Shrinking in size throughout the decades to accommodate various products and machinery, many electronics now pack more capabilities while in the form of a smaller package. Packing just as much punch as compared to older, larger model electronic equipment, parts like resistors have become discrete and serve as the backbone to many circuits. As two-terminal electrical components that impose an electrical resistive force, resistors are designed to be a part of a circuit assembly as monitoring tools. Used to adjust signal levels, current flow, divide voltages, bias active elements, terminate transmission lines, and a plethora of other helpful tasks, resistors are ubiquitous in electronics and necessary for safely affecting current.
Present in almost every circuit, resistors are parts that operate off of Ohm’s Law. As such, a resistor's primary goal is to retain a stagnant resistance level, ensuring flow is limited to an exact level when current is present in a system. Passive in capabilities, these parts do not consume excess energy and only function when current is actively running through a network. You can find resistors in action that commonly come complimented with op-amps, microcontrollers, and numerous integrated circuit parts.
Built with two terminals to facilitate the passage of electrons from one circuit to another, resistors come in a variety of types for optimal mounting and placement. Ordinary resistors include: static resistors, a pack of resistors, resistors for particular variables, and standard resistors. Of the potential resistor options available, all types will either be present with PTH (plated through-hole) or SMD/SMT (surface-mount technology or device) termination and mounting devices. Equipped with pliable beads best for hand soldering or insertion into breadboards, PTH mounted resistors are optimal for breadboarding, prototyping, or where soldering of tiny components is not recommended. However, unlike PTH parts, SMD/SMT resistors are meant to terminate the end of a current line. Soldered to PCBs (printed circuit boards) for easy mounting, these parts are tremendously tiny and require robot-guided precision for accurate and optimal part placement.
Constructed out of different materials to achieve a myriad of resistance capabilities, most modern resistors are made from metal, carbon, or metal-oxide films. To make a resistor for a particular network application, a conductive material with resistive properties is shaped into a helix and covered with an insulating material. SMD/SMT resistors typically utilize super thin sheets of a metal alloy which are sandwiched between a ceramic base, then coated in a glass or epoxy solution before being inserted to terminate a line. For more specialized solutions, pre-wired resistors are also available with five or more resistors which can be applied as voltage dividers.
When current is not stagnant or multiple variables must be considered, resistors with adjustable qualities are needed. Like rheostats, potentiometers, and other adjustable resistors, these parts can be set to monitor specific current values and are used for adjustable knobs (i.e. volume knobs) and other input devices.
