Frequently Asked Questions:

Q: Can a 2.2 Ohm 1/4W resistor replace a 2.2 Ohm 1/2W resistor?
A: These resistors are rated for 1/4 Watt. Replacing a higher wattage resistor with a lower wattage resistor may result in component failure if power dissipation limits are exceeded.

Q: What is the maximum voltage rating for these resistors?
A: The maximum working voltage is 250V, and the maximum overload voltage is 500V.

Q: Are these carbon film resistors polarized?
A: No, carbon film resistors are non-polarized components and can be installed in either direction.

Q: What are the physical dimensions of the resistor body?
A: The body dimensions are approximately 2.3mm (Diameter) x 6.3mm (Length).
