Description

 

The 3323V Trimmer is a singe turn cermet trimmer potentiometer designed for precise level adjustments in electronic circuits. With a robust power rating of 0.5W at 70ºC, it ensures stable performance even under challenging conditions. Its linear pins and optimized terminal spacing make it ideal for integration on 2.5 PCBs, while the multi-finger wiper mechanism enhances contact resistance for consistent performance. Offering a wide 220° electrical travel and 250° total mechanical travel, it provides ample adjustment range. Moreover, its cermet resistive element guarantees durability and stability, with a resistance range from 10Ω to 5MΩ and tolerance options of ±10% or ±20%. Despite its small size, it delivers high precision and reliability, making it widely used in circuit protection devices, industrial controllers, and various other fields.
