Key Features
- 470 kΩ resistance with ±1% tolerance and ±100 ppm/°C TCR in a 0603 package, providing precision voltage-divider and pull-up/pull-down performance in analog and digital circuits
- 0.1 W power rating in a 1.6 mm × 0.8 mm × 0.45 mm package enables high-density SMT placement on 4-layer PCBs with component spacing as tight as 0.1 mm
- RoHS-compliant lead-free (Pb-free) e3 termination finish meets JESD-609 requirements and EU RoHS Directive 2011/65/EU for global market distribution
Applications
The MCR03EZPFX4703 is used in precision voltage dividers, bias networks, and pull-up/pull-down resistor arrays in analog signal conditioning, microcontroller I/O interfaces, and sensor front-end circuits where 470 kΩ ±1% is required in a compact 0603 footprint. Its ±100 ppm/°C TCR ensures resistance drift below 4.7 kΩ across a 100°C operating range, making it suitable for temperature-sensitive ADC reference dividers and comparator threshold networks in industrial instrumentation. The 0.1 W rating handles signal-level currents up to 462 µA at rated voltage, covering most digital pull-up and analog biasing applications in 3.3 V and 5 V systems.

Frequently Asked Questions
What resistance, tolerance, and power rating does the MCR03EZPFX4703 offer in its 0603 package?
The MCR03EZPFX4703 provides 470 kΩ resistance with ±1% tolerance and a 0.1 W power rating in a 0603 (1608M) package measuring 1.6 mm × 0.8 mm × 0.45 mm. At 0.1 W, the maximum continuous voltage across the resistor is approximately 217 V, and the maximum DC current through it at 5 V is 10.6 µA — well within signal-level biasing applications.
How does the ±100 ppm/°C TCR of MCR03EZPFX4703 affect a precision voltage divider in an industrial sensor operating from -40°C to +85°C?
With a ±100 ppm/°C TCR and a 125°C operating range (-40°C to +85°C), the MCR03EZPFX4703 resistance can shift by up to ±1.25% (100 ppm × 125°C), adding up to ±5.875 kΩ of drift to the nominal 470 kΩ. In a resistor-divider ADC reference, this limits uncompensated ratio error to ±0.63% — acceptable for 10-bit ADC accuracy but marginal for 12-bit designs without temperature compensation.
For an MCU GPIO pull-up circuit running at 3.3 V, how much current does the MCR03EZPFX4703 draw when the line is pulled low?
With 3.3 V across 470 kΩ, the pull-up current is 3.3 V ÷ 470,000 Ω = 7.02 µA per pin. This very low current makes MCR03EZPFX4703 ideal for weak pull-ups on I²C SDA/SCL lines where multiple devices share the bus and pull-up current must be minimized to reduce power consumption in battery-operated IoT systems targeting supply currents below 10 µA in standby.
Can MCR03EZPFX4703 be placed on a high-density PCB with 0.1 mm minimum spacing, and does ROHM provide a recommended land pattern?
Yes, the 0603 package (1.6 mm × 0.8 mm body, 0.45 mm height) supports 0.1 mm inter-component spacing on standard 4-layer PCBs with 100 µm trace/space design rules. ROHM's MCR series datasheet specifies a recommended land pattern with 1.5 mm pitch between pad centers and 0.9 mm × 0.9 mm pad size, compliant with IPC-7351 0603 Nominal footprint guidelines.
