What are the key features of MCR03EZPFX2701?
- 2.7 kΩ resistance with 1% tolerance (F-grade) and ±100 ppm/°C TCR for stable resistance in precision signal-conditioning and feedback networks
- 0.1 W power rating in compact 0603 (1.6 mm x 0.8 mm) footprint supports current-limiting, pull-up, and voltage-divider functions on crowded PCBs
- Thick-film rectangular construction in ultra-low 0.45 mm profile enables placement on thin rigid-flex and multilayer PCBs with tight Z-axis clearances
- RoHS compliant (Pb-free, JESD-609 e3) and REACH compliant for seamless export to EU, China RoHS, and other regulated electronics markets
- MCR series wide availability in standard E96 values with a 9-year estimated shelf life (YTEOL) reduces long-term supply continuity risk for production programs
What is MCR03EZPFX2701 used for?
The MCR03EZPFX2701 is used in signal-conditioning circuits, I2C/SPI bus pull-up networks, and feedback dividers in low-power microcontroller and sensor interface designs where a 2.7 kΩ value at 1% accuracy is required on a compact 0603 footprint. Its ±100 ppm/°C temperature coefficient suits automotive and industrial sensor boards operating from -40°C to +125°C where resistance drift must remain below 1% over the full temperature range. The 0.1 W rating handles typical pull-up and current-limiting duties on 3.3 V and 5 V signal rails without thermal derating.

Frequently Asked Questions
What resistance, tolerance, and TCR does MCR03EZPFX2701 provide, and how do these specs perform in a precision voltage divider?
The MCR03EZPFX2701 has 2.7 kΩ resistance with ±1% tolerance and ±100 ppm/°C temperature coefficient. In a voltage divider from a 3.3 V rail, two 2.7 kΩ resistors at 1% tolerance produce a midpoint voltage accurate to within ±33 mV, and the ±100 ppm/°C TCR ensures the ratio drifts by no more than 0.1% over an 100°C temperature span, keeping ADC reference errors below 1 LSB in 10-bit converter designs.
For a 3.3 V I2C pull-up network, how much current does MCR03EZPFX2701 draw and does it stay within its 0.1 W power rating?
With a 3.3 V supply and 2.7 kΩ pull-up resistance, static pull-up current is 3.3 V / 2700 Ω = 1.22 mA per line, dissipating 3.3 V × 1.22 mA = approximately 4 mW per resistor. This is well within the 0.1 W (100 mW) power rating of MCR03EZPFX2701, leaving a safety margin of over 95%, so even three I2C pull-up resistors of this value on the same PCB do not approach thermal limits under normal operating conditions.
What are the physical dimensions of MCR03EZPFX2701, and can it be used on rigid-flex or thin HDI PCBs?
MCR03EZPFX2701 measures 1.6 mm length, 0.8 mm width, and 0.45 mm height, conforming exactly to the IEC 0603 SMD footprint standard. Its 0.45 mm low-profile body is compatible with rigid-flex PCBs and high-density interconnect (HDI) boards where component height above 0.6 mm causes interference with adjacent layers or overlapping flex folds, making it a suitable choice for wearable electronics, thin IoT modules, and medical patch devices requiring a total PCB assembly height under 1 mm.
How does the ±100 ppm/°C TCR of MCR03EZPFX2701 limit resistance drift in automotive sensor applications across -40°C to +125°C?
Over the automotive temperature range of -40°C to +125°C, which spans 165°C, a TCR of ±100 ppm/°C results in a maximum resistance change of 100 ppm × 165 = 16,500 ppm, or ±1.65% from the nominal 2.7 kΩ value. Combined with the initial 1% tolerance, the worst-case total resistance deviation is approximately ±2.65%, which keeps threshold voltages in comparator and ADC input dividers within the ±3% accuracy budget typical of automotive temperature sensing circuits.
Is MCR03EZPFX2701 available in tape-and-reel format for high-volume SMT production, and what is its estimated shelf life?
Yes, MCR03EZPFX2701 ships in tape-and-reel format on standard 8 mm carrier tape compatible with high-speed pick-and-place machines placing 0402 to 1206 components. ROHM estimates a component shelf life (YTEOL) of approximately 9 years from date of manufacture when stored at 25°C and 60% relative humidity in sealed moisture-barrier bags with desiccant, making it suitable for buffer stock programs and long-lifecycle industrial and automotive production programs requiring predictable component availability.
