Through hole resistors are often used in applications which need a higher power rating or physical installation depth then what can be achieved with an SMT component. The MFR25SFTE52-187K through hole resistor is an excellent solution for when a larger power rating or enhanced vibration resistance is needed. The MFR25SFTE52-187K has an extended temperature range, making it suitable for a wide variety of applications. In this article, we will discuss the application fields and working principles of the MFR25SFTE52-187K.

Application fields

The MFR25SFTE52-187K through hole resistor’s extended temperature range make it suitable for a variety of different applications. It is commonly used for industrial automation, medical equipment, lighting, and telecom industry. It is also a good choice for automotive and military applications, as its extended temperature range reduces the need for multiple voltage ratings.

The MFR25SFTE52-187K is also frequently used as a voltage detector, as it can detect a variety of levels of voltage, from low to high. Its extended temperature range makes it an excellent choice for applications that require a very precise voltage detection. Additionally, the MFR25SFTE52-187K’s quality components ensure a long lifespan, making it an excellent option for long-term projects.

Working Principle

The MFR25SFTE52-187K operates on a thermistor principle. A thermistor is a sandwich type package composed of two copper discs with an insulating material between them. When a current passes through the copper discs, the heat generated from the current causes the insulating material to expand and contract in proportion to the temperature. The disk with the higher resistance releases more heat resulting in greater contraction. This creates a potential difference, thus creating a voltage across the disk.

The MFR25SFTE52-187K employs this thermistor principle to provide an accurate and precise indication of the voltage present. An even greater accuracy can be achieved by using a temperature compensated thermistor. By combining a temperature probe and thermistor, the temperature of the thermistor can be monitored, thus allowing for more precise voltage detection.

The MFR25SFTE52-187K is also shockproof and is designed to handle both high and low temperatures. Its construction includes a ceramic core, a polyimide carrier substrate, and a zinc metal casing which provides environmental making it suitable for use in harsh conditions. Additionally, the MFR25SFTE52-187K has a self-resistor material which ensures that the resistance does not change with time and is unaffected by temperature variations.

In conclusion, the MFR25SFTE52-187K through hole resistor is an excellent choice when a higher power rating, enhanced vibration resistance, and accurate voltage detection are needed. With its extended temperature range, shockproof design, and self-resistor material, the MFR25SFTE52-187K is suitable for a wide variety of applications, including industries such as industrial automation, medical equipment, lighting, and telecom.
