VISHAY FOIL RESISTORS  Y20195R00000E9W  片式电阻器, 表面贴装, 金属箔, LED1625系列, 5 ohm, 300 V, 2516 宽 [6440 公制], 1 W, ± 0.2%

The LED1625 series ultra high precision LED Bulk Metal® Foil Resistor offers modern LED-backed LCD, screen brightness is a very important function. The brightness is obtained by the LED panel-mount to the rear of the LCD, which controls brightness by boosting the input voltage connected to the panel. A boost converter converts the Li-ion battery voltage to dozens of volts for the LED panel operation. To avoid brightness flickering and to control the stability of the LED output voltage, stable and precise current sense resistors with low thermal EMF and low absolute temperature coefficient of resistance are used.
