The thermal resistance of the AW470KE is not explicitly stated in the datasheet. However, according to Ohmite's application notes, the thermal resistance (RθJA) is typically around 10-15°C/W for this series of resistors.
While the AW470KE is a wirewound resistor, it's not ideal for high-frequency applications due to its inductive nature. Ohmite recommends using their non-inductive resistors, such as the RA series, for high-frequency applications.
The AW470KE is designed to handle high-pulse and high-surge applications. Its wirewound construction and ceramic core provide excellent pulse handling capabilities. However, it's essential to ensure that the resistor is properly derated to avoid overheating.
The AW470KE can be mounted in either a vertical or horizontal orientation. However, Ohmite recommends mounting it vertically to ensure proper heat dissipation and to prevent moisture accumulation.
Yes, the AW470KE is RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) compliant, making it suitable for use in environmentally conscious designs.
