Unique Bargains 1Ohm to 9.1Ohm Metal Film Resistor Assortment Kit 21 Value 1W 1% Tolerance, 105 Pack

Metal film fixed resistors are cylindrical axial resistors with a thin metal layer as the resistive element on a non-conducting body. They are used when a high tolerance or more accurate value is needed in a circuit, also used for bridge circuits, filter circuits, and low-noise analog signal circuits. Wide operating range, long-term stability, low tolerance, low noise, and low-temperature coefficient of resistance i.e. the resistance does not change quickly with a change in temperature. Resistors are non-polar, meaning they don't have a direction: you don't have to worry about putting it in 'backward' because they work the same either way. Always read resistors from left to right. While resistors don't have their polarity they will typically be part of a circuit that does, thanks to other components like capacitors.
