LQH Series High current surface mount power inductor
The LQH series high-current unshielded SMD power inductor uses a ferrite core and high-frequency design. It offers low DCR and high rated current, providing excellent Q factor and self-resonant frequency (SRF) in high-frequency applications. The product offers E12 series standard inductance values and multiple package size options to suit different design requirements. Excellent temperature stability ensures stable electrical performance across a wide temperature range. Operating temperature: -25°C to +85°C. Storage temperature: -55°C to +125°C. Soldering methods support both wave soldering and reflow soldering. It is widely used in modems, PDP/LCD TV converters, mobile wireless devices, cordless phones, car radios, GPS, wireless communication equipment, network systems, xDSL filters, and computer peripherals.

FAQ
Q: What core material does the LQH series use?
A: The LQH series uses a ferrite core with high magnetic permeability and low high-frequency loss. It is suitable for high-frequency switching power supplies, wireless communication, and other applications.
Q: What is the significance of the E12 series standard values?
A: The E12 series is an internationally recognised standard value series for resistors and inductors. It contains 12 standard values per decade (e.g., 1.0, 1.2, 1.5, 1.8, 2.2, 2.7, 3.3, 3.9, 4.7, 5.6, 6.8, 8.2). Using E12 series standard values facilitates procurement, inventory management, and design replacement, reducing supply chain complexity.
