Description:
The 3296S cermet trimmer stands out as a meticulously designed component that blends robustness with precision tuning capabilities. Its core is made from a cermet element, known for its reliability and stability across a range of environmental conditions. This trimmer is presented in a 3/8” square configuration, making it compact yet versatile for a multitude of applications. The integration of multi-turn functionality allows for fine-tuned adjustments, enclosed in a fully sealed body to ensure longevity and resistance against environmental challenges.
Adopting a side adjustment style, the 3296S allows for straightforward alterations even when space is at a premium, providing ease of use in dense circuit designs. For mounting, it employs a through-hole method, ensuring a secure and durable connection to the circuit board. It offers excellent performance with a rated power of 0.5W at 70℃, suitable for various electronic applications.
One of its noteworthy attributes is the broad resistance range it covers, from 10 ohms to 5 Megohms, with a tolerance of 10%. This wide range makes it adaptable to numerous resistance requirements in electronic circuits. Moreover, it exhibits low contact resistance variation (CRV), which is less than or equal to 3% of the resistance value or 3 ohms, highlighting its precision and reliability in maintaining the desired resistance setting.
The trimmer is designed to operate within a temperature range of -55°C to +125°C, further emphasizing its suitability for use in a wide array of operating conditions. Furthermore, users will appreciate the finely tuned control it offers, with 25 turns of adjustment travel and a total mechanical travel of 30 turns, facilitating exact resistance settings for intricate electronic tasks.
Such design considerations ensure that the 3296S cermet trimmer is not just a component but a reliable and precise tool for tuning and maintaining the performance of electronic circuits across a broad spectrum of applications.
