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.Specification:Body Color: BlueMaterial: Metal Film, Electronic PartsTolerance: ±1%Power: 2 Watt (2W)Dimension: 15x5mm (L*Dia.)Fix Resistance Values: 100Ohm, 120Ohm, 150Ohm, 180Ohm, 200Ohm, 220Ohm, 240Ohm, 270Ohm, 300Ohm, 330Ohm, 360Ohm, 390Ohm, 430Ohm, 470Ohm, 510Ohm, 560Ohm, 620Ohm, 680Ohm, 750Ohm, 820Ohm, 910OhmPacking List: 105 x Metal Film Resistors (5pcs for Each Value)Advantage: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.Instruction: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.Notice:Metal film resistors are unsuitable for applications that expose them to surge transients. While resistors don't have their polarity they will typically be part of a circuit that does, thanks to other components like capacitors.
