The TS3YJ203's resistance value is determined by its marking. In this case, 203 indicates 20 x 10^3 ohms, which equals 20000 ohms or 20 kΩ. Other key technical specifications include tolerance, power rating, and temperature coefficient of resistance (TCR). The tolerance specifies the allowed deviation from the nominal resistance value, while the power rating indicates the maximum power the resistor can dissipate without overheating. The TCR describes how the resistance changes with temperature.

The small size and surface mount design of the TS3YJ203 make it suitable for high-density circuit boards. The thick film technology provides good stability and reliability. These resistors are widely used in various electronic devices due to their ease of use and reliable performance.
