Isabellenhütte AZ-H1 Series

Isabellenhütte AZ-H1 Series
The AZ-H1 through-hole resistor series from Isabellenhütte offers 4-terminal connection technology for current sensing applications with very low TCR. Designed for easy heat sink mounting, the Kelvin connections on this resistor allow high precision measurements even with low resistance range of 0.002Ω to 1Ω. The AZ-H1 series from Isabellenhütte has low inductance and has high pulse power handling capabilities.
