High Impedance
Ferrite Chip Beads
surface mount ferrite chips provide compact, cost effective
EMI filtering for densely packed PCB designs. The small footprint
enables placement very close to troublesome high frequency devices.
Our proprietary SMT construction yields rugged components with
superior impedance vs. frequency characteristics.
Features:
·Small footprint ·Excellent retention under Bias ·Rugged, monolithic construction ·Superior impedance vs. frequency characteristics
·Economical ·Broad range of sizes ·Broad range of impedance values and current ratings
Application:
·Filtering of power input pins and devices using high speed clocks ·Filtering of low frequency input/output signals of shielded
enclosures ·High frequency filtering of medium speed clocks and video signals ·Preventing oscillations in high frequency amplifiers
·Data bus filtration ·Discrete component filtration in power supplies
Test Specifications:
·Maximum current ratings are determined by testing to a maximum temperature rise of 400 C with continuous operating current
·Board level components are rated up to a maximum of 75 volts
Tested with: ·HP4396A (100KHz - 1.8 GHz) or HP8753 (to 6 GHz) Network/Spectrum Analyzer ·HP43961A Impedance Test Kit
·HP16192A Test Fixture or Inter-Continental Microwave custom fixtures ·HP16200A DC Bias Adapter ·Philips PM2811 DC Power
Supply ·Ambient Temperature 23.5oC + 2o ·Bandwidth 3 kHz ·Sweep Time 423 ms ·Impedance is rated at + 25% @100MHz
