This document describes the features and characteristics of PTC thermistors, which are primarily used for temperature protection. They have well-defined protection temperature levels, very fast reaction time, accurate resistance for ease of circuit design, excellent long term behavior, and a wide range of protection temperatures.
This document provides technical specifications and ordering information for the Vishay BCcomponents 2322 series of Positive Temperature Coefficient (PTC) thermistors. These devices are designed primarily for sensing and thermal protection applications, such as motor protection and liquid-level indication.
The datasheet details electrical characteristics including maximum resistance at 25 °C, minimum resistance thresholds, and a maximum DC voltage rating of 30 V. It includes a comprehensive table correlating nominal working temperatures with specific catalog numbers (e.g., 91072 to 91087) and physical dimensions for various leaded and naked chip configurations.
