Through Hole Resistors are commonly used in electrical engineering, to provide reliable, stable, and accurate operating current. The development of resistors over the years has been significant, in terms of technology, materials, and components. The CFR-25JR-PN390R is an exemplar of such development, offering numerous advantages that outperform earlier generations of through-hole resistors.

The CFR-25JR-PN390R is a radial leaded heavy-duty through hole resistor that has a power rating of 25 watts at 500V. It has a higher Resistor/Inductor ratio than other resistors in its category, allowing it to operate in a wide range of temperature and load conditions. The resistor is designed to be used in DC or lower frequency AC circuits.

The CFR-25JR-PN390R has a high resistance-to-heat capacity ratio and has great tolerance and stability, due to its high wattage of 25 watts. It also has a low inductance and is free from PCB switching, making the resistor ideal for applications in high frequency AC and RF circuits. Its temperature coefficient is better than similar types of resistors, allowing for greater performance stability in extreme temperatures.

The benefits of the CFR-25JR-PN390R don’t stop at the component level. Its resistance value is crimped onto the leads, making it mechanically secure and resilient to shock and vibration. Its long-term reliability is further insured by the use of ceramic insulation, which provides superior protection against aging and wear.

When it comes to application areas, the CFR-25JR-PN390R is predominantly used for pulse shaping, energy management and power management in a wide range of industries, including medical equipment, automotive electronics, security systems, industrial applications, HVAC systems, and more. High-frequency applications such as transceivers and high-end routers also benefit from the improved stability and accuracy of the CFR-25JR-PN390R.

The working principle behind the CFR-25JR-PN390R is relatively simple. It works much like any other through-hole resistor. Electrons flow through the resistor when a current is applied, resulting in a voltage drop across the contact. The resistance of the resistor can be varied by adjusting its length and width in order to control the amount of current. The heat generated by the resistor plays an important role in regulating its temperature, which is further amplified by the use of ceramic insulation.

In conclusion, the CFR-25JR-PN390R is an example of a high-performance through-hole resistor. It offers a reliable and accurate power source in applications that require high power density and low inductance. Its mechanical strength, temperature coefficient, and thermal resistance also make it an ideal fit for various industries.
