Frequently Asked Questions
What tolerance and temperature coefficient does the ROHM MCR03EZPFX3300 maintain across its operating range?
The MCR03EZPFX3300 specifies ±1% resistance tolerance and a ±100 ppm/°C temperature coefficient, meaning resistance shifts less than 2.1% across the full -55 °C to +155 °C operating span, making it suitable for precision analog and feedback networks.
How does the 0603 package of the MCR03EZPFX3300 compare to 0402 alternatives for hand-soldering rework?
The 0603 footprint (1.6 × 0.8 mm) of the MCR03EZPFX3300 is approximately 2.5 times larger in pad area than an 0402 component, making it significantly easier to rework manually with a soldering iron while still supporting automated pick-and-place at high production volumes.
At what LED forward current is the MCR03EZPFX3300 typically used as a current-limiting resistor on a 3.3 V supply?
With a 3.3 V supply and a typical LED forward voltage of 2.0 V, the MCR03EZPFX3300 at 330 Ω limits forward current to approximately 3.9 mA, which is within the safe operating range for low-power indicator LEDs rated at 5 mA to 10 mA.
