Factors to consider between chip resistors and color-coded resistors and sound quality 1

Surface Mount Resistors (SMD) and Through-Hole Resistors (TH) are two commonly used resistor devices that serve functions such as current limiting, voltage dividing, and protection in electronic circuits. For audio equipment, the choice of resistor devices has a significant impact on sound quality. Below are some considerations regarding the relationship between SMD and TH resistors and sound quality:

1. Noise:

- Chip resistors: Chip resistors typically have smaller dimensions and weight, which makes them better able to withstand mechanical and thermal stress, reducing the generation of internal noise. Additionally, the structural design of chip resistors can also reduce noise. Therefore, chip resistors usually provide a lower noise level in audio equipment.diode

- Color ring resistor: The structure of a color ring resistor is relatively large, with numerous internal contacts and solder joints, which may lead to the generation of some current noise and thermal noise. Therefore, compared to chip resistors, color ring resistors may produce higher noise levels to some extent.diode
