About Trimmer Resistors - SMD
Sr Passives Trimmer Resistors - SMD
Trimmer resistors are a type of electronic component found in Surface Mount Devices (SMD) that allow for precise adjustment of resistance. They are typically small, rectangular in shape, and have three terminals. The two outer terminals are connected to the circuit, while the middle terminal is used to adjust the resistance.These resistors are useful in a variety of electronic applications, such as circuit tuning, calibration, and temperature compensation. They have a higher level of precision compared to standard through-hole resistors, as their resistance value can be adjusted with a screwdriver or trim tool. This makes them ideal for fine-tuning circuits or compensating for changes in environmental conditions.Trimmer resistors come in various types and sizes, with surface mount versions being more popular due to their small size and ease of assembly. They are commonly used in audio equipment, power supplies, and telecommunication devices. However, they can also be found in a range of other electronic devices that require precise resistance adjustments.
