Additional Details

The 4308R-101-121LF has a resistance value of 120 ohms. The '101' marking is a standard EIA code where the first two digits represent the significant figures, and the third digit represents the number of zeros. It has an isolated configuration where each resistor is electrically isolated from the others. It features a power rating (typically around 0.125W per resistor or 0.75W total package), and is designed for reflow soldering processes. The resistance tolerance is typically ±2% or ±5%, depending on the specific datasheet. The temperature coefficient of resistance (TCR) is typically ±100 ppm/°C.
