Trimmer Potentiometers

Trimmer Potentiometers are variable resistors. They are the smallest type of potentiometer, and as such are often used when space is at a premium. A typical application of a trimmer potentiometer is in circuit boards, where they are used to adjust the operational parameters of a circuit, such as the gain of an amplifier.

25SR100LF Application Field and Working Principle

The 25SR100LF is a surface mount, single-turn trimmer potentiometer, with a resistance range of 5-100 ohms. The device is capable of remaining within +/- 5% of its calibrated value over the full life of the product, making it a reliable choice for production applications. The 25SR100LF has a resistance value of 25 SR and a power rating of 0.25 W maximum.

With a stall torque of 0.9 g-cm, this trimmer is suitable for use in high vibration applications. The 10-lead SC-88 package is both RoHS compliant and has a fine-pitch lead spanning of 0.5 mm. As such, it\'s optimised for use with automated placement machines.

Designed with a precision stability of oscillation control, the 25SR100LF is the ideal choice for audio and communication devices. Its fast response time and low noise features also make it an ideal choice for light dimming and display adjustment applications.

The working principle of the 25SR100LF is relatively simple. It has two terminals, one of which is connected to an adjustable sliding contact. The other terminal is connected to the slider. When the slider is adjusted, the resistance value between the two terminals changes accordingly, thereby adjusting the corresponding parameters of the circuit board.

To ensure the best performance of this device, the contact should be cleaned regularly and needs a certain level of force to be applied for adjusting the resistance value. The device is rated for up to 100,000 cycles of adjustment.

In summary, the 25SR100LF is a high precision, stable and reliable trimmer potentiometer, with a resistance range of 5-100 ohms. It is designed for use in audio and communication devices, light dimming and display adjustment applications. The 10-lead SC-88 package makes it optimal for automated placement machines, and the low noise and fast response time of the device ensure the best performance for any application.
