Ultra Precision Bulk

Metal Film Resistors

Welwyn Components

4800 Series

• 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

•
