Frequently Asked Questions
What resistance value and tolerance does MCR03EZPFX1201 offer in the 0603 package?
The MCR03EZPFX1201 provides a 1.2 kΩ resistance value with ±1% tolerance in the standard 0603 SMT chip package (1.6 mm × 0.8 mm × 0.45 mm height). This precision tolerance makes it suitable for voltage divider networks and signal conditioning circuits where resistor accuracy directly impacts system performance.
How does the MCR03EZPFX1201 temperature coefficient compare to tighter-spec resistors for automotive sensor circuits?
The MCR03EZPFX1201 has a ±100 ppm/°C temperature coefficient, meaning the 1.2 kΩ resistance shifts by at most ±120 mΩ per degree Celsius. Over an automotive range of -40°C to +125°C (165°C span), total drift is ±1.65%, which meets most automotive biasing requirements at lower cost compared to ±25 ppm/°C thin-film alternatives needed only in precision instrumentation.
Can MCR03EZPFX1201 be used as a current-limiting resistor for 3.3 V GPIO-driven LED indicators?
Yes. At 3.3 V supply with a typical red LED forward voltage of 2.0 V, placing MCR03EZPFX1201 (1.2 kΩ) in series limits current to approximately 1.1 mA — well within the 0.1 W (100 mW) power rating and suitable for low-brightness status LEDs on microcontroller GPIO pins rated to 8 mA to 16 mA drive current.
