2.2k Ohm Resistor - (Pack of 10) The 2.2k ohm Carbon Film Resistors are typical axial-lead resistors, which have much better temperature stability and provide lower noise, and are generally better for high frequency or radiofrequency applications. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.

2.5mm Heat Shrink Tubing Black - 1  Meter A heat shrink tube (or, heat shrink tubing) is a tube that shrinks in diameter when heated. After being heated with a heat gun, it shrinks to 50% of its original diameter. Heat shrink sleeve with a completely thermoplastic covered interior surface. When heated, the sleeve's diameter shrinks by 2:1 and the interior resin melts. The sleeve and the resin harden as they cool. This combination ensures resistance to pullout and perfect waterproofing for your connections, preventing a sleeve from slipping. In the case of a connector mounted on a cable (coaxial, for example), this sleeving ensures reinforcement at the point where the cable is generally subject to stress when the radius of the curve is small. To protect the connection, the tubing is wrapped around it and heated with a lighter, matchstick, oven, hot air gun, or similar tool. A soldering iron (held close but not touching the tube) or the heat from a lighter are both convenient but ineffective methods for shrinking the tube. These processes cause the tubing to shrink to one-sixth of its original diameter (depending on the heat shrink, 2:1 is the most common), resulting in a tight fit over irregularly shaped joints. This provides good electrical insulation, dust, solvent, and other foreign material protection, and strain relief. Heat shrink tubing, like any other plastic, can melt, scorch, or catch fire if overheated. Key Features: Contracts when heated, durable thermoplastic interior. 2:1 shrink ratio for a tight fit, resistant to pullout. Ideal for cable stress points, and various heating methods. Suitable for wire protection, -40 to 125°C operating range. Tensile strength ?10.4 MPa, VW-1 flammability rated. Applications: Wire protection Joining Wires Electrical Insulation Cables and Wire bonding How to Use Heat Shrink Tubing
