Resistor Types And Their Characteristics

Apr 01, 2016

Axial lead (Axial Lead) resistor types: axial-lead resistors commonly used types there are three types: synthetic carbon film resistors or carbon film resistors, metal film resistor and wire-wound resistors.

• Carbon film resistors in synthetic carbon film resistor (called carbon resistor) is used for the initial accuracy and temperature stability thought

Ordinary circuits is not important. Typical applications include transistor or FET bias circuit in the collector and the emitter load resistance

Charging capacitor discharge resistor pull-up resistor in digital logic circuit or drop resistance.

Carbon resistor in accordance with logarithm series provides a range of standard resistance value (see table 1), the resistance ranges from 1 ω to 22M to allow

Deviations from the 2% (carbon film resistors) to 5%, or even 20% (synthetic carbon film resistors). Rated power range from 1/8W up to 2W

Power for the 1/4W and 1/2W, 5% and 10% tolerances most resistors.

Like a resistor matrix material, length and cross section than these factors determine resistor attached to the parasitic inductance and stray capacitance, and

Impact on the stability of resistors for high frequency equivalent DC impedance. Thin film resistors are usually has good high-frequency response. 100MHz, can still maintain its accuracy. Carbon resistor can be used 1MHz. Wirewound resistors inductance of high frequency response is the worst. Even non-inductive wire wound resistors (clockwise around the loop is equal to number of coil counterclockwise around the

Due to mismatch process still exists and the residual inductance--translator's note), also has a very high capacitance when operating frequency 50k

Hz above almost unstable.
