Frequently Asked Questions
What is the resistance value, tolerance, and temperature coefficient of the MCR03EZPFX1003?
The MCR03EZPFX1003 has a resistance value of 100 kΩ with a ±1% tolerance and a temperature coefficient of ±100 ppm/°C. This combination ensures the resistance stays within ±1% of 100 kΩ at 25°C and drifts no more than ±100 ppm per degree Celsius over the operating temperature range, suitable for precision voltage divider and biasing circuits.
How does the 0603 package size of the MCR03EZPFX1003 affect PCB layout and assembly?
The 0603 package measures 1.6 mm in length, 0.8 mm in width, and 0.45 mm in height, making it one of the more common SMT sizes compatible with standard pick-and-place equipment. Its compact footprint allows high-density placement on PCBs with 0.5 mm pitch pad layouts, and the 0.1 W power rating is adequate for signal-level applications in most embedded and consumer electronics designs.
Is the MCR03EZPFX1003 suitable for medical or industrial applications requiring strict compliance?
Yes, the MCR03EZPFX1003 is RoHS Pb-free compliant and REACH compliant per its JESD-609 Code e3 designation, satisfying regulatory requirements for medical devices, industrial equipment, and products sold in the EU. The ±1% tolerance and ±100 ppm/°C temperature coefficient also meet precision requirements for sensor signal conditioning in medical instrumentation.
What power dissipation limit should be observed when using the MCR03EZPFX1003 in a 5 V circuit?
The MCR03EZPFX1003 is rated at 0.1 W maximum power dissipation. In a 5 V circuit, the maximum continuous current through a 100 kΩ resistor is 50 µA, dissipating 0.25 mW — well within the 0.1 W rating. For a 50 V supply, dissipation would be 25 mW, still safe. Exceeding 0.1 W risks permanent resistance shift or open-circuit failure.
