Frequently Asked Questions
What resistance value, tolerance, and temperature coefficient does the ERJ2RKD3403X provide?
The ERJ2RKD3403X offers a 340 kΩ resistance with ±0.5% tolerance and a ±100 ppm/°C temperature coefficient. These specifications make it a precision-grade resistor suitable for applications where accuracy and stability over temperature are critical, such as precision voltage dividers and reference networks operating across industrial temperature ranges.
In which precision analog circuit designs does the ERJ2RKD3403X perform better than standard ±1% resistors?
The ERJ2RKD3403X's ±0.5% tolerance and ±100 ppm/°C TCR outperform standard ±1% resistors in op-amp feedback networks, instrumentation amplifier gain-setting circuits, and 16-bit or higher ADC input conditioning stages. At 340 kΩ, it suits high-impedance signal paths in medical sensors, precision data loggers, and industrial weigh-scale circuits where gain accuracy directly impacts measurement uncertainty.
How does the 0402 package size of the ERJ2RKD3403X affect PCB layout and assembly in dense designs?
The 0402 package measures 1.0 mm × 0.5 mm × 0.35 mm, making it one of the smallest standard SMT resistor footprints and ideal for high-density PCB layouts in portable instruments, wearable electronics, and compact sensor modules. Its small footprint allows placement in tight areas near ICs, minimizing parasitic trace inductance and supporting reflow soldering in automated SMT assembly lines.
What is the power rating of the ERJ2RKD3403X, and how should designers size it for continuous-duty circuits?
The ERJ2RKD3403X is rated at 0.063 W (63 mW) continuous power dissipation. For reliable long-term operation, designers should derate to approximately 50% of this rating, limiting continuous dissipation to around 31 mW, especially in elevated ambient temperature environments above 70°C. At 340 kΩ resistance, the resistor can handle up to about 4.6 V across it at full rated power, suitable for low-voltage precision circuits.
