Frequently Asked Questions
What are the resistance, tolerance, and power rating of the ERJ8ENF3902V?
The ERJ8ENF3902V is a 39 kΩ thick-film resistor with 1% tolerance and a 0.25 W power rating. These specifications make it suitable for precision signal conditioning, voltage divider networks, and feedback resistor positions in analog circuits where accuracy within 1% of the nominal value is required.
Why choose the 1206 package size for the ERJ8ENF3902V in a PCB design?
The 1206 package (3.2 mm × 1.6 mm × 0.6 mm height) offers a balance between compact SMD footprint and ease of automated assembly, handling up to 0.25 W without a heatsink. Compared to 0402 or 0603 packages, the 1206 provides better power handling and is more tolerant of placement tolerances in high-volume production environments.
In which precision analog applications is the ERJ8ENF3902V commonly used?
This 39 kΩ 1% resistor is commonly used in op-amp gain-setting networks, ADC input voltage dividers, sensor interface conditioning circuits, and power supply feedback dividers where the 1% tolerance ensures predictable gain and voltage ratios. Industrial measurement equipment, medical devices, and precision test instruments frequently specify this Panasonic ERJ series resistor.
What does the thick-film construction of ERJ8ENF3902V mean for noise and stability performance?
Thick-film resistors like the ERJ8ENF3902V exhibit low current noise levels and a typical temperature coefficient in the range of ±100 ppm/°C, providing stable 39 kΩ resistance across operating temperature ranges. While not as low-noise as thin-film alternatives, the thick-film construction offers cost-effective precision at 1% tolerance suitable for most analog signal chain designs.
