Key Features
- 1 MΩ ±1% tolerance thick-film resistor in compact 0603 (1.6 mm x 0.8 mm) SMD package for high-resistance precision divider networks
- Low ±100 ppm/°C temperature coefficient ensuring stable resistance across operating temperature ranges from -55°C to +155°C
- 0.1 W rated power dissipation with RoHS-compliant (JESD-609 e3) construction for use in consumer, industrial, and automotive-adjacent applications
Applications
The MCR03EZPFX1004 is used in high-impedance voltage dividers, bias networks, and pull-up/pull-down circuits where a precise 1 MΩ resistance value is required in a compact 0603 footprint. Its ±1% tolerance supports accurate signal conditioning in sensor interfaces, ADC input protection networks, and low-power leakage measurement circuits. The ±100 ppm/°C TCR keeps resistance drift below 10 kΩ across a 100°C temperature span, maintaining measurement accuracy in thermally varying environments.

Frequently Asked Questions
What resistance, tolerance, and power rating does the MCR03EZPFX1004 provide in its 0603 package?
The MCR03EZPFX1004 provides 1 MΩ resistance with ±1% tolerance and a 0.1 W power rating in a 0603 SMD package measuring 1.6 mm x 0.8 mm x 0.45 mm. The ±1% tolerance ensures that the actual resistance stays within 10 kΩ of the nominal 1 MΩ value, making it suitable for precision voltage dividers and bias networks in analog signal chains.
How does the ±100 ppm/°C temperature coefficient of the MCR03EZPFX1004 affect its use in precision measurement circuits?
A ±100 ppm/°C temperature coefficient means the resistance of the MCR03EZPFX1004 shifts by at most 100 Ω per degree Celsius at 1 MΩ nominal. Over a 50°C operating temperature range, the total drift is less than 5 kΩ (0.5% of nominal), preserving measurement accuracy in ADC input dividers, sensor bias networks, and feedback resistors in op-amp circuits without requiring temperature compensation.
When would a designer choose MCR03EZPFX1004 over a 0402-package 1 MΩ resistor for high-impedance circuit nodes?
The 0603 package of the MCR03EZPFX1004 is preferred over 0402 alternatives when hand-soldering, rework, or optical inspection is required, as the 1.6 mm body length is easier to handle than the 1.0 mm 0402 body. At 1 MΩ, parasitic capacitance on the board traces matters more than package self-capacitance, so the 0603 package does not disadvantage high-impedance nodes compared to 0402 at signal frequencies below 1 MHz.
