Technical Specifications:

The ST-32ETA24 features a resistance value, but the exact value is not specified in the part number itself (further datasheet research would be required to determine the specific resistance value, which is typically 200k-Ohm or 250k-Ohm). The power rating is typically around 0.25W. The operating temperature range is generally between -25°C to +85°C. The temperature coefficient of resistance (TCR) is typically ±100 ppm/°C. It features a through-hole mounting style with a standard pin spacing. The mechanical rotation angle is approximately 210 degrees. The resistance tolerance is usually ±10%. It is constructed with a cermet resistive element to ensure stability and precision. The body is commonly made of a durable plastic material.

Its enclosed construction protects the resistive element from dust, moisture, and other environmental contaminants, ensuring long-term reliability and consistent performance. This makes it suitable for use in industrial, commercial, and consumer electronic applications.
