Description
The 3361 SMD cermet trimmer potentiometer is a versatile and
compact component designed for precise resistance adjustment in
surface-mount applications. This trimmer potentiometer, part of the
SMD trimmer series, is known for its reliability, accuracy, and
ease of integration into electronic circuits. Featuring a 1/4"
square form factor, the 3361 SMD cermet trimmer is suitable for
applications where space-saving is essential. It is designed to be
compatible with SMD manufacturing processes, allowing for efficient
assembly onto PCBs.
Key features of the 3361 SMD cermet trimmer include a durable
cermet element that ensures stable performance over time, even in
harsh environmental conditions. It offers a precise resistance
adjustment capability, typically with a nominal resistance range
from 10Ω to 5MΩ and a tolerance of 10%. This allows for accurate
tuning of voltage dividers, feedback circuits, and other
applications requiring precise resistance values. The trimmer
potentiometer also provides reliable power handling, typically
rated at 0.25W at 70°C, making it suitable for moderate power
applications in various electronic devices. Its temperature
coefficient, usually around ±100 ppm/°C, ensures minimal resistance
variations with temperature changes, maintaining stability in
diverse operating environments.
The 3361 SMD cermet trimmer potentiometer combines compact size,
high reliability, and precise adjustment capabilities, making it an
ideal choice for telecommunications equipment, industrial controls,
consumer electronics, and other applications where accurate
resistance tuning is crucial.
