Coilcraft has expanded its market-proven XEL Family of High Voltage Molded Power Inductors to include three new higher-voltage series: the XEL401xV, XEL4020V and XEL4030V. All three offer operating voltage ratings of 120 V, 50% higher than the standard versions. They also offer exceptionally low DC resistance and ultra-low AC losses for greater power converter efficiency at high frequencies (2 to 5+ MHz) and high ripple current.
XEL40xxV Family inductors measure just 4.0 x 4.0 mm with a maximum height of 3.2 mm and feature a rugged, composite construction that provides magnetic shielding and minimizes audible buzzing. The XEL401xV Series is available in six inductance values from 92 to 780 nH, with current ratings up to 24.0 Amps. The XEL4020V Series has 10 values from 0.08 to 2.2 µH and current ratings up to 33.2 Amps. The XEL4030V Series is offered in 13 values from 0.10 to 6.8 µH and current ratings up to 30.0 Amps.
All models offer soft saturation characteristics to withstand high current spikes. They are qualified to AEC-Q200 Grade 1 (−40°C to +125°C) standards and exhibit no thermal aging issues, making them ideal for automotive and other harsh-environment applications. They also feature RoHS-compliant, tin-silver-over-copper terminations and are halogen free.

High Voltage Molded Power Inductors
High-voltage molded power inductors are essential components in modern electronic systems, especially those requiring high power conversion and conditioning levels. These inductors are designed to handle high levels of electrical energy while maintaining high reliability, efficiency, and performance levels. This article will explore the key aspects of high-voltage molded power inductors, including their design considerations, applications, advantages, challenges, testing, and market trends.
Design Considerations for High Voltage Molded Power Inductors
The design of high voltage molded power inductors is a complex process that involves many factors, including core materials, wire types, magnetic shielding, capacitance, and operating frequency range. The core material used in high-voltage molded power inductors is typically ferrite or powdered iron, which offers high permeability and low losses. The wire used in the inductor must have high conductivity and low resistance to minimize losses and maximize efficiency. Magnetic shielding is also an important consideration, as it helps to reduce magnetic field leakage and minimize the impact of electromagnetic interference (EMI). Capacitance is another key factor, as it affects the resonant frequency and stability of the inductor. Finally, the operating frequency range of the inductor must be carefully considered to ensure optimal performance in the target application.
Applications of High Voltage Molded Power Inductors
High-voltage molded power inductors find wide applications in various industries, including power electronics, automotive, renewable energy systems, medical equipment, and industrial automation. In power electronics, high-voltage molded power inductors are used in power supplies, DC-DC converters, inverters, and motor drives. In the automotive industry, these inductors are used in electric vehicles, hybrid vehicles, and charging stations. In renewable energy systems, high-voltage molded power inductors are used in solar inverters, wind turbines, and energy storage systems. These inductors are used in MRI machines, CT scanners, and X-ray systems in medical equipment. In industrial automation, high-voltage molded inductors find applications in motor control, robotics, and factory automation.
Advantages of High Voltage Molded Power Inductors
High voltage molded power inductors offer several advantages over other types of inductors.

Lastly, they offer high efficiency, which improves overall system performance and reduces energy consumption.
Challenges in Designing High Voltage Molded Power Inductors
The design of high voltage molded power inductors poses several challenges that must be addressed to ensure optimal performance and reliability. One major challenge is heat dissipation, as high voltage and current levels can cause the inductor to generate significant amounts of heat. Another challenge is core saturation, which can occur when the magnetic field strength exceeds the saturation point of the core material. Magnetic field leakage is also a concern, as it can cause interference with other components in the system. Finally, the physical size of the inductor can be a challenge, especially in applications where space is limited.
Testing and Characterization of High Voltage Molded Power Inductors
High voltage molded power inductors must undergo rigorous testing and characterization to ensure they meet the required specifications and standards. Electrical testing is performed to verify the inductor’s electrical parameters, such as inductance, resistance, and capacitance. Mechanical testing is performed to evaluate the inductor’s physical properties, such as durability and reliability. Environmental testing is performed to assess the inductor’s performance under different conditions, such as temperature, humidity, and vibration.
