Product Description

In the relentless pursuit of higher power density and efficiency, your next-generation designs demand components that deliver uncompromising performance. Our LPA2110 and LPA2112 series of shielded power inductors are engineered to meet this challenge head-on. Utilizing advanced Flat Wire Inductor technology and a robust magnetically shielded construction, these components offer exceptionally low DC resistance (DCR) and high saturation current (Isat) in a compact surface-mount package. Whether you're pushing the limits of a DC-DC converter, designing a sensitive Sensor interface, or optimizing an EMI Filter network, our LPA series provides the reliability and efficiency your products deserve. Discover how our innovative design translates to cooler operation and higher reliability in your application.

Key Features and Technical Specifications

The LPA series is built for stability and high performance under strenuous conditions, making it a superior choice for modern power management solutions.

Electrical Characteristics (Summary):

Inductance Range: 1.0µH to 50.0µH (±20% @ 100kHz)
Extremely Low DCR: From as low as 1.4mΩ (LPA2110-1ROM/RSM) to 32.6mΩ (LPA2112-500M)
High Temperature Rise Current (Irms): Up to 40A (LPA2110-1ROM/RSM), ensuring minimal heat generation under load.
High Saturation Current (Isat): Up to 70A (LPA2110-1ROM), providing robust resistance to current spikes without core saturation.
Operating Temperature Range: -40°C to +125°C, suitable for industrial and automotive environments.
Shielded Construction: Effectively contains magnetic flux, minimizing electromagnetic interference (EMI) to surrounding circuits like RF inductors or sensitive sensor modules.

Structural Advantages:

Flat Wire Technology: Enables a compact form factor while providing a larger conductor cross-section, which is the primary contributor to the very low DCR and high current handling capability.
Magnetically Shielded: Protects neighboring components from magnetic interference and reduces audible noise, making it ideal for noise-sensitive applications including audio filtering.
Robust SMD Package: Designed for reliable automated assembly and strong PCB attachment.

Designer's Note: The combination of flat wire and shielded core isn't just about specs. It directly translates to higher system efficiency and reduced thermal management challenges in your end product.

Target Applications

The LPA series' combination of high current, low loss, and low noise makes it exceptionally versatile:

High-Efficiency DC-DC Converters: Especially buck, boost, and POL (Point-of-Load) converters in computing, telecom, and network infrastructure.
Power Supplies for Industrial Equipment: Provides stable performance in motor drives, control systems, and automation.
Advanced Driver Assistance Systems (ADAS) & Automotive Electronics: Its robust build and temperature range suit various automotive power applications.
Consumer Electronics: High-current power delivery in gaming consoles, high-end displays, and servers.
Filtering Applications: Effective noise suppression in power rails and audio circuits.

Why Choose Our LPA Series Inductors?

Proven Performance in Demanding Environments: Engineered for reliability where it matters most, from industrial controllers to continuous-operation server racks.
Thermal Efficiency: Low DCR minimizes I²R power loss, leading to cooler operation and enhanced long-term system reliability.
Design Flexibility: A wide range of inductance and current ratings (e.g., LPA2110-4R7M: 4.7µH, 26A Irms; LPA2112-100M: 10.5µH, 17.5A Irms) allows precise selection to optimize your circuit's performance.
Drop-in Compatibility: Designed to be a reliable and often performance-enhanced alternative to other industry-standard parts (e.g., Bourns SRP-CC series).
