Through Hole Resistors are a common type of electronic components used in variety of applications. The RNF12GTD4K30 is one such component from the family of through hole resistors. This part is a small component containing a variety of layers with a single, solid piece of material in the middle. Its outer construction consists of a plastic layer, a copper conductor layer, tin-plated copper terminal layers, and a ceramic insulator layer.

The RNF12GTD4K30 is a resistor of the type 1206-sized chip resistor. Its electrical characteristics are 12 ohm (ohmic) tolerance, 2.4 volts max, 4 Kilo ohm nominal value, and 0.0035 dB dissipation factor. The resistor has a power rating of 0.1 Watts, an operating temperature range between -25 to +85 °C and an operating frequency range from DC up to ~10 MHz. It is a non-inductive (that is, does not contain an inductor) type of resistor that has that has low carbon composition.

The RNF12GTD4K30 through hole resistor is mainly used to regulate the flow of electrical current in a circuit. Its precise resistance and low dissipation factor provide a reliable and cost-effective solution to many circuit design problems. This type of resistor is also used in power electronics, automotive electronics, consumer electronics, and electrical appliances for the purpose of voltage and current control.

The working principle of a through hole resistor is simple. It is a passive type of component which creates a voltage drop across its terminals when an electrical current passes through it. This reduces the amplitude of the current, and the voltage drop across the resistor is referred to as its resistance. The resistance of a through hole resistor increases with increasing temperatures, and decreases with decreasing temperatures. The resistance also changes with the temperature coefficient which is determined by the material of which the resistor is constructed.

The construction of the RNF12GTD4K30 through hole resistor is quite simple. It has four layers— the plastic layer, the copper conductor layer, the tin-plated copper terminal layers, and the ceramic insulator layer. These layers are held together by adhesive, metal clamps, and rivets, and are typically about 1mm thick. The plastic layer provides protection against environmental conditions such as dust, dirt, and humidity, while the copper conductor layer provides electrical conduction, the tin-plated copper terminal layers provide excellent terminations, and the ceramic insulator layer provides insulation from the other layers.
