High Voltage Resistors
High Frequency Resistors - RY31A / 氧化膜高频电阻
Oxide Film - RY31A Resistors, with the inner and outer surfaces coated with
a special glass,features higher thermal resistance and larger electric power
capacity for pact 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.
