Wattage: "1/2 watt" indicates the power rating of the resistors. It means that each resistor in the assortment can handle up to 1/2 watt (0.5 watts) of power without overheating or getting damaged.
CFR: CFR stands for "Carbon Film Resistor." Carbon film resistors are one of the most common types of resistors used in electronic circuits. They are made by depositing a thin layer of carbon film onto a ceramic core.
5%: The "5%" represents the tolerance of the resistors. In this case, it means that the resistors have a tolerance of 5%. Tolerance refers to the acceptable variation in resistance value from the specified or labelled resistance value. A 5% tolerance indicates that the actual resistance of each resistor can vary by +/- 5% from its stated value. For example, if the labelled resistance is 100 ohms with a 5% tolerance, the actual resistance of that particular resistor can be anywhere between 95 ohms and 105 ohms.
