Frequently Asked Questions:

Q: Can these 18 Ohm resistors replace a 1/2W resistor?
A: No, these resistors are rated for 1/4 Watt (0.25W). Replacing a higher wattage resistor with a lower one may cause overheating if power dissipation exceeds 0.25W.

Q: What is the lead pitch for these axial resistors?
A: The lead pitch for axial resistors is typically adjustable during through-hole mounting. Common board spacing allows for pitches between 10mm and 15mm.

Q: Do these resistors have a specific polarity for installation?
A: No, standard carbon film resistors are non-polarized and can be installed in either orientation within a circuit.

Q: What is the quantity included in this package?
A: This package contains 10 individual 18 Ohm 1/4 Watt Carbon Film Resistors.
