Ultra-precision metal foil resistor *Achieves a resistance temperature characteristic of ±0.05 ppm/℃!
Achieves an excellent long-term stability of 5 ppm/year! Adopted in various applications where high precision, stability, and reliability are required, such as high-precision industrial equipment.
Alpha Electronics' "Metal Foil Precision Resistors" are ultra-precision resistors that use a special alloy foil with a thickness of several micrometers for the resistance element, unlike conventional precision-grade metal film resistors or wire-wound resistors. Regarding the important performance of long-term stability, unlike metal film resistors which use thin films, the use of several micrometers of metal foil allows for the extraction of the stable properties inherent to metals, resulting in products with very small aging changes. The minimum temperature coefficient of resistance is 0.05 ppm/°C (typical value), and the minimum resistance value tolerance is ±0.0025%, with an aging change of approximately 5 ppm/year* making it an excellent product in terms of long-term stability. (*For hermetic types) They are used in high-precision electronic devices, electronic measuring instruments, and precision detection circuit designs for high-precision amplification circuits and reference power supplies in medical devices. 【Product Lineup Features】 ■ Temperature coefficient of resistance: ±0.05 ppm/°C (typical value from 0°C to +60°C) ■ Resistance value tolerance: ±0.0025% ■ Aging change: 25 ppm/year, 50 ppm/3 years (Hermetic type 5 ppm/year, 10 ppm/3 years) ★ We will be exhibiting at Techno Frontier 2019: Power Supply System Exhibition ★ Booth: No.6B-35
