High Current Molded SMD Power Inductor 0630 1040 1265 Series
SMT Chip Inductor Unshielded SMD Power Inductor 1.0uH 2.2uH 22uH for Consumer Electronics and Smart Home
Product Overview
SMD Power Inductors are miniature magnetic components designed for high-density surface mount assembly. As the backbone of modern power management systems, these inductors are essential for energy storage, voltage conversion, and noise filtering in Switch Mode Power Supplies (SMPS) and DC-DC converters. Engineered to meet the growing demand for smaller, thinner, and more efficient electronics, our SMD series offers a wide variety of structures—including Molded (Integrated), Wire-wound, and Shielded types—to provide the perfect balance of performance and footprint.

Product Features
Ultra-Low Profile Geometry: Available in heights as low as 1.0mm, making them ideal for ultra-thin portable devices and high-density PCB layouts.
High Saturation Current (Isat): Designed with high-permeability magnetic materials (Iron Powder or Ferrite) to handle heavy peak loads without abrupt inductance drops.
Excellent Thermal Management: Utilizing low-loss materials and high-conductivity copper, these inductors ensure minimal temperature rise even during continuous high-current operation.
Standardized SMT Packaging: Supplied in industry-standard Tape and Reel (T&R) formats, compatible with high-speed automated pick-and-place equipment for efficient mass production.
Robust Construction: Features durable terminal electrodes with high solderability and resistance to thermal shock, meeting stringent industrial and automotive standards.
Q1: What is the primary technical advantage of "Molded" (Integrated) SMD inductors over traditional "Drum Core" types for high-frequency DC-DC stages?
Molded Power Inductors are constructed by pressing iron powder directly around the coil, creating an integrated, gapless structure. This offers three critical advantages: 1) Soft Saturation: Unlike traditional drum cores that saturate abruptly, molded types drop inductance gradually, providing a safer margin for peak currents. 2) Lower EMI: The entire core acts as a natural magnetic shield, drastically reducing radiated noise. 3) Compactness: They achieve higher current ratings in the same physical footprint, which is essential for high-performance VRM modules in laptops and servers.
Product Applications
Consumer Electronics: The primary power solution for smartphones, ultra-books, tablets, and high-performance graphics cards (GPU).
IoT & Wearables: Provides stable filtering and power management for compact smartwatches, fitness trackers, and wireless sensors.
Automotive Electronics: Essential for ADAS modules, infotainment systems, and LED headlamp drivers (available in AEC-Q200 grades).
Telecommunications: Used in 5G base station modules, routers, and high-speed networking hardware for stable DC-DC conversion.
Q2: Why should designers specify "Magnetic Shielded" SMD inductors for mobile or noise-sensitive PCB layouts?
In high-density layouts like smartphones or IoT modules, components are packed tightly. A Non-shielded inductor acts as a miniature antenna, radiating magnetic flux that can interfere with adjacent analog signals or high-speed data traces (causing crosstalk). Magnetic Shielded inductors use a ferrite epoxy coating or a physical magnetic sleeve to contain the flux within the component. This not only improves the overall EMC/EMI performance of the product but also prevents adjacent components from affecting the inductor's own inductance value, ensuring stable circuit operation.
Product Advantages
Extreme Space Savings: Delivers high power density in miniature footprints (ranging from 2012 to 1210 metric sizes and beyond), allowing for smaller overall device designs.
High Efficiency & Low Losses: Optimized for low DC Resistance (DCR) and low core losses, maximizing battery life and reducing energy waste in power-critical applications.
Enhanced Reliability: The solid-state design provides superior resistance to mechanical shock and vibration, ensuring a long maintenance-free service life.
Scalable Customization: We offer flexible customization for specific inductance values, current ratings, and specialized materials to meet the unique requirements of next-generation electronic designs.
