Features Low Power Loss
N95 is a new power ferrite material from EPCOS. This material features an exceptionally low power loss. In contrast to existing materials, N95 offers a constant minimum of 310 kW/m3 over a broad temperature range of between 60 and 100 degrees C. Depending on the temperature, this figure is 15 to 54 percent lower than the losses of conventional ferrite materials. Another … [Read more...]
Ferrite Chip Bead Arrays Suppress Signal Line Noise
The Type FBA denotes a multilayer ferrite chip bead array from KOA Speers Electronics that retains all the features of multilayer ferrite chip beads. It suppresses noise in signal I/O lines and other circuits that require multi-bead noise suppression. The single-package FBA conserves PCB “real estate” and helps to reduce assembly costs. The series is available in a wide range … [Read more...]
