The VSRUX27 series includes L and S versions, and 12 specifications have been developed so far. The S series offers relatively higher saturation current, up to 150 A. The inductance range is 0.86 μH to 11.0 μH, the DC resistance is 0.46 mΩ to 1.92 mΩ, and the saturation current is 36.0 A to 150.0 A. It can easily handle higher peak transient currents and ensure stable operation of onboard power systems under dynamic loads.

II. Product Features
1. Optimized structure for better heat dissipation and vibration resistance
The VSRUX series uses flat wire winding technology. Compared with traditional winding, the flat coil has a larger cross-sectional area, which significantly improves heat dissipation efficiency and provides excellent thermal performance and low temperature rise. It is well suited to compact onboard electronic devices and helps ensure long-term stable operation.
The three-terminal soldering structure provides firm welding and vibration/shock resistance above 10 G, allowing the product to withstand bumps and vibrations encountered during vehicle operation.

2. Low-loss magnetic core material for high power conversion efficiency
The VSRUX27 series uses CODACA's self-developed low-loss alloy powder magnetic core material. The low core loss effectively reduces temperature rise and improves overall conversion efficiency.
A comparison test was conducted at operating temperatures from 25°C to 100°C on the VSRUX2714L-2R3LC and a similarly sized inductor from a peer brand at different frequencies. The results show that the core loss of the VSRUX2714L-2R3LC is significantly lower than that of the comparable product at each frequency, and at 200 kHz it is about 25% lower.

3.High saturation current to handle peak transient current
The VSRUX27 series has excellent DC bias capability and can withstand larger transient peak currents, ensuring stable inductor performance. The VSRUX27 L series has a saturation current range of 36.00 A to 100.00 A, while the VSRUX27 S series ranges from 50.00 A to 150.00 A.
4.Excellent temperature stability with no thermal aging issues
The inductors use alloy powder magnetic core material and offer excellent thermal stability. Saturation current tests at high and low temperatures show that the saturation current curves of the VSRUX series remain nearly identical across different temperatures, with minimal performance degradation and no thermal aging issues, ensuring high stability and reliability during system operation.
