Product Overview
TEPRO TS 1 Watt, 12.5 Ohm 0.05% Axial Precision Resistor
This axial resistor provides a tightly controlled low ohm/Ω value for analog and instrumentation work that depends on stable, repeatable measurements. Its through-hole format integrates cleanly into calibrated layouts, and a practical soldering tip is to support the leads during heating to maintain alignment. This helps preserve predictable behavior in precision circuits.
