Frequently Asked Questions
How does the ±100 ppm/°C TCR of MCR03EZPFX1801 affect circuit performance across temperature extremes?
The MCR03EZPFX1801's temperature coefficient of resistance (TCR) of ±100 ppm/°C means the 1.8 kΩ nominal value drifts by no more than 180 Ω per 1000°C change, or approximately 18 Ω across a 100°C operating range from -55°C to +155°C. This low drift makes it suitable for precision analog divider networks and sensor bias circuits that must maintain better than 1% accuracy across automotive and industrial temperature ranges.
What power dissipation can the MCR03EZPFX1801 handle in a typical PCB application?
The MCR03EZPFX1801 is rated at 0.1 W (100 mW) maximum continuous power dissipation in an 0603 package measuring 1.6 mm x 0.8 mm x 0.45 mm. At 1.8 kΩ, this corresponds to a maximum continuous current of approximately 7.45 mA or a maximum voltage of approximately 13.4 V across the resistor, providing comfortable headroom for most 3.3 V and 5 V logic circuit applications.
For which PCB assembly processes is the MCR03EZPFX1801 best suited given its 0603 form factor?
The MCR03EZPFX1801's 0603 SMT package (1.6 mm x 0.8 mm, 0.45 mm height) is compatible with standard reflow soldering at peak temperatures up to 260°C per IPC/JEDEC J-STD-020, as well as automated pick-and-place at placement rates exceeding 20,000 components per hour. Tape-and-reel packaging is available for reel diameters of 178 mm or 330 mm, supporting both low-volume prototyping and high-volume production runs in consumer and industrial electronics.
How does MCR03EZPFX1801 compare to a 0402 package resistor of the same value for high-density board designs?
Compared to a 0402 resistor of the same 1.8 kΩ, ±1% value, the MCR03EZPFX1801 in 0603 offers a larger pad footprint of 1.6 mm x 0.8 mm, making it more suitable for hand-soldering during prototyping and reducing placement sensitivity to ±0.2 mm misalignment. The 0603 also handles up to 0.1 W versus approximately 0.063 W for the 0402 format, providing greater thermal margin in current-limiting and pull-up applications in 5 V circuits.
