ST5TP104

Trimmer Potentiometers are used to control the resistance of a circuit. The ST5TP104 is a four-gang trimmer potentiometer featuring an exposed terminal arrangement similar to that of trimmer potentiometers on surface mount packages. Generally, trimmer potentiometers are resilient and versatile with moderate stability over temperature and frequency.

The ST5TP104 has a large number of applications in various fields such as medical diagnosis systems, audio and video equipment, communications equipment, and automotive electronics. It is primarily used to adjust the relative resistance between two circuit terminals so as to optimize the performance of the target circuitry by adjusting the voltage drop or the current flow across a certain connection.

The ST5TP104 features an effective linear track taper that provides reliable results over a temperature range from -40 to +85°C. It has an adjustable resistance range of 50 to 400 Ω and a power rating capability from 0.1W up to 0.3W. The device is also able to support up to four adjustable resistance elements per package.

Working Principle

The ST5TP104 operates on the principle of having two terminal elements on the total resistance from an external circuit connection. The total resistance is adjustable by altering the terminal elements’ position along the length of the track. By creating an electrical connection between the two ends of the terminal element, it is possible to adjust the resistance of the entire circuit.

The adjustable terminal elements are located in the center of the track and each element is connected to the total resistance. As the terminal elements are moved along the total resistance track, the entire resistance of the circuit is adjusted.

In addition to the adjustable terminal elements, the ST5TP104 also features a track-type contact system which greatly improves the stability of the device, especially when operated at lower resistances. This contact system enhances the device’s lifespan and maintains a consistent level of performance over a wide temperature and frequency range.

Conclusion

In conclusion, the ST5TP104 is an excellent trimmer potentiometer that is suitable for various applications in the fields of medical diagnosis systems, audio and video equipment, communications equipment, and automotive electronics. Its effective linear track taper provides the user with reliable results when adjusting the resistance of a circuit. The device is highly stable over temperature and frequency with an adjustable resistance range of 50 to 400 Ω and power rating capability from 0.1W up to 0.3W.
