PFR5K11RO OHMITE Resistor

Review OHMITE Resistor

The Ohmite PFR5K11RO resistor, with the part number T216923, is a high-performance power resistor designed for a wide range of applications. This resistor is a part of Ohmite's PFR (Power Fuse-Rated) series, which is known for its robust construction and reliable performance under high power and temperature conditions.

The Ohmite PFR5K11RO is a 5 watt, 5.0 ohm resistor, and it is available in a versatile 1/8th watt, 3-terminal, TO-220 package. The TO-220 package is a standard, industry-recognized package that provides excellent thermal dissipation, making it an ideal choice for power resistors.

One of the key features of the PFR5K11RO is its fuse-rated design. This means that the resistor is specifically engineered to protect downstream components from excessive currents. The resistor's fuse rating is 10A, which ensures that in the event of an overcurrent situation, the fuse will blow, protecting the rest of the circuit.

The Ohmite PFR5K11RO is made with Ohmite's proprietary alloy, which is known for its excellent electrical and thermal properties. This alloy allows the resistor to maintain its resistance value over a wide temperature range, from -55 C to 200 C. The resistor also has a high power factor, which means that it can dissipate heat more efficiently, reducing the risk of thermal runaway and ensuring reliable operation.

The Ohmite PFR5K11RO is RoHS compliant and is available with Teflon coating or silkscreened markings for easy identification and legibility. The resistor's high power rating, fuse-rated design, and robust construction make it an excellent choice for applications where reliability and safety are critical, such as power electronics, motor control, and industrial automation.

In summary, the Ohmite PFR5K11RO is a high-performance power resistor that offers excellent electrical and thermal performance, fuse-rated protection, and a versatile TO-220 package. Its robust construction, reliable operation, and RoHS compliance make it an ideal choice for a wide range of power electronics and industrial applications.

1. High Power Rating: This resistor has a power rating of 5 Watts, which means it can handle a significant amount of power without overheating.

2. Temperature Coefficient: The PFR5K11RO resistor has a low temperature coefficient of resistance (TCR) of 150 ppm/ C, which means its resistance value changes only slightly with temperature changes.

3. Wide Operating Temperature Range: The resistor has a wide operating temperature range of -55 C to 150 C, making it suitable for use in a variety of environments.

4. RoHS Compliant: The Ohmite PFR5K11RO resistor is RoHS compliant, which means it does not contain harmful substances such as lead, mercury, and cadmium.

1. Limited Availability: This resistor may not be readily available in all electronic stores, and you may need to order it online or from a specialized supplier.

2. Higher Cost: Compared to cheaper resistors, the Ohmite PFR5K11RO may be more expensive due to its high power rating and low TCR.

Conclusion: The Ohmite PFR5K11RO resistor T216923 is a high-quality resistor with a wide operating temperature range, low TCR, and high power rating. Its RoHS compliance and availability may be limited, but the benefits it offers, such as improved performance and reliability, can outweigh these drawbacks for some applications. If the cost is not a major concern, this resistor can be a good choice for applications that require high power handling and temperature stability.

Recommendation: If you are looking for a high-performance resistor with a low TCR and high power rating, the Ohmite PFR5K11RO resistor T216923 is a good option to consider. However, be sure to check its availability and compare its price with other options to ensure it is the best fit for your specific application and budget.
