CODACA Electronic, a global leader in high current power inductor and molding power chokes manufacturing, has announced the launch of its latest innovation VPAB3822 series molding power chokes. These advanced power chokes have an impressive saturation current of up to 335A while maintaining a compact package size of just 38.25 x 38.25 x 22.0 mm. This significant leap in power density positions the VPAB3822 series suitable for high-current applications, particularly in the automotive industry.

VPAB3822 series represents a breakthrough in molding power choke design, achieving low loss and high efficiency through alloy powder and flat wire molding. This construction results in ultra-low DCR and reduced AC losses. These features ensure that the VPAB3822 can handle high transient currents while maintaining stable saturation characteristics, making it a robust choice for demanding applications. The series is designed with a through-hole structure that enhances welding stability and provides excellent anti-vibration properties. These attributes contribute to the reliability and longevity of the components, especially in environments subject to significant mechanical stress.

One of the standout features of the VPAB3822 series is its qualification for AEC-Q200 Grade 0, which certifies its operation within a wide temperature range of -55°C to +165°C. This makes the VPAB3822 series not only suitable for automotive applications but also for other high-temperature environments. The soft saturation characteristics of the molding power choke remain stable across temperature variations.

In addition to its mechanical and thermal advantages, the VPAB3822 series is equipped with magnetic shielding to minimize Electromagnetic Interference (EMI) at high switching frequencies. This feature is crucial for maintaining signal integrity in electronic systems, particularly in automotive and other sensitive applications where EMI can pose significant challenges.

The introduction of the VPAB3822 series reflects CODACA’s commitment to meeting the evolving needs of the automotive industry. With the rise of electric and hybrid vehicles, the demand for components that can handle high currents and operate efficiently in compact spaces is more critical than ever. The VPAB3822 series addresses these needs by providing a power choke that combines high current capacity, low loss, and robust performance in a compact form factor.
