NHL-225-07Z VISHAY Wire Wound Resistor

Review VISHAY Adjustable Wire Wound Resistor

The Vishay NHL-225-07Z wire wound resistor is a high-quality component designed for applications requiring precise electrical resistance values. This resistor, with the part number T228079, is a vital component in various electronic circuits due to its reliability and stability under different operating conditions.

The Vishay NHL-225-07Z is a 5% carbon composition wire wound resistor, which means it is made of a carbon-based material wound onto a ceramic or metal core. This design provides excellent temperature stability, making it suitable for applications where temperature changes may affect the performance of the circuit.

The resistor's nominal value is 225 ohms, with a tolerance of 5%. This means that the actual resistance value may deviate by up to 5% from the nominal value. The resistor has a power rating of 0.25 watts, which is suitable for low power applications. The maximum operating temperature of the Vishay NHL-225-07Z is 125 degrees Celsius, making it a reliable choice for applications that operate within this temperature range.

The Vishay NHL-225-07Z has a resistance temperature coefficient (RTC) of 0.0035 per degree Celsius. This means the resistance of the resistor changes by 0.0035 ohms for every degree Celsius change in temperature. This low RTC makes the resistor ideal for applications that require high accuracy and stability in the presence of temperature fluctuations.

The Vishay NHL-225-07Z is available in a T228 package, which is a compact, cylindrical shape with a height of 6.35 millimeters and a diameter of 3.2 millimeters. The resistor has a silver-plated copper alloy terminals for excellent electrical contact. The terminals are secured to the body of the resistor using a high-temperature epoxy compound, ensuring reliable operation even under harsh conditions.

In conclusion, the Vishay NHL-225-07Z wire wound resistor is a high-quality component designed for applications requiring precise electrical resistance values and temperature stability. Its 5% tolerance, low RTC, and compact T228 package make it an excellent choice for various electronic circuits, including automotive, industrial, and consumer electronics.

1. Reliability: Vishay is a well-established brand in the field of electronic components. Their products are known for their high reliability and durability.

2. Precision: This resistor has a tolerance of 0.1%, which means it can maintain a very close value to its specified resistance. This is beneficial in applications where high precision is required.

3. Power Rating: The power rating of this resistor is 1/8 Watt. This makes it suitable for low power applications.

4. Temperature Coefficient: The temperature coefficient of resistance (TCR) is -50 ppm/ C. This means the resistance value of the resistor changes very little with temperature changes, making it a good choice for temperature-sensitive applications.

5. Tinned Leads: The leads of this resistor are tinned, which provides excellent corrosion resistance and ensures easy soldering.

1. Size and Weight: Wire wound resistors are generally larger and heavier compared to other types of resistors. This can be a disadvantage in applications where space and weight are a concern.

2. Cost: Wire wound resistors are typically more expensive than other types of resistors due to their construction process.

3. Inconsistency in Resistance Values: Although the tolerance is 0.1%, there can still be some inconsistency in the resistance values due to the nature of wire wound resistors.

The Vishay NHL-225-07Z Wire Wound Resistor T228079 is a reliable and precise component suitable for low power and temperature-sensitive applications. Its tinned leads ensure easy soldering and its low TCR makes it a good choice for applications where temperature stability is important. However, its larger size and higher cost compared to other types of resistors are drawbacks that should be considered.

If you require a high precision, temperature-stable resistor for a low power application, the Vishay NHL-225-07Z Wire Wound Resistor T228079 could be a good choice. However, if size and cost are major concerns, you might want to consider other types of resistors.
