2、 Core features and technological advantages
Breakthrough in surge resistance performance
The anti surge metal film surface mount resistor EGM16FT1R00DES adopts a nickel chromium alloy metal film layer and thickened electrode design, which increases the conductive cross-sectional area by 18% and can withstand instantaneous surge currents up to 20A/10 μ s (measured data). In power input applications, its energy absorption efficiency is increased by 35% compared to ordinary resistors, effectively protecting back-end MOSFETs or ICs from impact damage.
Precision resistance and low-temperature drift characteristics
A resistance accuracy of 1R ± 1% combined with a temperature coefficient of ± 50ppm/℃ ensures that the resistance fluctuation is less than 0.6% within the range of -55 ℃ to+125 ℃. For example, in the motor controller of an electric vehicle, the resistor serves as a three-phase current sampling element, and the current detection error caused by temperature drift can be controlled within 0.2%.
Efficient heat dissipation and power carrying capacity
The 1206 package optimizes the thickness of the internal copper layer (up to 45 μ m) and the thermal conductivity path of the ceramic substrate, resulting in a temperature rise of only 28 ℃ (measured value) at 1W power, and a 22% increase in heat dissipation efficiency compared to traditional thick film resistors. This design enables it to operate stably in high-density PCB layouts, avoiding performance degradation caused by overheating.
Vehicle grade reliability certification
Passed AEC-Q200 certification, able to withstand 3000 hours of high temperature and humidity (85 ℃/85% RH) testing and mechanical vibration (20G acceleration), suitable for harsh environments such as engine compartments and car chargers.
