Overview of TDK Ferrite Bead Filters for Signal Line ZBF Series

The TDK ZBF Series Ferrite Bead Filters datasheet provides detailed information on a range of ferrite beads designed for noise suppression in various electronic equipment. These components offer high impedance across 30 to 1000MHz to absorb noise by resistance at high frequencies due to their low distributed capacitance. With radial lead-type designs, these ferrite beads can be mounted on printed circuit boards (PCBs) using automatic equipment insertion, optimizing the manufacturing process.

Applications

The ferrite beads are suitable for a wide range of applications, including home electronics like TVs and PCs with microcomputers, office automation equipment such as computers and fax machines, factory automation tools like industrial measuring devices, and radio equipment, including car phones and transceivers. They help control electromagnetic radiation, suppress abnormal oscillations, and prevent abnormal operation, and are effective in meeting EMI regulations, such as FCC Part 15 for the USA, VCCI for Japan, and FTZ for Germany.

Shapes and Dimensions

The datasheet lists specific part numbers such as ZBF503S-03(TA)-K-01, ZBFS503D-OO(TA)-01, and ZBF503M-OO(TA)-K-01 with corresponding weights and dimensions. These part numbers end with a “-01” designation, indicating they are Lead-free compatible products in accordance with RoHS Directive 2002/95/EC.

Electrical Characteristics

Key electrical attributes are outlined, including the rated current (maximum) and impedance versus frequency measurements for each part number, which demonstrate their ability to sustain robust performance across a range of frequencies. For instance, the ZBF503S-03(TA)-K-01 indicates an impedance of 300 min at 10 to 300MHz up to 1000 min at 30 to 70MHz.

Packaging Style and Quantities

Information on packaging style and quantities is also given, such as the minimum order of 4 boxes for different part numbers with each box containing varying pieces, such as 2500 pieces/box for ZBF503S-03(TA)-K-01 or 150 pieces/box for ZBF503M-OO(TA)-K-01.

Typical Electrical Characteristics

The datasheet includes graphs of impedance versus frequency characteristics for several product types, demonstrating the typical EMC suppression effects, and provides a measuring circuit example with an oscilloscope and vector impedance meter.

Finally, the datasheet underscores that all specifications are subject to change without notice, signaling the dynamic nature of product specifications.
