Through Hole Resistors

Through hole resistors (THRs) are a familiar type of resistor that has been around for many years. They are usually cylindrical in shape with a hole in the center into which a lead is inserted. The other end of the lead is usually soldered onto the circuit board. They are typically used to create low resistance barriers or paths to ground in circuits as they are very good at dissipating power.

THRs are typically made of either a metal or ceramic material. They are usually coated with a heat-resistant epoxy or Teflon which helps insulate them from the circuit board. The resistivity of the material determines their resistance value which is usually given in Ohms. Over time, THRs can accumulate debris or dirt on them which can alter their resistance values, so it is always best to clean them periodically.

The YR1B412RCC is a THR designed specifically for power levels of up to 1.2A. Its primary applications are in power switching circuits which require high-precision switching and current sensing. It is made of a ceramic material that is resistant to thermal shock and has an operating temperature range of -55 to +200°C. It isEpoxy-coated for added insulation and its resistance value is within ± 5% over its operating temperature range. It has a working voltage of 500V and a maximum power rating of 0.1W.

The working principle of the YR1B412RCC is relatively simple. In a circuit, current flows in and out of the design. When a voltage is applied across the THR, electric charges flow through it, effectively providing resistance to the flow of current. The amount of resistance is determined by the properties of the material used, such as its resistivity, and the size of the THR. As the current is forced to pass through the resistor, some of the electrical energy is converted to thermal energy which is released as heat.

Overall, the YR1B412RCC THR is a highly reliable, precise, and temperature-resistant device that is useful for power switching circuits, power supplies, and for providing high-precision current sensing. With its superior thermal shock resistance and consistent resistance values, it is ideal for applications where precision and stability are important requirements.
