8G16, 8G24 PRECISION WIRE
WOUND RESISTORS

Download
PDF File

These are high precision wire wound resistors, providing excellent stability over temperature and time.
They use balanced multiple π , low reactance windings employing an exclusive ‘air cushion' technique,
providing virtually stress free elements. They are ‘ non inductively' wound with the direction of winding
reversed at the half turns point. They are suitable for most analogue precision circuits, e.g, gain setting,
bridge balancing, voltage dividing, referencing , etc.
