Actual Size
The VISHAY RSK33 resistive dividers are based on a
nickel-chromium thin metal film formulation on an oxidized
silicon substrate and incorporate two resistors of equal
ohmic value for use either as a precision voltage divider or
as a four terminal resistor. The RSK33 micro dividers were
developed as a low cost, temperature and time stable
resistive range for hybrid circuit applications demanding
miniaturization with improved parametric performances in
both industrial and military environments.
Their close ratio tolerance and TCR tracking performances
are particularly relevant to amplifier gain-setting and diverse
attenuator and terminator applications.
