Frequently Asked Questions
What is the resistance value and tolerance of the MCR03EZPFX3001, and how precise is it for analog circuits?
The MCR03EZPFX3001 has a resistance of 3 kΩ with a ±1% tolerance, placing it in the precision thick film resistor category. The ±1% tolerance limits the worst-case resistance to a range of 2.97 kΩ to 3.03 kΩ, which is accurate enough for feedback dividers in op-amp circuits, voltage references, and I2C pull-up networks in 3.3 V and 5 V systems.
What power rating and temperature coefficient does the MCR03EZPFX3001 offer in a 0603 package?
The MCR03EZPFX3001 is rated at 0.1 W (100 mW) with a temperature coefficient of ±100 ppm/°C. At a resistance of 3 kΩ, this 0.1 W rating allows a continuous DC current of approximately 5.8 mA. The ±100 ppm/°C TCR means that over a 100°C operating temperature range, the resistance drifts by no more than ±1%, suitable for general-purpose precision resistor applications.
What are the physical dimensions of the MCR03EZPFX3001 and how does it fit on a 0603 PCB footprint?
The MCR03EZPFX3001 measures 1.6 mm in length and 0.45 mm in package height, following the standard 0603 SMT resistor case size. The 0603 footprint uses two rectangular solder pads on the PCB, and at 1.6 mm length it is smaller than the 0805 case, enabling finer component density on multilayer PCBs in smartphones, wearables, and compact industrial modules.
When should the MCR03EZPFX3001 be chosen over a 1% 0805-case resistor of the same value?
The MCR03EZPFX3001 0603 case is preferable to a 0805 alternative when board area is limited and the 0.1 W power rating is sufficient. A 0805 resistor occupies roughly 2 mm x 1.25 mm compared to the MCR03EZPFX3001's 1.6 mm x 0.8 mm body, so switching to 0603 can recover over 30% of the pad area per resistor site — important in high-density analog boards with dozens of 3 kΩ pull-up resistors.
