High Frequency Resistors - RY31A

High Frequency Resistors - RY31A

frequency resistors


Oxide Film - RY31A, with the inner and outer surfaces coated with a special glass, features higher thermal resistance and larger electric power capacity for the compact volume. Unlike conventional wire wound type, the volumetric resistance will provide superior stability versus frequency and excellent durability against transient voltage. RY31A can be suitable for the application with large current as well as high frequency circuit.
