Featured Products
Automotive Grade Thin Film Chip Resistor - AT Series
Yageo's automotive grade sulfur resistant, thin film, high precision, high stability chip resistor offers case sizes from 0402 to 1206, resistance range of 10 Ω-1 MΩ, narrow tolerance of ±0.1%, ±0.25%, ±0.5%, ±1% and low TCR of ±15, ±25, ±50 ppm/°C, with power rating of 1/16 W-1/4 W.
The robust AT series design is an excellent solution for automotive electronics applications where high temperature/moisture resistance and superior anti-sulfuration characteristics are required.
High Precison High Stability Thin Film Chip Resistor - RT Series
Yageo's thin film chip resistor - RT series is manufactured with advanced sputtering technology to form a nichrome (NiCr) resistive layer on the ceramic substrate. Compared to the printing process of thick film resistors, the metal resistive layer allows thin film resistors to achieve both low TCR (down to ±5ppm/ºC) and tight tolerance (down to ±0.01%). In addition, the current noise of thin film resistors is also lower than thick film resistors. As such, it is a perfect solution for application with high precision and high stability requirements.
Yageo Automotive Grade Chip Resistors - AC Series
Yageo AC Series Automotive Grade Chip Resistors feature superior resistance against the sulfur-containing atmosphere and halogen-free epoxy with MSL class I compliance. These resistors operate at 1Ω to 22MΩ resistance value range. The AC automotive-grade chip resistors also comply with AEC-Q200 standard, J-STD-020D, and RoHS compliance. These resistors are ideal for car electronics, industrial, and general-purpose applications.
Yageo Automotive Grade Surge Resistor - SR Series
Yageo SR Series Anti-Surge Chip Resistors feature superior pulse withstanding voltage, reduce environmentally hazardous waste, and comply with MSL class I. The resistance value of the SR Series Anti Surge Chip Resistors ranges from 1Ω ≤ R ≤ 1MΩ. Yageo SR Series Anti-Surge Chip Resistors offer high component and equipment reliability, and comply with RoHS compliance. Yageo SR Series Anti-Surge Chip Resistors are ideal for telecommunications and power supplies.
