Precision Metal Clad Resistor
Easy-to-build High-power & High-precision Resistor
Features
Features
- We accept even a single piece order for any resistance value if it is within the resistance value range.
- The low resistance value is ideal for high-precision current detection. (We recommend a 4-terminal product that suppresses the adverse effects of the terminals)
- Resistive materials used that generate less thermoelectromotive force.
- Excellence in moisture resistance, chemical resistance, withstand voltage and insulation has been realized by complete mold with heat-resistant epoxy resin.
- For your convenience when installing, several options as terminal configuration are selectable.
- The RHF type with improved frequency characteristics is also available. (Ayrton-Perry winding)
