Definition

A minimal lumped thermal model composed of two thermal resistances and a single thermal capacitance that represents heat transfer through an element or between two environments and one lumped thermal mass; it captures a single dominant time constant and is used for simple transient estimates, controller tuning and first‑order analysis of thermal lag and amplitude attenuation.
