MELF Type Fixed Metal Film Resistors (RN41/RM41)
The RN41 and RM41 series are MELF (Metal Film) fixed resistors designed for surface mounting. Their cylindrical shape eliminates mounting directionality, making them versatile for various applications. These resistors offer high precision, excellent noise characteristics, and robust electrode strength. They are compatible with reflow, flow, and iron soldering processes and meet EU-RoHS requirements. Select models are AEC-Q200 qualified, making them suitable for demanding environments.
