Resistive Element: Metal glaze thick film on alumina substrate, laser-trimmed to 22 Ohm.\n\n2. Source Termination: The 22 Ohm value is commonly used for series source termination of high-speed digital lines (USB, CAN, SPI). Combined with the transmission line impedance (typically 50 Ohm), it matches the source to the line, reducing reflections.\n\n3. Current Limiting: At 22 Ohm, the resistor limits current while maintaining acceptable voltage drop. For LED driving at 20mA, the drop is only 0.44V.\n\n4. Power Rating: 0.1W allows up to 67mA continuous current (sqrt(0.1\/22)).","pin_description":"\n
