Frequently Asked Questions
What is the power rating and tolerance of the MCR03EZPFX4701, and how does that affect circuit design choices?
The MCR03EZPFX4701 has a 0.1 W power rating and ±1% resistance tolerance with a 4.7 kΩ nominal value. The ±1% tolerance ensures accurate voltage divider ratios in signal conditioning circuits, while the 0.1 W rating is suitable for low-power microcontroller interface signals typically operating at 3.3 V or 5 V rails.
How does the ±100 ppm/°C temperature coefficient of the MCR03EZPFX4701 impact performance over temperature?
At ±100 ppm/°C, the MCR03EZPFX4701 will drift approximately ±10 Ω over a 100°C range from its 4.7 kΩ nominal value, or about ±0.21%. This makes it reliable for general-purpose applications from -55°C to +155°C where tight thermal stability is not critical but consistent performance over typical industrial or consumer temperature ranges is required.
Can the MCR03EZPFX4701 be used as a pull-up resistor for I2C communication lines?
Yes, 4.7 kΩ is the standard recommended pull-up value for I2C buses operating at 100 kHz (standard mode) or 400 kHz (fast mode) with 3.3 V or 5 V logic levels. The 0603 package and SMT mounting make it easy to place close to the bus lines, and the ±1% tolerance ensures consistent bus performance across production units.
