LR0204F130R

Through Hole Resistors

One of the most common types of resistors used today is the through hole resistor. Through hole resistors are designed to be mounted in a printed circuit board (PCB) and use leads for interconnection with other components. The size and shape of through hole resistors vary, but in general they are quite small in comparison to the PCB they are mounted in. The main advantage of through hole resistors is that they have the ability to dissipate heat energy more effectively than their surface mount counterparts, and also allow for better signal performance due to the extra space between components.

LR0204F130R Application Field and Working Principle

The LR0204F130R through hole resistor is a type of radial leaded device specifically designed to be used in demanding surge and vibration applications. This type of resistor has a wide range of applications, such as power supply line protection, EMI/RFI suppression, and as a voltage divider. It is particularly suitable for positioning in densely populated PCBs and making contact with an array of other components, as it has the capability of both dissipating and withstanding a multitude of different surge and power configurations.

The LR0204F130R consists of two metal components, the anode (positive) and cathode (negative), which are connected in parallel. A ceramic (e.g. porcelain, quartz, or non-organic) resistive element is placed between the two metal components. This ceramic resistive element, or dielectric, has a fixed electrical insulating capability that reduces the flow of current in the circuit. In addition, the LR0204F130R also has two terminals (anode and cathode) that are physically separated by a gap or space in order to minimize the effect of stray leakage currents.

The LR0204F130R is manufactured with various specifications and wattage ratings, ranging from 1W to 10W. In addition, various types of package sizes are available, with the most common being TO-220 and TO-247 formats. The maximum recommended temperature of the resistor is +150°C, making it suitable for a wide range of uses. It also has a wide range operating voltage of 0 to 250 VDC.

The working principle of the resistor works as follows: when a current is passed through the device (e.g. through the anode and the cathode), the resistance creates a potential difference in the circuit that hinders the flow of the current. This potential difference, also referred to as voltage drop, is dependent on the amount of current that is passing through the resistor. The resistance of the LR0204F130R would also determine the amount of power (in Watts) that can be dissipated.

In summary, the LR0204F130R is a type of through hole resistor designed for high vibration and surge protection applications. Its ability to dissipate heat efficiently and withstand a variety of power configurations make it a suitable choice for multiple uses. Furthermore, its wide range of wattage ratings and package sizes allow it to be easily integrated and mounted in a PCB.
