Core Technical Advantages
Karma Material: Dual Assurance of Stability and Surge Resistance
This resistor employs advanced Karma alloy, which boasts an extremely low temperature coefficient of resistance (TCR ≤±20ppm/°C), ensuring stable resistance even in extreme temperatures and minimizing drift-related errors. Additionally, Karma material provides excellent surge resistance, capable of withstanding instantaneous pulse shocks several times higher than the rated current, effectively protecting against surges during motor startups or battery short circuits and ensuring long-term system reliability.
High-Precision and Low-Power Consumption:
The 1% precision ensures highly accurate current detection data, crucial for battery management systems (BMS) and DC-DC converters that demand stringent feedback signal accuracy. The 5mΩ ultra-low resistance significantly reduces voltage drop and power consumption, enhancing system energy efficiency and lowering heating risks.
High-Power Capability:
The 2.5W rated power provides ample margin, ensuring stable operation under high-current applications (e.g., new energy storage systems, server power modules) while preventing overheating damage and prolonging lifespan.
