Frequently Asked Questions
What resistance value, tolerance, and power rating does MCR03EZPFX1802 offer for precision circuit design?
MCR03EZPFX1802 provides an 18 kΩ resistance value with a ±1% tolerance and a 0.1 W power rating. Its ±100 ppm/°C temperature coefficient ensures the resistance drifts less than 1.8 Ω per 10°C change, supporting stable voltage divider and biasing circuits.
What are the physical dimensions of MCR03EZPFX1802, and what assembly process does it support?
MCR03EZPFX1802 has a 0603 package body measuring 1.6 mm long, 0.8 mm wide, and 0.45 mm high. It is designed for surface mount technology (SMT) reflow assembly and is RoHS compliant (JESD-609 e3), suitable for automated pick-and-place production in consumer and industrial electronics.
In which circuit positions is MCR03EZPFX1802's 18 kΩ value most useful in microcontroller-based designs?
An 18 kΩ resistor like MCR03EZPFX1802 is commonly used as a pull-up or pull-down on GPIO lines of microcontrollers operating at 3.3 V or 5 V, setting quiescent current below 0.28 mA. It also sets gain in op-amp feedback networks and forms the divider leg in ADC input voltage scaling circuits.
How does MCR03EZPFX1802's ±100 ppm/°C TCR affect measurement accuracy in industrial temperature sensor circuits?
In a voltage divider providing a reference to a temperature sensor ADC input, a ±100 ppm/°C TCR means the 18 kΩ resistance shifts by approximately 1.8 Ω per °C. Over a 50°C ambient range, this equals 90 Ω drift — less than 0.5% of 18 kΩ — keeping measurement error well within the ±1% initial tolerance for most industrial sensor applications.
