The Walter MSH2512 series alloy resistor sampling pure metal plate process has high strength, corrosion resistance, pulse resistance, and high reliability. The MSH series uses two alloy materials: 0.5mR~3mR uses manganese copper composite alloy, and 4mR~56MR uses iron chromium aluminum composite alloy. Manganese copper composite alloy has high reliability and ultra-low resistance characteristics, and iron chromium aluminum composite alloy has ultra-low temperature drift characteristics, both of which are composite gold materials with high reliability for alloy resistors. The MSH2512 series has 2 power options, 2W and 3W.
