Resistor, abbreviated as resistor (resistor, usually denoted by "R"), is the most frequently used component in all electronic circuits. The main physical characteristic of a resistor is that it converts electrical energy into heat energy, meaning it is an energy-consuming component, and internal energy is generated when current passes through it. Its primary function is to obstruct the flow of current and is used for current limiting, voltage dividing, voltage dropping, load handling, cooperating with capacitors for filtering, and impedance matching. In digital circuits, its functions include pull-up and pull-down resistors.

Thick-film resistors mainly refer to resistors made using thick-film printing technology.

These resistors can be rectangular, strip-shaped, curvature-shaped, or other forms.

They are commonly used in the manufacture of precision resistors and power resistors.

Common thick-film resistors are made by printing and sintering a metal-ruthenium based resistor paste.

The resistor paste contains ruthenium oxide, organic solvents, and glass beads.

After sintering, the resistor consists of two components: the resistance of the ruthenium oxide itself and the barrier resistance.

Resistors in circuits usually play the role of voltage division and current splitting. Both AC and DC signals can pass through resistors. When working in high-temperature environments, it is necessary to select resistors that can withstand higher temperatures and remain stable, such as metal oxide resistors. Accuracy and tolerance refer to the range of deviation in resistor values. In some high-precision applications, resistors with smaller tolerances need to be selected. Common tolerance levels are 1%, 0.5%, 0.25%, etc.
High-precision Resistors

In some circuits that require strict control of current or voltage, high-precision resistors must be selected, such as metal film resistors. Higher-precision resistors can ensure that the circuit operates stably under set conditions, avoiding performance fluctuations caused by errors.

Tolerance and Application
Generally speaking, precision instruments and measuring devices require smaller tolerances, while for ordinary power supply circuits or signal processing circuits, resistors with larger tolerances are sufficient.

Temperature Coefficient and Stability
The temperature coefficient (TC) is the proportion by which a resistor changes with temperature, usually expressed in ppm/°C. For applications with significant temperature fluctuations, it is very important to choose resistors with a lower temperature coefficient to ensure the stability of the resistor value under different operating temperatures.

All resistors have a certain resistance value, which represents the degree to which the resistor opposes the flow of electric current.

The unit of resistance is the ohm, represented by the symbol 'Ω'.
An ohm is defined as follows: if a voltage of 1 volt is applied across a resistor and a current of 1 ampere flows through it, the resistance of the resistor is 1 ohm.
In the International System of Units, the unit of resistance is Ω (ohm), and there are also KΩ (kilo-ohm) and MΩ (mega-ohm), where: 1 MΩ = 1000 KΩ, 1 KΩ = 1000 Ω.
The electrical performance indicators of resistors typically include nominal resistance, tolerance, and rated power.
Resistors, together with other components, form functional circuits, such as RC circuits.
