The LED221 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.

• Input voltage usually comes from Li-ion battery

• Resistance tolerance to ±0.01%
• ±0.005% (50ppm) Load life stability
• Electrostatic discharge (ESD) at least to 25kV
• 1ns Effectively no ringing rise time
• <lt/>0.08μH Non-inductive
• High Power Resistor
