Product Description
Bourns SRU1038 shielded wirewound surface mount inductor features a ferrite core providing 33μH inductance with a tolerance of ±30%. The inductor supports a maximum DC current of 1.8A and exhibits a quality factor (Q) of 22 at its rated frequency, making it well-suited for power management and signal conditioning circuits.
Constructed with a wirewound technique and magnetic shielding, this inductor minimizes electromagnetic interference, enhancing circuit stability. It is housed in a compact 1038 package with dimensions of 10mm length, 3.8mm height, and a 10mm depth, designed for surface mount technology (SMT) assembly on printed circuit boards.
Operating temperature limits range from -40°C to 125°C, enabling reliable performance under varying environmental conditions. The inductor's maximum DC resistance is 86mΩ, ensuring efficient current flow with minimal losses. Additionally, the part complies with RoHS directives, making it suitable for environmentally conscious electronics manufacturing.
This inductor is typically employed in the input and output filters of DC/DC converters and power supplies, contributing to noise suppression and energy storage. Its high self-resonant frequency of 10MHz supports applications in medium frequency ranges while maintaining stability.
Magnetically shielded wire wound choke reduces electromagnetic interference and signal noise. ±30% inductance tolerance ensures consistent electrical characteristics. Ferrite core material delivers high magnetic permeability and low losses.
Surface mount termination style compatible with automated PCB assembly. Operating temperature range from -40°C to 125°C for versatile use cases. Low DC resistance of 86mΩ reduces power dissipation during operation. Minimum quality factor of 22 guarantees effective performance at resonance.
RoHS compliant and lead-free for safe and environmentally friendly use. Compact 1038 package size fits space-constrained designs. Optimal for noise suppression in power supply circuits and DC/DC converters.
Choose the Bourns SRU1038 series for high-quality inductors suitable for industrial, laboratory, telecommunications, and power electronics applications. Explore more Surface Mount Inductors and related components in the Electronics & Electricals category at EnvMart.
