Additional Details

The 4308R-102-390LF features a resistance value of 39 ohms. The '102' marking adheres to the EIA code, where the initial two digits indicate significant figures and the final digit represents the number of zeros. With an isolated configuration, each resistor operates independently. It has a power rating (typically around 0.125W per resistor or 0.75W for the entire package), and is designed for reflow soldering. The resistance tolerance generally falls within ±2% or ±5%, contingent upon the specific datasheet. The temperature coefficient of resistance (TCR) typically stands at ±100 ppm/°C.
