Core parameter analysis
Resistance and accuracy: 3.6 Ω± 1% (F level), meeting the strict error control requirements of precision current detection, voltage divider circuits, and other scenarios. For example, in the BMS system of new energy vehicles, this resistor serves as a voltage divider element in the balancing circuit, ensuring voltage balance of the lithium-ion battery pack and avoiding the risk of overcharging or overdischarging.
Power and temperature rise: Supports continuous 2W power output at a substrate temperature of 70 ℃, with a short-term overload capacity of 2.5 times the rated voltage, insulation resistance ≥ 10G Ω, and no risk of breakdown. The ceramic substrate and optimized conductive material design achieve efficient heat dissipation, with a resistance drift rate of less than 0.5% under continuous operation. The long-term stability has been verified through 1000 hours of 70 ℃ aging testing.
Temperature coefficient (TCR): ± 50ppm/℃, resistance drift less than 0.5% in a wide temperature range of -55 ℃ to 155 ℃, suitable for extreme environments such as automotive electronics and industrial power supplies. For example, in the motor drive phase current feedback circuit, this resistor can stably withstand temperature cycling shocks and reduce the risk of motor vibration.
Environmental protection and reliability: The terminal electrode adopts lead-free tin nickel coating, which complies with RoHS 2.0 and REACH environmental standards; Passed AEC-Q200 vehicle specification certification, the anti sulfurization characteristics have been verified through 85 ℃/85% RH wet heat testing, with a resistance drift rate of less than 0.5%, suitable for sulfur-containing industrial environments.
