KOA Speer RF73 Series Fusing Flat Chip Resistors function as resistors under normal conditions and fuse quickly to protect circuits under excessive voltage. These devices share the same shape as the RK73 series and support both flow and reflow soldering methods. The RF73 series includes lead-free terminations compliant with EU RoHS requirements. These components operate within a temperature range from -55°C to +125°C and meet UL1412 safety standards, except for the 0603 (1J) model. The RF73 flat chip resistors are suitable for overcurrent protection in electronic devices.
