The thermal resistance of the AY33GKE is not explicitly stated in the datasheet, but according to Ohmite's general specifications for their AY series, the thermal resistance is typically around 10-15°C/W.
While the AY33GKE is a wirewound resistor, it's not specifically designed for high-frequency applications. Ohmite recommends their HF series for high-frequency uses. However, the AY33GKE can still be used up to a few hundred kHz, but its performance may degrade above that frequency range.
The AY33GKE is designed to withstand moderate vibration, but it's not specifically rated for high-vibration environments. If you need a resistor for a high-vibration application, consider Ohmite's VSH series, which is designed for such use cases.
The MSL of the AY33GKE is not explicitly stated in the datasheet. However, Ohmite typically rates their resistors as MSL 1, which means they can withstand normal humidity levels without special handling or storage requirements.
The AY33GKE is rated for a maximum operating temperature of 250°C, but it's not recommended for high-temperature soldering processes above 220°C. Exceeding this temperature may damage the resistor or affect its performance.
