Frequently Asked Questions
What resistance value, tolerance, and power rating does the MCR03EZPFX3301 provide?
The MCR03EZPFX3301 provides a resistance of 3.3 kΩ with a ±1% tolerance and a rated power dissipation of 0.1 W (100 mW) at 70°C ambient. Its temperature coefficient of ±100 ppm/°C means the resistance will shift by no more than ±0.33 Ω per 10°C change in temperature, ensuring stable performance across typical operating ranges.
For an LED current-limiting circuit at 3.3 V, how does the MCR03EZPFX3301 perform at typical LED forward voltages?
With a 3.3 V supply and a typical LED forward voltage of 2.0 V, the MCR03EZPFX3301 (3.3 kΩ) limits LED current to approximately (3.3 V - 2.0 V) / 3300 Ω = 0.39 mA, which suits very low-power indicator LEDs. For higher brightness at 5 V with a 2.0 V LED, the same resistor yields about 0.9 mA. If higher currents of 5 mA to 20 mA are needed, a lower resistance value should be selected.
How does the 0603 package size of the MCR03EZPFX3301 compare to 0402 or 0805 resistors for PCB layout planning?
The 0603 package measures 1.6 mm × 0.8 mm × 0.45 mm, occupying roughly 1.28 mm² of PCB pad area. This is approximately twice the size of a 0402 package (1.0 mm × 0.5 mm = 0.5 mm²) and about half the size of an 0805 package (2.0 mm × 1.25 mm = 2.5 mm²). The 0603 size is a practical balance between component density and hand-soldering accessibility during prototype assembly.
Is the MCR03EZPFX3301 RoHS compliant, and can it be used in lead-free manufacturing processes?
Yes, the MCR03EZPFX3301 is lead-free (Pb-free) and RoHS compliant as indicated by its JESD-609 e3 code, meaning it meets the EU RoHS Directive requirements for hazardous substance restrictions. It is rated for lead-free reflow soldering at peak temperatures up to 260°C per IPC/JEDEC J-STD-020, making it fully compatible with modern lead-free solder paste and reflow oven processes.
