Through Hole Resistors

Through hole resistors provide the electrical resistances needed to appropriately control currents traveling through circuits. The presence of an external resistor helps to ensure these currents remain at their desired level. The RN55E3121BRE6 is an example of a through hole resistor.

RN55E3121BRE6 Application Field

The RN55E3121BRE6 through-hole resistor is used for applications in industrial control and military communication. Its semiconductor performance ensures the reliability of any circuit built with it.

RN55E3121BRE6 resistors are especially helpful in situations where comprehensive, reliable protection of said circuits is needed. Such situations can include places where a circuit is exposed to extreme temperatures, as the resistor\'s high-resistant gold-plated surface can cope with up to -55°C to +145°C temperature range.

The RN55E3121BRE6 is suitable for both high- and low-power applications, with its rated power of AWG 1/4W (0.25 Watt) able to control current waves of up to 70 KHz.

RN55E3121BRE6 Working Principle

The working principle of the RN55E3121BRE6 revolves around its ability to restrict the passage of electric current flowing through it, hence functioning as a resistor. It does this by converting electrical energy into heat, which helps prevent the current from surpassing its set values and damaging other integrated circuits in the circuit.

The RN55E3121BRE6 helps achieve this through its materials; these resistors are made of a mixture of ceramic and silver, both of which have good electrical insulating properties.

The ceramic component helps ensure that any electromagnetic interference (EMI) present in the circuit remains filtered, while the silver component helps to enhance electrical and mechanical stability. The silver-ceramic resistor setup effectively ‘forms a barrier’ against high-frequency noise, meaning it only passes through the resistor and is not reflected back to the source.

The gold-plated surfaces of the RN55E3121BRE6 through-hole resistor also make them corrosion-resistant, thus providing protection against moisture ingress.

Conclusion

The RN55E3121BRE6 is a versatile high-performance through-hole resistor, designed for reliable operation in extreme temperatures and resistant to both high-frequency noise and EMI. Its gold-plated surfaces also give it excellent corrosion resistance and further enhances its performance. As such, these resistors are perfect for power and industrial control applications, as well as military communication.
