The KRC106S-RTK/P is a NPN pre-biased 100mA 50V SOT-23-3 (or SOT-23) RoHS transistor manufactured by the Korean company KEC. It is a three-terminal, through-hole package and features a wide range of maximum collector-emitter voltage, collector current, and power dissipation. It can be used in a range of applications such as switching, amplifying, and logic gates. Its main characteristics include a wide operating temperature range of -40°C to 125°C, fast switching speeds, low noise, and a low saturation voltage. The KRC106S-RTK/P is an ideal choice for applications in portable electronic devices, automotive electronics, telecommunications, industrial applications, and home electronics.
