Through hole resistors are among the most widely used passive components in large-scale electronic circuits. In the past two decades, resistor technology has improved significantly, and integrated resistors have become increasingly smaller, yet packing more and more power. The 42J20RE application field and working principle are a perfect example of the capabilities of today’s integrated resistors.

The 42J20RE is a resistor designed for high-power applications. Like all resistors, it serves the function of limiting current within an electronic circuit. It works on the principle of heat dissipation, allowing the current passing through it to be dissipated as heat rather than flow directly into the circuit. In this way, the 42J20RE prevents the circuit from being overloaded and damaging the sensitive components within.

In terms of application fields, the 42J20RE is particularly well-suited for applications such as circuit breakers, motor drives, rectifiers, and broadband amplifiers. Its wide resistance range (20.5 to 31.9 ohms) allows it to be used in a broad range of applications, from consumer electronics to industrial automation.

The 42J20RE also stands out for its exceptional power handling capabilities. It has a resistance rating of 0.4 to 0.95 Ohm, making it well-suited for higher-power applications. The 42J20RE also has an ideal thermal dissipation rate of 1.5W/°C, allowing it to dissipate heat efficiently and minimize the risk of circuit overload.

As with all modern resistors, the 42J20RE is designed to be highly reliable and long-lasting. It is constructed using a two-piece ceramic and thermoplastic construction, which enables it to withstand extreme levels of high temperature and current. The 42J20RE is also designed to withstand instantaneous voltage transients up to 4.5V. This makes it an ideal choice for large power applications where sudden surges of power can occur.

In summary, the 42J20RE is an ideal choice for a variety of high-power applications requiring reliable and long-lasting resistors. Its wide resistance range, exceptional power handling capabilities, and proven reliability make it an ideal choice for any application that needs to control or limit current efficiently. As a result, the 42J20RE is a perfect example of the capabilities of today’s integrated resistors.
