3339P-1-252

Trimmer Potentiometers are adjustable devices used to fine-tune voltage, current, frequency and other electrical settings within electronic circuits. The 3339P-1-252 is a two-terminal, through-hole trimmer potentiometer that provides an adjustable resistance value for use in advanced circuit designs. This device is most commonly used for low-level circuitry in radio and television receiver designs, as well as audio amplifier circuits.

Types

The 3339P-1-252 is a miniature trimmer potentiometer with a single-turn resistance rating of 25 kiloohms. It is a non-rotational trimmer and features a low-profile design for mounting in tight spaces. The device is available in both through-hole and surface mount styles and has a panel or board mount design.

Features

The 3339P-1-252 is a low-profile trimmer potentiometer that features a linear resistance curve across its 25 kiloohm range. It is constructed using a metal multi-turn helical wiper configuration and includes a lockout feature for secure system adjustments. The device features a low thermal coefficient and is designed to operate reliably in temperatures ranging between -65°F and +200°F (-54°C to +93°C).

Applications

The 3339P-1-252 is suitable for use in a wide range of electronic devices, including radio receivers, televisions, amplifiers, audio amplifiers, filters, oscillators, and more. The device can also be used in automatic gain control (AGC) and equalizing circuits, as well as for setting timing and frequency values.

Working Principle

The 3339P-1-252 features a single-turn design that allows for adjustment across its entire 25 kiloohm range. The device is actuated by a metal helical wiper that sweeps the full resistance range when adjusted. The contact force between the wiper and the resistive element is determined by the device\'s lockout feature, which helps to prevent accidental adjustment of the trimmer potentiometer settings.

Conclusion

The 3339P-1-252 is a low-profile, two-terminal trimmer potentiometer with a single-turn resistance rating of 25 kiloohms. It is suitable for use in a wide range of electronic applications, including radio and television receivers, amplifiers, and audio amplifiers, as well as for setting timing and frequency values. The device features a lockout feature to prevent accidental adjustment of the settings and is constructed using a metal helical wiper configuration.
