Frequently Asked Questions
What power rating and resistance value does the ERJP14F3901U offer for high-density PCB designs?
The ERJP14F3901U provides a 0.5W power rating with a 3.9kΩ resistance value in a 1210 surface mount package measuring 3.2mm × 1.6mm × 0.6mm, making it suitable for high-density PCB layouts where moderate power dissipation and precise resistance are required.
How does the ±100ppm/°C temperature coefficient of ERJP14F3901U affect circuit stability across industrial temperature ranges?
With a ±100ppm/°C temperature coefficient, the ERJP14F3901U experiences a resistance shift of approximately 100 ppm for every 1°C change in temperature. Over an 80°C industrial operating range (-40°C to +125°C), this results in less than 0.8% total resistance drift, ensuring stable performance in voltage divider and feedback networks under varying thermal conditions.
Which applications are best served by the ERJP14F3901U 3.9kΩ thick film resistor compared to thin film alternatives?
The ERJP14F3901U 3.9kΩ thick film resistor is cost-effective for general-purpose industrial control, consumer electronics, and telecom signal conditioning where ±1% tolerance is sufficient. Thin film alternatives offer tighter tolerances such as ±0.1% and lower TCR around 25ppm/°C, making them preferable only in precision measurement or high-accuracy analog circuits where the additional cost is justified.
Is ERJP14F3901U compliant with RoHS and REACH regulations for use in environmentally restricted markets?
Yes, the ERJP14F3901U carries a Pb-free code of Yes and REACH Compliant status with JESD-609 code e3, confirming it meets RoHS and REACH environmental directives. This makes it fully eligible for use in European, Asian, and North American markets that mandate halogen-free and lead-free components in products shipped after July 2006.
