Through Hole Resistors have been used in electronic circuits for a variety of tasks, from creating a voltage divider to attenuating signals to protecting circuits against overvoltage. The NSM10AJB-51R is one such component, a through hole resistor of considerable power rating.

The NSM10AJB-51R is an axial lead resistor, which means its electrical contacts protrude from both ends of its cylindrical body. The electrical contacts are designed to be inserted into the PCB through holes with the necessary electrical connections, which is why the component is classified as through hole resistor. On the outer body of the resistor there are several components which indicate the resistor’s characteristics and capabilities, including its resistance, power rating, and tolerance.

The resistance of the NSM10AJB-51R is the first chracteristic its owner needs to be aware of, as it will determine the component’s behavior within an electrical circuit. When building a circuit, the resistor’s resistance will depend on the electrical current that components within the circuit generate. This electrical current is how the resistor is able to resist subtracted components in a circuit, so correctly identifyng its resistance value is critical in choosing an appropriate resistor. The NSM10AJB-51R has a resistance of 10 ohms.

The power rating of a resistor is measured in watts and indicates the amount of power the resistor can handle without overheating. The NSM10AJB-51R has a power rating of 1/2 Watt (500 milli watts), which means it can safely dissipate heat up to 500 milli watts without overheating and becoming damaged. Increasing the wattage will cause the resistor to heat up, so the power rating should always be observed, and when in doubt a higher wattage should be tried.

The last chracteristic of the NSM10AJB-51R is its tolerance, which is a measure of how much variability the manufacturer is willing to allow with regards to its resistance value. The NSM10AJB-51R has a tolerance rating of ±5%, which means its resistance value can vary up to 5% from the stated value of 10 ohms. This is within the standard tolerance range of for most axial lead resistors.

Having identified the characteristics of the NSM10AJB-51R, its various applications can now be discussed. Generally, resistors are used to reduce current or voltage levels in circuits, such as in voltage divider circuits or as current-limiting elements. Additionally, it can also be used to reduce electrical noise by attenuating high-frequency signals, or to increase the stability of LED circuits. The NSM10AJB-51R is particularly suited for these applications due to its relatively high power rating and tolerance.

The NSM10AJB-51R has a standard working principle for axial lead resistors. When the electrical current enters the contacts of the resistor, it is subjected to the resistor’s resistance. The resistance creates a voltage drop across the resistor, and this in turn creates a corresponding decrease in the electrical current. The decrease in current is proportional to the resistor’s resistance, so the higher the resistance, the greater the decrease in current.

In summary, the NSM10AJB-51R is an axial lead resistor that is classified as a through hole resistor, due to its construction. The resistor has a resistance rating of 10 ohms, a power rating of 1/2 Watt, and a tolerance rating of ±5%. Its primary application is to attenuate high-frequency signals, reduce current or voltage levels in a circuit, or increase the stability of LED circuits. Its working principle is the same as all axial lead resistors. The resistor creates a voltage drop across its internal resistance, causing a decrease in the current passing through it.
