Frequently Asked Questions
What resistance, tolerance, and power rating does MCR03EZPFX2002 provide?
MCR03EZPFX2002 provides 20kΩ resistance with ±1% tolerance and 0.1W (100 mW) power rating in a 0603 SMD package. The ±100 ppm/°C temperature coefficient means resistance shifts by no more than 2Ω per 10°C change at room temperature, suitable for stable pull-up and biasing networks.
How does the 0603 package size of MCR03EZPFX2002 compare to 0402 or 0805 resistors for PCB layout?
MCR03EZPFX2002 occupies a 1.6 mm × 0.8 mm footprint in the 0603 case, larger than 0402 (1.0 mm × 0.5 mm) but smaller than 0805 (2.0 mm × 1.25 mm). The 0603 size offers a good balance between hand-soldering accessibility and component density, typically allowing up to 20 resistors per square centimeter on a standard PCB.
For I2C bus pull-up circuits, why is a 20kΩ resistor like MCR03EZPFX2002 sometimes too high a resistance value?
Standard I2C at 400 kHz fast mode requires pull-up resistors between 1kΩ and 4.7kΩ for bus capacitances up to 400 pF. A 20kΩ pull-up slows rise time to above 1 µs, violating I2C timing specs. MCR03EZPFX2002 at 20kΩ is better suited for low-speed I2C at 100 kHz with bus capacitances below 50 pF.
When is MCR03EZPFX2002 a cost-effective alternative to a 0603 precision resistor in voltage divider design?
MCR03EZPFX2002 at ±1% tolerance is a cost-effective choice for voltage dividers where output accuracy of ±2% is acceptable, such as ADC reference scaling circuits operating below 50V. For accuracy requirements below ±0.5%, a ±0.1% precision resistor would be needed, but MCR03EZPFX2002 reduces per-unit cost by up to 70% compared to precision-grade alternatives.
