- Ultra-tight ±0.05% resistance tolerance on a 20 kΩ value ensures precision accuracy in demanding analog measurement and calibration circuits
- Low ±10 ppm/°C temperature coefficient minimizes resistance drift across temperature extremes, critical for precision signal conditioning
- 0805 surface mount package (2 mm x 1.25 mm) enables automated PCB assembly with standard pick-and-place equipment
- 0.125 W rated power dissipation with metal film construction provides stable, low-noise performance in DC and low-frequency AC circuits
Applications
The ERA6ARW203V is suited for precision voltage dividers, reference networks, and gain-setting resistors in high-accuracy analog front ends for data acquisition, medical instrumentation, and industrial measurement systems. Its ±0.05% tolerance and ±10 ppm/°C TCR ensure that 20 kΩ circuits remain accurate across operating temperature ranges from -55°C to +155°C. Engineers use this resistor in precision ADC input conditioning, bridge sensor circuits, and calibration reference networks where long-term resistance stability directly impacts measurement accuracy.

Frequently Asked Questions
What resistance tolerance and temperature coefficient does the ERA6ARW203V offer for precision analog designs?
The ERA6ARW203V provides a 20 kΩ resistance value with ±0.05% tolerance and a ±10 ppm/°C temperature coefficient. These specifications ensure resistance variation below 2 ohms at room temperature and less than 2 ohms of additional drift per 10°C change, making it suitable for precision reference dividers and gain-setting networks in measurement instruments.
How does the ±10 ppm/°C TCR of the ERA6ARW203V affect performance in a precision voltage divider across -40°C to +85°C?
Over a 125°C span from -40°C to +85°C, a ±10 ppm/°C TCR causes a maximum resistance shift of 1250 ppm (0.125%) from the nominal 20 kΩ value, equivalent to a shift of approximately 25 ohms. In a precision voltage divider, this drift remains within tight bounds compared to standard 100 ppm/°C resistors, which would shift 12.5x more over the same range.
For which precision measurement or medical device circuits is the ERA6ARW203V most commonly specified?
The ERA6ARW203V is commonly used in precision ADC input voltage dividers, Wheatstone bridge circuits for strain gauges and pressure sensors, precision op-amp gain networks, and calibration reference ladders in medical diagnostic equipment and industrial measurement instruments. Its 0.125 W power rating supports signal-level circuits at up to 50 V across the 20 kΩ resistor.
When should engineers choose the ERA6ARW203V over a standard 1% 0805 resistor for a 20 kΩ position?
Engineers should specify the ERA6ARW203V when the 20 kΩ position controls gain accuracy, offset trim, or reference division to better than 0.1%, and when the circuit operates across more than 20°C of temperature variation. Standard 1% resistors with 100 ppm/°C TCR can shift up to 1% from drift alone over 100°C, degrading system accuracy beyond acceptable limits for 16-bit or higher resolution ADC designs.
