Overview
The ROHM MCR-18 EZH JW 180 E is a general-purpose thick film chip resistor offering 180-ohm nominal resistance with ±5% tolerance (J-grade). This surface-mount component uses metal-glaze technology to ensure stable performance across temperature extremes. The MCR-18 EZH series ships on paper tape (4mm pitch) wound on 180mm reels, making it ideal for high-volume assembly and automated pick-and-place operations.
Key Features
