Störfestigkeitswerte

Störfestigkeitswerte, often translated as immunity levels or disturbance resistance values, are crucial metrics used to quantify the ability of an electronic device or system to withstand unwanted electromagnetic interference. These values indicate the maximum level of external electromagnetic disturbances that a device can tolerate without exhibiting degraded performance or malfunctioning. Typically, Störfestigkeitswerte are determined through standardized testing procedures that expose the device to various types of interference, such as conducted disturbances (e.g., voltage dips, surges, radio frequency conducted disturbances) and radiated disturbances (e.g., electromagnetic fields).

The specific Störfestigkeitswerte for a device are usually expressed in decibels (dB) or volts (V) and are often presented in datasheets or technical specifications. Higher Störfestigkeitswerte signify greater immunity to electromagnetic interference. These values are essential for ensuring the reliability and proper operation of electronic equipment, particularly in environments where electromagnetic pollution is prevalent, such as industrial settings, medical facilities, or automotive applications. Compliance with relevant electromagnetic compatibility (EMC) standards often requires devices to meet specific Störfestigkeitswerte.
