Frequently Asked Questions (FAQs)

Question: Can I use a 4.7 ohm resistor in place of a 5 ohm resistor?
Answer: Yes, the 4.7 ohm resistor can be used as a close substitute for a 5 ohm resistor in most applications.

Question: What is the maximum voltage this resistor can handle?
Answer: This resistor can handle voltages appropriate for its power rating, typically up to around 50 volts.

Question: How do I determine the wattage rating required for my application?
Answer: Calculate the power dissipated by the resistor using P = V^2 / R, where V is the voltage across the resistor and R is the resistance value.

Question: Can I solder this resistor directly to a PCB?
Answer: Yes, soldering the resistor to a PCB is a common method of installation, ensuring a secure connection.

Question: What does the 5% tolerance mean?
Answer: The 5% tolerance indicates that the actual resistance of the resistor may vary by up to 5% from the specified value of 4.7 ohms.
