Product Overview

The SRN4018-100M is a semi-shielded power inductor by Bourns, engineered for efficient power management. With a miniature low-profile design (max height 1.8mm) and 10μH inductance, it supports up to 1.3A rated current and 1.4A saturation current, combining high reliability with compactness. RoHS compliant and halogen-free, it suits DC/DC converters, laptops, consumer electronics, and more, enabling stable power conversion and EMI suppression in limited spaces.

Key Features

• mi-Shielded Construction：Minimizes electromagnetic radiation to reduce interference with adjacent components, enhancing circuit stability and EMC performance.
• Ultra-Miniature & Low-Profile：Measures just 4.55×3.6×1.5mm with a max height of 1.8mm, ideal for high-density PCBs and portable device miniaturization.
• High Current Handling：Rated for 1.3A (Irms) and 1.4A (Isat), ensuring stable inductance in high-current applications with minimal energy loss.
• Wide Temperature Range：Operates from -40°C to +125°C (including temperature rise), suitable for long-term use in harsh industrial and consumer environments.
• Eco-Compliant Design：RoHS 2011/65/EU compliant and halogen-free (Br/Cl ≤ 900ppm, total ≤ 1500ppm), supporting green electronic product development.

Technical Specifications

Typical Applications

• DC/DC Power Conversion：Ideal for switch-mode power supplies, stabilizing energy storage and transfer in buck/boost converters to improve efficiency and suppress ripple noise.
• Consumer Electronics：Suits power management modules in laptops, smartphones, and digital cameras, with a compact form factor for thin-device integration.
• Storage & Display Devices：Supports power systems in HDDs and LCD/TFT displays, maintaining stable current during high-speed data transmission and reducing EMI interference.
• Industrial Control：Wide temperature tolerance makes it suitable for industrial automation and embedded systems, ensuring reliable operation in extreme heat or cold.

Why Choose SRN4018-100M？
