Guangjie Technology CSW Series Wide Electrode Low Resistance Resistors: Technical Support for High Current Applications

In the modern electronics industry, the demand for high-precision, high stability, and high-power processing components is increasing day by day. The CSW series wide electrode low resistance resistors launched by Viking Technology are high-performance products designed to address this trend. This series covers four package sizes: 0508, 0612, 1020, and 1225. The resistance strictly follows the E24/E96 standard, ranging from 10m Ω to 510m Ω, and has been optimized for different resistance ranges in terms of temperature coefficient. These features make the CSW series an ideal choice for fields such as power management, current detection, automotive electronics, and industrial control.

Technological innovation and design advantages

The core advantage of the CSW series lies in its "wide electrode" design. The electrode width of ordinary resistors is limited, which can easily lead to local overheating and reliability issues in high current applications. The CSW series significantly reduces the skin effect and heat accumulation on the current path by expanding the electrode area, thereby improving the overall heat dissipation capacity and current carrying performance. This design not only reduces the temperature rise of the resistor itself, but also enhances the welding reliability between it and the PCB board, reducing the risk of failure caused by thermal stress.

In terms of resistance range, the CSW series covers the low resistance range of 10m Ω to 510m Ω and strictly follows the E24/E96 standard for production. This means that users can flexibly choose from standardized resistance sequences, balancing design specifications and procurement convenience. For example, in applications that require precise current sampling, such as BMS (Battery Management System) or motor drive circuits, even small resistance deviations can affect system accuracy, and the CSW series ensures consistency through standard resistance values and high-precision manufacturing.

The temperature coefficient (TCR) is a key indicator for measuring the stability of resistance. The CSW series has designed differentiated TCR performance for different resistance ranges: for the extremely low resistance range of 10m Ω to 27m Ω, the temperature coefficient is controlled within ± 600ppm/℃; For the resistance range of 30m Ω to 510m Ω, it is further optimized to ± 200ppm/℃. This hierarchical design reflects a deep adaptation to application scenarios. Extremely low resistance resistors are usually used in high current scenarios, and their sensitivity to temperature changes is relatively low, but they still need to ensure a certain level of stability; The slightly higher resistance range may be used for more precise circuits, therefore requiring stricter TCR specifications.

Application scenarios and performance

The four volume sizes of CSW series (0508, 0612, 1020, 1225) provide users with rich layout flexibility. Smaller sizes such as 0508 are suitable for portable devices with limited space, while larger sizes such as 1225 can handle higher power and meet the stringent requirements of industrial equipment. For example, in the charging management module of electric vehicles, 1020 and 1225 packaged resistors can be used for detecting and adjusting high current paths. Their low resistance and low TCR characteristics ensure measurement accuracy and long-term stability.

In addition, the CSW series performs equally well under high frequency and pulse conditions. The wide electrode design reduces parasitic inductance and equivalent series resistance (ESR), enabling it to reduce signal distortion and energy loss in switching power supplies and inverter circuits. This is crucial for modern high-performance power supply design, especially in scenarios that require high reliability such as server power supplies and communication base stations.
