Würth Elektronik has announced the WE-TMSB product family, which the company believes is the smallest chip bead ferrite in the standard 0201 chip format. This package design increases packing density of components on circuit boards three-fold compared with the chip bead ferrite packages previously available on the market.

Miniaturisation of electronic circuits not only requires small components, but also interference-free operation. These small chip bead ferrites are therefore suited for mobile devices. Their delicate layer structure enables broadband interference suppression with impedances up to 300Ω. Data, clock, audio and video signals, as well as power supply lines, can be filtered up to the gigahertz range.

Five different types are currently available for rated currents up to 300mA and operate over a temperature range from -55 to +125°C. All components are available from stock. Samples are available free of charge.

The number of product discontinuations announced on the market has increased over recent months, especially for large package sizes of chip bead ferrites that are predominantly used in industrial applications. Würth Elektronik continues to offer its chip bead ferrites in the sizes 0402, 0603, 0805, 1206, 1806, 1812, 2220 and 3312.
