THROUGH HOLE RESISTORS

Through Hole Resistors are among the most commonly used resistors in the electronic component industry. The 42J47RE is a metal-oxide film resistor, typically available in packages of 35 values from 47 ohm to 6.57k ohm. This model incorporates an increased power rating of 5W, while still providing the same exceptional performance characteristics.

Application Field

The 42J47RE is mainly used for DC applications in consumer electronics, communications equipment, motor controls and industrial systems. The superior temperature rise and high power rating makes it suitable for a range of applications with increased power requirements. It is designed for increased power handling capacity in a smaller footprint, while still providing the very best in reliability with low ESR. It is also extremely durable, due to its unique construction, making it a good choice for long-term performance in demanding environments.

Working Principle

The working principle of the 42J47RE is simple. It is made up of a metal-oxide film resistor formed on a ceramic substrate, which is covered by a metal protective layer. The film resistor is then connected to two leads, one of which is connected to a positive voltage and the other is connected to a negative voltage. When a current is applied to the leads, the electric field created by the current causes the metal-oxide film to become resistive, creating a resistance. This resistance is then used to regulate the amount of current passing through the circuit.

The 42J47RE also provides an excellent thermal shock resistance, ensuring long-term reliability even in hostile environments. The resistor features a low EMI emission, providing a high level of electromagnetic interference protection. It also features an excellent frequency response and a low inductance, meaning the response time is faster and less inductive impedances can be achieved.

Conclusion

The 42J47RE is a through-hole resistor with an increased power rating while still providing exceptional performance. It is suitable for DC applications in consumer electronic, communications equipment, motor controls and industrial systems. It also features an excellent thermal shock resistance, a high level of EMI emission protection and a low inductance for faster response times. Its high performance characteristics make it a perfect choice for a range of applications.
