Through hole resistors are one of the most versatile components available in electronic industry. RSF2GB3K30 is one of the most commonly used through-hole resistors. It is a 3-pin resistive chip resistor, which has a wide range of applications in electronics equipment. It is usually used in power electronic circuits as current and voltage limiting devices.

The RSF2GB3K30 is a 3-pin (2 pins + 1 ground pin) through-hole resistor that contains a thin-film, high precision resistive element. It has a wide resistance range of 3kΩ with a maximum operating temperature of +125°C and a maximum storage temperature of +160°C. The product has a maximum power dissipation of 1/4 Watt (250mW), a maximum voltage of 250V, and a tolerance of ±5%. It also features crushproof construction for durable use in the field.

The RSF2GB3K30 is most commonly used for current limiting in power electronic circuits, especially in over-current situations. It can also be used for voltage power limiting, as the device can be used as a voltage divider or a voltage limiting circuit. In addition, it can be used for component protection in surge environments, as well as protection of thermoelectric heaters in heaters and furnaces.

The working principle of the RSF2GB3K30 is relatively simple. When the applied voltage exceeds the device’s maximum voltage rating, the device’s resistance increases significantly, thereby limiting the current through the circuit. When the current is too high, this resistance increase further increases the resistance in the circuit, thus further limiting the current. In addition, the device has a positive temperature coefficient (PTC) which means that when the temperature increases, the resistance increases as well. This helps protect against over current surges and voltage transients.

The RSF2GB3K30 is a versatile through-hole resistor that is used in a wide range of applications. It is ideal for current limiting in power electronics circuits, as well as for basic current limitation in over-current situations. It is also a great choice for surge protection, voltage limiting, and component protection in surge environments. Additionally, the device has a positive temperature coefficient, which helps to protect against excessive current and voltage transients.
