Additional Details:

The ST-32 series typically features a cermet resistive element, known for its excellent stability and low temperature coefficient. The enclosed construction protects the element from dust, moisture, and other environmental factors, ensuring reliable operation. The specified 200 ohm resistance makes it ideal for applications requiring a relatively low impedance. The 'ETA' designation likely relates to the lead configuration and mounting style, designed for ease of integration into circuit boards. The (22) likely refers to a specific manufacturing or production code. The power rating is typically low, around 0.25W or less, so care should be taken not to exceed this limit.
