The HRU series is an ultra stable flagship primary standard resistor which is an enhanced version of the USR/ASR/CSR series through the use of Bulk Metal® Foil technology. Our HRU Series features an ultra-stable resistive element due to our new generation of stress-free Bulk Metal Foil technology and our proprietary nickel chrome alloy. The resistor is also encapsulated in a specially designed ceramic case, which protects the element against humidity and oxidation. These features deliver an impressive long-term performance of less than 0.2 ppm/year (0.05 ppm/year typical) and an extremely low temperature coefficient of α23 ±0.05 ppm/°C, β ±0.005 ppm/°C 2. This performance is unique to Alpha Electronics throughout the world. Alpha's Bulk Metal Foil construction provides excellent AC characteristics—superior to performance of conventional wirewound standard resistors. The resistive elements are held by special designed case so, it's suitable for environment with vibration during transportation.
