SM-43X200

Trimmer Potentiometers

SM-43X200 is a type of trimmer potentiometer designed for a variety of professional and consumer electronic applications.

A trimmer potentiometer is a variable resistor with three terminals. It is typically used for adjusting circuit parameters such as resistance and capacitance. Trimmer potentiometers are usually of either the rotary or vertical slider type. The rotary type features a spindle that rotates on an axle, while the vertical slider type has a metal or plastic contact that can slide up and down.

The SM-43X200 is a rotary trimmer potentiometer. It has a resistance range of 200Ω, and its adjustment range is from 0.5 W to 2.5 W. The current rating of the SM-43X200 is 2.5 mA, and its standard operating voltage is 16V. The SM-43X200 features both a push-on and a screw-on terminal type.

The SM-43X200 is typically used in audio applications, such as the volume controls in headphones or amplifier circuits. It can also be used to adjust the pitch of musical instruments, and as a frequency-setting potentiometer in radio receivers. The SM-43X200 is also useful for precision calibration in electronic test and measurement equipment.

The working principle of a trimmer potentiometer is quite simple. When the user turns the spindle or slides the contact, the resistance between the two outer terminals varies, resulting in a different voltage on either side of the resistor. This voltage can then be used to adjust the operation of the circuit.

In summary, the SM-43X200 trimmer potentiometer is a versatile, adjustable resistor that is perfect for use in a wide variety of applications. Its excellent current and voltage ratings make it ideal for audio, frequency setting, and test and measurement applications.
