Through Hole Resistors are a type of resistors that can be fixed to a board with an edge connector as their main purpose in an electrical circuit is to dissipate or resist the flow of electric current. The MK1273FE-R52 is a premium Through Hole Resistor from the MK12 series of products and offers superior performance even in the most demanding of applications. This article will introduce the application field and discuss the working principle of the MK1273FE-R52.

The MK12 series of Through Hole Resistors is designed for high power applications that require extremely low ohms of resistance. The MK1273FE-R52 is a high power variant with a 4-terminal configuration for connecting to a circuit board. It is ideal for applications such as power amplifiers, high power transmitters, and switch mode power supplies. The MK1273FE-R52 can handle up to 12 amperes of continuous current at altitude of up to 2000m (6560ft) and temperatures of up to +90°C (+194°F), and is certified to meet EN60950/UL1950 requirements. In addition, its extended frequency range makes it a desirable choice for applications that require significant pulses.

The MK1273FE-R52 features a ceramic substrate, which provides superior heat dissipation and resistance to thermal shock. The resistor\'s superior dielectric properties make it ideal for use in high power applications where there is a risk of current spikes or induced signals. The high quality ceramic substrate ensures excellent electrical contact between the resistor and the board, while the heavy walled leads provide enhanced mechanical stability and vibration resistance for the device. Furthermore, the MK1273FE-R52 is RoHS compliant, making it an attractive option for those looking to reduce their environmental footprint.

The MK1273FE-R52 utilizes a unique resistive construction in which a thin film is applied on the ceramic substrate. This thin film is composed of an aqueous solution of metal conductive particles, which provides a uniform resistance throughout the resistor. The electrical current is drawn through a series of protrusions or pads on the resistor which creates a voltage drop, converting the electrical current into heat. The heat is dispersed through the ceramic substrate and to the surrounding environment, thereby dissipating the current and allowing it to be controlled.

The MK1273FE-R52 is an ideal choice for a variety of applications, as it offers superior performance and reliability even in the most demanding of applications. Its superior resistive construction and RoHS compliance make it an attractive option for those looking to reduce their environmental footprint. Furthermore, the ceramic substrate also provides superior heat dissipation and resistance to thermal shock. Finally, its extended frequency range makes it a desirable choice for applications that require significant pulses. The MK1273FE-R52 is thus the perfect choice for high power applications that require extremely low ohms of resistance.
