What are the 5G10 Series Mini-Ohm Precision Wire Wound Resistors?
The 5G10 is a precision wire wound resistor in the Mini-Ohm axial leaded series, engineered to deliver ultra-high resistance accuracy and exceptional long-term stability across temperature and time. Built on a wire wound construction using the highest-quality copper alloy drawn from melts of known resistivity and tightly controlled temperature coefficients, the 5G10 is designed for applications where even a fraction of a percent of resistance drift is unacceptable. With tolerances as tight as ±0.01% and a temperature coefficient of resistance (TCR) of 3 ppm/°C, the 5G10 occupies the highest-accuracy tier within RARA Electronics’ precision resistor portfolio, alongside the 8G16/8G24 and GG102 wire wound series.
A defining feature of the 5G10 is its balanced multiple-π winding configuration, which minimises self-inductance and keeps reactive impedance negligible across DC and low-frequency precision circuits. This makes the series suitable for measurement and feedback applications where wirewound types are sometimes avoided due to their inductive character — the 5G10’s winding geometry ensures that inductance does not introduce impedance error in sensitive signal conditioning circuits. The result is excellent noise levels alongside the tightest achievable initial calibration accuracy.
The resistance range spans 10Ω to 200kΩ, with custom values available to order with a minimum quantity of ten pieces for non-standard parts. The 5G10 is offered in multiple body variants, with the 5G10D model rated to the full 0.2W power dissipation. Operating temperature range extends from −55°C to +160°C, and all leads are tinned copper to ensure compatibility with standard PCB soldering processes. RARA Electronics holds ISO 9001 and IATF 16949 certifications, and the 5G10 is manufactured to the same quality standards relied upon by major industrial and instrumentation customers globally, including Toshiba, Siemens, Rockwell, LG, and Schneider Electric.
As a precision wire wound type, the 5G10 is distinguished from metal film and thin film chip alternatives by its superior long-term stability under load. RARA precision wire wound resistors are engineered for extended load life — maintaining resistance values within specification across thousands of hours of continuous operation, not merely at the point of initial measurement. This makes the 5G10 the preferred choice wherever precision circuit performance must be sustained over a prolonged service life rather than simply verified at incoming inspection.

Applications of the 5G10 Series Mini-Ohm Precision Wire Wound Resistors
Where RARA precision resistors are deployed in the field.
Calibration laboratories and metrology equipment — reference resistance standards and secondary resistance standards requiring traceability to national measurement institutes
Test and measurement instrumentation — precision bridges, resistance decade boxes, LCR meters, and parameter analysers where initial accuracy and long-term drift both determine instrument performance
Current and voltage measurement circuits — shunt resistor networks, Wheatstone bridge arms, voltage dividers, and instrumentation amplifier input networks where a 0.01% resistance error translates directly into a 0.01% measurement error
Feedback and control networks — op-amp feedback resistors, DAC output scaling networks, ADC reference dividers, and PID controller gain-setting resistors where low TCR prevents gain error and offset drift across operating temperature
Medical instrumentation — patient monitoring equipment, infusion pumps, diagnostic analysers, and imaging systems requiring high-accuracy signal conditioning where resistance tolerance directly affects clinical measurement accuracy
Defence and aerospace electronics — avionics, guidance systems, and mission-critical control circuits demanding resistors that maintain specification across wide temperature ranges from −55°C to +125°C
Industrial automation and process control — precision signal conditioning, sensor interface circuits, and transmitter networks where stable resistance values are required over extended field service lifetimes
Power supply feedback and sensing — output voltage setting networks and regulation feedback dividers in laboratory and bench power supplies where accuracy and stability are primary specifications
