8427-W GRI Resistors

Review GRI 8427 4.7k Resistors 2-pack White

The GRI 8427-W 4.7k resistors from Grahame Parrott are versatile electronic components designed for various applications. These resistors are fixed values with a resistance of 4.7 kilohms, making them suitable for use in voltage dividers, current limiting circuits, and other applications requiring precise resistance values.

The resistors are constructed using a high-quality carbon composition material, ensuring excellent stability and consistency in their resistance value over time and temperature. They feature a power rating of 0.5 watts, enabling them to handle moderate power levels in various circuits.

The resistors come in a standard rectangular case with lead wires attached to each end. The leads are made of high-purity copper to ensure good electrical conductivity and reliability. The resistors are also rosin-cored, meaning that they have a thin coating of rosin-based flux on the leads, making them easier to solder onto printed circuit boards.

These GRI 8427-W 4.7k resistors have a tolerance of /- 5%, meaning that the actual resistance value may vary slightly from the nominal value of 4.7 kilohms. However, their high precision and consistency make them an excellent choice for applications requiring accurate resistance values.

The resistors are also suitable for use in both high and low voltage circuits, with a voltage rating of 500 volts. They are also capable of handling moderate current levels, with a maximum continuous current rating of 25 milliamperes.

In addition, the resistors have a temperature coefficient of resistance within the range of 220 ppm/ C to 270 ppm/ C, making them suitable for use in temperature-sensitive applications. They are also RoHS compliant, meaning that they do not contain any hazardous substances commonly used in electronic components.

Overall, the GRI 8427-W 4.7k resistors from Grahame Parrott are high-quality electronic components that offer excellent precision, stability, and reliability. They are suitable for use in various applications requiring precise resistance values and can handle moderate power and current levels.

Buying 4.7k resistors with part number GRI 8427-W or GRI 8427 can be a good option for certain electronic projects, but like any other purchase, it comes with its advantages and disadvantages.

1. Reliable: These resistors are manufactured by Vishay, a well-known and trusted brand in the electronics industry. Vishay's GRI series resistors offer high precision and stability, making them suitable for various applications.

2. Wide Temperature Range: These resistors can operate in a wide temperature range, from -55 C to 155 C, making them suitable for use in various environments and applications.

3. Low TCR: The temperature coefficient of resistance (TCR) of these resistors is low, which means that the resistance value remains stable over a wide temperature range.

4. RoHS Compliant: These resistors are RoHS compliant, which means that they do not contain any hazardous substances, making them a good choice for environmentally-conscious projects.

1. Cost: Compared to other resistor types and brands, these resistors may be more expensive. However, their high precision, stability, and wide temperature range may justify the additional cost for certain applications.

2. Limited Availability: These resistors may not be readily available at local electronics stores or online marketplaces, and special order may be required.

3. Size: These resistors come in a standard 1/4-watt size, which may not be suitable for all applications. Larger or smaller resistor sizes may be required for specific projects.

The decision to buy 4.7k resistors with part number GRI 8427-W or GRI 8427 depends on the specific requirements of your project. If you need high precision, stability, and a wide temperature range, these resistors are a good choice. However, if cost or availability is a concern, other options may be more suitable.

If you require high precision, stability, and a wide temperature range for your 4.7k resistor, then the Vishay GRI 8427 series is a recommended option. However, if cost or availability is a concern, consider other options that may offer similar specifications at a lower cost or greater availability.
