A chip resistor also known as surface-mount device or SMD resistor is an integrated circuit (IC) device designed in square or rectangular chip bundles. A resistor is a passive component and can only decrease current signals.
Chip resistors use different technologies each with substantial merits and detriments. Some of the widely used technologies in chip resistors are as follows:
1. Thin film technology:
This technology depends on the deposition on a thin metallic layer on a ceramic substrate. Resistors build using this technology possess enhanced resistance for a given area, and thus this type of resistors are reasonable and save a lot of space. However, in this type of resistors, the film is susceptible to failure owing to high temperatures, chemical contamination, and water vapor.
2. Thick film resistors:
This type of resistors are formed by applying a resistive metallic paste on the base. They offer improved resistance per given area and are cost-efficient as compared to other types of resistors, for instance: wirewound resistors. Their frequency is similar to foil and thin film resistors. However they are comparatively noisier than other types. Notwithstanding their disadvantages, they are extensively used in circuit units that need less accuracy and permanency.
3. Foil resistors:
This type of resistors are formed by applying a metal foil to a ceramic substrate which is photo-etched with a resistive design. This procedure develops a resistor with the advantageous features such as improved stability, reduced capacitance, non-inductance, and reduced noise without forgoing speed and precision. Hence, they are widely in demand from various electronics industries.
