Product Description
Wurth Elektronik 742790 is a comprehensive 1020 piece SMD Ferrite Kit designed for industrial and electronic applications where EMI suppression and signal integrity are critical.
This design kit features WE-CBF series SMD chip bead ferrites that can be mounted directly onto printed circuit boards. These ferrites effectively reduce electromagnetic interference while maintaining low DC resistance to support efficient current flow up to 6 A.
The kit includes small-sized ferrites such as 0402, 0603, and 0805 packages, offering maximal impedance up to 1000 Ω, perfectly suited for high frequency data signal lines like USB 2.0, IEEE 1394, and LVDS interfaces.
Applications cover a broad range including voltage supply filtering, control signal conditioning, RS232, RS422 communication lines, and DC/DC converter noise suppression. The ferrites are recommended for reflow soldering processes and operate reliably from - 55 °C to +125 °C, ensuring durability under harsh environmental conditions.
Specialized ferrite types in the kit include:. High Speed: Lower impedance at low frequency ranges for minimal attenuation of fast signals. Wide Band: High impedance across a wide frequency spectrum for comprehensive EMI filtering.
High Current: Designed to handle currents over 1 A with rated current referring to a 40K self-heating condition. This product complies with RoHS regulations and is manufactured in Taiwan to maintain quality and reliability.
The Wurth Elektronik 742790 SMD Ferrite Kit is ideal for industrial electronics, communication devices, laboratory equipment, and power supply modules where EMI control is essential.
