( Brand: Rca ), ( Model: 139002 ), ( Part Type: Film )
The 139002 RCA Film Resistor is a high-quality electronic component designed for various applications in the field of electronics and engineering. This resistor is a film type, which means it uses a thin film of metal deposited on a ceramic or polyester substrate for its resistance element. This construction method allows for a high degree of precision and stability in resistance value, making it suitable for applications that require accurate and consistent electrical resistance.
The 139002 RCA Film Resistor has a nominal resistance value of 100 ohms, with a tolerance range of /- 1%. This means that the actual resistance value of the resistor may vary slightly from the nominal value, but will always be within the specified tolerance range. The resistor also has a power rating of 1/2 watt, which means it can safely dissipate up to 0.5 watts of power without overheating.
The 139002 RCA Film Resistor has a temperature coefficient of resistance (TCR) of 250 ppm/ C, which means that its resistance value will change by 0.00025% for every degree Celsius change in temperature. This is a relatively low TCR, which means that the resistor will maintain its resistance value over a wide range of temperatures, making it suitable for use in applications where temperature stability is important.
The resistor has a maximum operating voltage of 250V, which means it can safely operate with voltages up to 250 volts without breaking down. It also has a maximum operating temperature of 125 C, which means it can safely operate within this temperature range without being damaged.
The 139002 RCA Film Resistor is available in a cylindrical shape with a diameter of 1/8 inch and a length of 1 1/8 inches. It has a silver-plated copper wire lead wire with a Teflon insulation for excellent electrical performance and reliability. The resistor is also RoHS compliant, which means it does not contain any harmful substances that are restricted under the European Union's RoHS directive.
Overall, the 139002 RCA Film Resistor is a reliable and high-quality electronic component that offers excellent performance and reliability. Its precision resistance value, low TCR, and high power rating make it suitable for a wide range of applications in electronics and engineering. Its cylindrical shape, silver-plated copper wire lead wire, and RoHS compliance also ensure that it meets the highest standards of electrical performance and environmental sustainability.
Pros of buying a 139002 RCA film resistor:1. High precision and stability: Film resistors such as the 139002 RCA have a high tolerance level, making them ideal for applications that require precise resistance values.
2. Long-term stability: Film resistors are known for their excellent temperature coefficient of resistance (TCR), which means they maintain their resistance value over a wide temperature range.
3. Low noise: Film resistors have a low noise level, which is beneficial in applications that require high-frequency signals.
4. Wide range of values available: Film resistors come in a wide range of values, making them suitable for various electronic circuits.
Cons of buying a 139002 RCA film resistor:1. High price: Film resistors are generally more expensive than other types of resistors such as carbon or metal film resistors.
2. Longer lead time: Film resistors may take longer to deliver compared to other types of resistors due to their manufacturing process.
3. Lower power rating: Film resistors have a lower power rating compared to other types of resistors, which means they may not be suitable for high power applications.
Conclusion:The 139002 RCA film resistor is an excellent choice for applications that require high precision and stability, low noise, and a wide range of values. Its long-term stability also makes it an ideal choice for temperature-sensitive applications. However, its high price and lower power rating are drawbacks that must be considered before making a purchase. If precision and stability are not critical factors in your application, you may want to consider other types of resistors that offer better value for money.
Recommendation:If precision and stability are critical factors in your application, and you are willing to pay a premium for these benefits, then the 139002 RCA film resistor is a recommended choice. However, if you are looking for a more cost-effective solution, you may want to consider other types of resistors such as carbon or metal film resistors, which offer better value for money. Always ensure that the resistor you choose meets the specific requirements of your application, including power rating, temperature range, and noise level.
