A metal film pattern forms a ladder network with high resistance branches paralleling low resistance branches. A cut through the low resistance branch inserts the parallel high resistance into the circuit. The resistance portions are in a binary sequence so that the resistor can be adjusted to close precision over a wide resistance range. The ladder pattern is folded into a compact area.
