1. There are several types of fixed resistors to choose from. The choice of which material and structure of the resistor should be based on the specific requirements of the application circuit. High-frequency circuits should use non-wire wound resistors with distributed inductance and small distributed capacitance, such as carbon film resistors, metal resistors and metal oxide film resistors, thin film resistors, thick film resistors, alloy resistors, and anti-corrosion coatings. Resistors, etc. High-gain small-signal amplifying circuits should use low-noise resistors such as metal film resistors, carbon film resistors, and wirewound resistors. They cannot use synthetic carbon film resistors and organic solid resistors, which are noisy.
The resistance of the selected resistor should be close to a nominal value of the calculated value in the application circuit. The standard series of resistors should be preferred. The resistors used in general circuits allow an error of ±5%~±10%. Precision resistors and resistors used in special circuits should use precision resistors. Resistors with precision of less than 1%, such as 0.01%, 0.1%, and 0.5%, should be used with resistors of these magnitudes. The rated power of the selected resistor must meet the requirements of the resistor power capacity in the application circuit. Generally, the power of the resistor should not be arbitrarily increased or decreased.
If the circuit requires a power type resistor, its rated power can be 1 to 2 times higher than the power required by the actual application circuit. 2, the choice of fuse resistor
Fuse resistors have protective function resistors. Should consider its dual performance when choosing, choose its resistance and power and other parameters according to the specific requirements of the circuit. It is necessary to ensure that it can be quickly blown when overloaded, but also to ensure its long-term stable work under normal conditions. If the resistance is too large or the power is too large, no protection can be achieved.
Three basic principles of resistor selection:
Select high-level resistors that are manufactured using a production line certified by a certification body.
Select resistors that are manufactured by manufacturers with functional advantages, quality advantages, efficiency advantages, functional price advantages, and service advantages.
Select the manufacturer of the upper model catalog that meets the above requirements and order resistors directly from it.
