New Generation Stress-Free BulkMetal® Ultra-Stable Resistor Element Utilizing Bulk Metal Foil Technology and Proprietary Nickel-Chromium Alloy
Alpha Electronics has been providing stable performance for many years. The HRU series features ultra-stable resistive elements that utilize next-generation stress-free Bulk Metal® foil technology and a unique nickel-chromium alloy. The resistive elements are encapsulated in a specially designed ceramic case to protect against humidity and oxidation. These features achieve exceptional stability of 0.2ppm/year (actual value: 0.05ppm/year) and extremely low temperature characteristics of α23̟±0.05ppm/℃ and β±0.005ppm/℃². 【Features】 ■ Outstanding long-term stability: Achieves ≦0.2ppm/year (actual value: ≦0.05ppm/year) ■ Outstanding temperature characteristics: Achieves ≦α23±0.05ppm/℃ and β±0.005ppm/℃² ■ Outstanding humidity characteristics: Achieves ≦0.1ppm/%RH ■ Outstanding atmospheric pressure characteristics: Achieves ≦0.001ppm/hPα ■ Resistance value range: 10Ω, 100Ω (1Ω and 1kΩ are scheduled for release in 2019) ■ Can be used in air without the need for expensive and maintenance-intensive oil baths, approximately 240g (0.52lbs)
