Applications
The MCR03EZPFX2201 is commonly used in pull-up and pull-down resistor networks, voltage dividers, and current-limiting circuits in microcontroller and FPGA-based designs. Its 2.2 kΩ value suits applications in I2C bus pull-up configurations, LED current limiting at 3.3 V or 5 V rails, and sensor interface signal conditioning. The compact 0603 footprint makes it a standard choice for consumer electronics, wearables, and industrial control PCBs.

Frequently Asked Questions
How does the MCR03EZPFX2201 perform as a pull-up resistor in I2C communication circuits?
At 2.2 kΩ, the MCR03EZPFX2201 is suitable for I2C pull-up on buses operating at 3.3 V or 5 V at standard (100 kHz) and fast (400 kHz) modes. A 2.2 kΩ pull-up provides a good balance between drive strength and power consumption, resulting in acceptable rise times while keeping bus current under 2.3 mA at 5 V logic levels.
What is the temperature coefficient of the MCR03EZPFX2201, and how does it affect circuit accuracy over temperature?
The MCR03EZPFX2201 has a ±100 ppm/°C temperature coefficient. Over a 100°C operating range, this produces a resistance shift of approximately ±0.22 Ω — negligible for most signal conditioning and pull-up applications. For designs operating across the full -55°C to +155°C industrial range, the total drift remains within ±2.1%, well within the ±1% initial tolerance for general-purpose use.
Can the MCR03EZPFX2201 be used in LED current-limiting circuits, and what current would it set at 3.3 V?
Yes, with a 3.3 V supply and a forward voltage of approximately 2.0 V for a standard red LED, the MCR03EZPFX2201 would set an LED forward current of roughly 0.59 mA — suitable for low-brightness indicator LEDs or touch-pad backlighting. For higher LED brightness, a lower resistance value in the same 0603 package footprint can replace it without PCB layout changes.
