Key Features
- 82 kΩ resistance in a compact 0603 package (1.6 × 0.8 × 0.45 mm) enables dense PCB layouts in space-constrained consumer and industrial electronics
- 1% (F-grade) tolerance ensures accurate voltage-divider and feedback-network ratios without individual calibration in precision analog signal chains
- REACH-compliant RoHS lead-free thick-film construction rated at 1/10 W meets global environmental regulations and standard SMT reflow profiles
Applications
The MCR03EZPFX8202 is used in voltage-divider networks, pull-up/pull-down resistor arrays, and feedback resistors in op-amp and comparator circuits across consumer electronics, IoT modules, and industrial sensor conditioning boards. The 82 kΩ value is well-suited for high-impedance input biasing and battery voltage monitoring dividers where minimizing quiescent current drain below 1 µA is critical in low-power designs. Its 0603 package integrates seamlessly into automated SMT reflow processes, making it a cost-effective general-purpose precision resistor for high-volume production.

Frequently Asked Questions
In a battery voltage-monitoring divider using MCR03EZPFX8202, how much quiescent current does an 82 kΩ top resistor draw from a 3.6 V Li-ion cell?
With an 82 kΩ top resistor and a similarly high-value bottom resistor (such as 100 kΩ), the total divider resistance is approximately 182 kΩ. At 3.6 V, quiescent current through the divider is about 3.6 V ÷ 182 kΩ ≈ 20 µA — low enough to have negligible impact on a 2000 mAh battery over typical measurement intervals. Designers targeting sub-1 µA sleep-mode draw can switch the divider on only during ADC sampling using an MCU GPIO-controlled enable pin.
How does the 1% tolerance of MCR03EZPFX8202 affect gain accuracy in an inverting op-amp configuration?
In an inverting op-amp with gain = −Rf/Rin, using two 1% tolerance resistors introduces a worst-case gain error of up to ±2% (when Rf is at +1% and Rin is at −1% simultaneously). For an 82 kΩ feedback resistor paired with a 10 kΩ input resistor, the nominal gain is −8.2 V/V, with worst-case error of ±0.16 V/V. This is acceptable for audio amplification, sensor signal conditioning, and ADC input scaling where system gain error budgets are typically 2% to 5%.
Is the MCR03EZPFX8202 suitable for high-frequency RF circuits, or are there better alternatives above 100 MHz?
Thick-film 0603 chip resistors like the MCR03EZPFX8202 exhibit parasitic inductance of approximately 1 nH and parasitic capacitance of around 0.1 pF, which are negligible below 100 MHz. Above 100 MHz the parasitic LC network alters impedance by more than 5%, making them unsuitable for precision RF termination or filter designs in the GHz range. For RF applications from 500 MHz to 6 GHz, designers should select thin-film 0402 or 0201 RF-grade resistors with inductance below 0.3 nH.
