Product Description
Wurth Elektronik 744373240033 is a shielded multilayer surface mount inductor housed in a compact 4020 package. Designed with a composite iron powder core and wirewound construction, this inductor offers high current capabilities with a maximum DC current rating of 8 amperes. It provides a nominal inductance of 330 nH with a tolerance of ±20%, making it suitable for precision filtering and energy storage applications in modern electronic designs.
The inductors are magnetically shielded, which effectively minimizes acoustic noise and magnetic interference, ensuring optimal performance in sensitive environments. The maximum DC resistance of only 8.6 milliohms contributes to energy efficiency by reducing resistive losses and heat generation.
With a maximum operating temperature up to 125°C and a minimum of -40°C, the device is suitable for use in automotive and industrial electronics requiring robustness. Its maximum self-resonant frequency of 143 MHz supports high-frequency switching power supplies, DC-DC converters, and FPGA power regulation circuits.
These inductors use surface mount termination technology compatible with tape & reel packaging, facilitating automated placement on PCBs. The product complies with major industry standards including RoHS, IEC 61249-2-21, JEDEC JS709B, and REACH, ensuring environmental safety and quality reliability. This component is ideal for applications such as power management, mainboards, graphic cards, and portable device power supplies.
Applications include DC-DC converters for high current power supplies, POL converters, battery-powered devices like PDAs and digital cameras, and other electronic modules requiring filtered power delivery with low electromagnetic interference.
Compact 4020 package size supports space-constrained designs. Magnetic shielding prevents acoustic noise and leakage flux. High current carrying capacity ensures durability in transient conditions. Broad temperature range supports automotive and industrial standards.
Broad frequency capability enables versatile DC-DC converter applications. Explore a wide range of Surface Mount Inductors and related electronic components on EnvMart for your industrial, laboratory, commercial, or manufacturing needs.
