5pcs: 18 ohm [18e : 18R] 18e 1/2 Watt Resistor [0.5W] CFR

18 Ohm 0.5W Carbon Film Resistor (CFR), 5 Pieces

This package contains five 18 Ohm 0.5W Carbon Film Resistors (CFR). Each resistor provides a nominal resistance of 18 Ohm. The power dissipation rating is 0.5W. These components are utilized for current limiting, voltage division, and signal conditioning. Carbon film resistors exhibit stable performance characteristics. The axial-leaded design allows for integration into circuit boards. This set supports prototyping, repair, and general circuit design requirements.

Frequently Asked Questions:

Q: Can these 18 Ohm 0.5W CFR resistors replace a 0.25W resistor?
A: Yes, a 0.5W resistor can replace a 0.25W resistor of the same resistance value, provided physical dimensions are compatible. The higher wattage rating indicates greater power dissipation capability.

Q: What is the typical lead pitch for these axial-leaded resistors?
A: Standard axial-leaded resistors of this wattage typically have a lead pitch compatible with common breadboards and PCB hole spacing, often around 10-15mm when bent for through-hole mounting.

Q: Are these 18 Ohm resistors polarized?
A: No, resistors are non-polarized components and can be installed in either orientation within a circuit without affecting their function.

Q: How does the 5% tolerance affect the actual resistance value?
A: A 5% tolerance on an 18 Ohm resistor means its actual resistance value will be between 17.1 Ohms (18 - 5%) and 18.9 Ohms (18 + 5%).
