Through hole resistors have been used in the electronics industry since the 1940s. Resistor technology has evolved over the years, and today one of the most popular varieties of resistor used in various fields is the “FRN25J10R” through hole resistor. This resistor is used for a range of applications, from general replacement to high-reliability fault-finding solutions.

The FRN25J10R is a small axial-leaded resistor, measuring about 6.25mm in length and 0.3 mm in width, not including the leads. It has a resistance of 10 Ohms, at a maximum wattage of 1/4 Watt. It has a power rating of only 1/16 watts, which makes it a good choice for applications where space is at a premium but a low power requirement is needed.

The resistor\'s body is typically made of ceramic, and the leads, which are either nickel or tin-plated copper, are attached to its body. It is rated at a temperature co-efficient of 100, which means that it retains its value over a temperature range of -55 C to +125 C. The resistor is also RoHS (Restriction of Hazardous Substances) compliant, which makes it safe for use in many electronics applications.

The FRN25J10R is primarily used as a high-value resistor in circuit designs. It can be used for signal attenuation, current limiting, temperature compensation, and voltage regulation. It can also be used as a termination network in backplane applications, and for reaching minute voltage coefficients or low power requirements. In addition, it may also be used as a current-sensing resistor for over-voltage protection in automotive systems.

The working principle of the FRN25J10R is relatively simple. It has a small metal layer, typically a tin-plated nickel, which forms a thin layer against the resistive material, typically carbon or a nickel-chromium alloy. As current passes through the resistor, ions from the resistive material move between the metal layer and the resistive material, creating an electric field that causes friction, which, in turn, generates heat. This heat is dissipated from the resistor, resulting in a change in the resistive value.

The FRN25J10R through hole resistor is ideal for use in a variety of electronic applications, from general replacement to fault-finding solutions. It is small in size, low in power rating, and rated with a high temperature co-efficient, making it an ideal choice for applications where space is at a premium but a low power requirement is needed. Its working principle is also relatively simple and straightforward, making it an excellent choice for electronics applications.
