Ultra Precision Bulk
Metal Film Resistors
4800 Series
Welwyn Components
BS/CECC approved
Tolerances down to 0.005%
Current noise and distortion below level
of practible measurement
Low thermal e.m.f
Ideal resistor for precision instrumentation
Use of bulk metal gives superior stability
Planar construction gives low residual
capacitance and inductance
