Stackpole Introduces Ferrite Bead Chip Inductors
RALEIGH, NC (September 21, 2005) - Stackpole Electronics, Inc. has introduced a broad offering of multi-layer ferrite bead chip inductors for general use, high-current and high-speed signal applications.
Designated the CB Series, these ferrite bead chip inductors have impedance ranges from 6 to 2700 Ohms (at tolerances of ±20% and ±25%), with rated currents of 50mA to 6A - and DC resistances of 0.02 to 1.2 Ohms.
The CB Series of inductors is offered in 0402 to 1812 case sizes and are supplied on 1K to 10K piece reels for high volume pick and place manufacturing environments. The nickel barrier terminations provide excellent solder heat resistance even when using high temperature, lead free solder processes.
The CB Series of chip ferrite beads function as a resistor or attenuator at high frequencies. Lower frequencies that are desired are allowed to pass where higher frequencies are blocked and the energy released as heat.
These devices are frequently used for EMI and RF suppression, power supply filtering, and isolation for logic devices. Typically, the beads are effective in applications across a wide frequency range from 1MHz to several hundred MHz.
Typical applications include graphics cards, field programmable logic, voltage regulation modules, point of load converters, and DC to DC converters in laptop, notebook, and tablet PC's.
The CB Series is RoHS compliant with lead-free 100% matte tin terminations and is available in the values listed in the following grid:
Typical pricing for the CB Series is US$ 0.05 each, in volume quantities. Lead times are from stock to 6 weeks.
