Product Description
Bourns SDR0302 Unshielded Wirewound Surface Mount Inductor features a ferrite DR core delivering an inductance of 10μH with a tolerance of ±20%. Designed for reliable operation in a broad temperature range from -40°C to 125°C, this inductor is optimized for surface mount technology with a compact 0302 package size measuring 3mm in diameter, 2.5mm height, and 2.8mm depth.
This wirewound inductor offers a maximum DC current rating of 900mA and maximum DC resistance of 250mΩ, providing efficient performance in power supply circuits such as DC/DC converters and portable communication equipment. The construction includes a moulded ferrite DR core that helps minimize electromagnetic interference by the unshielded design, suitable for applications such as camcorders, LCD TVs, and car radios.
The inductor achieves a maximum self-resonant frequency of 34MHz and a minimum quality factor of 18, ensuring the device performs well in high frequency environments. Its surface mount termination style facilitates automated PCB assembly and production efficiency.
This component is RoHS compliant, supporting eco-friendly manufacturing standards.
Applications include industrial, electronics manufacturing, communication devices, and consumer electronics where a compact, reliable inductor is required for power conditioning and noise filtering.
The inductor is constructed with a wirewound coil on a ferrite DR core for stable inductance. Low profile of 2.5mm height suits space-constrained PCB designs. High maximum DC current and low resistance improve power efficiency and reduce losses.
Wide operating temperature range supports diverse operating environments. Moulded design protects the coil and core from mechanical and environmental damage. Surface mount termination enables compatibility with modern SMT assembly lines.
RoHS compliance ensures environmental safety. Discover a broad range of inductors and passive components on EnvMart to enhance your electronic designs with reliable and high-quality components.
