RC0805FR-071RL

RC0805FR-071RL is an 0805-size surface-mount resettable fuse (PPTC) from the RC0805FR family. It acts as a self-resetting overcurrent protector: under normal current it presents a very low resistance; if the current exceeds its rating, the device heats and its resistance increases sharply to limit current. Once the fault is removed and it cools, it returns to the low-resistance state automatically. The “071” suffix typically indicates a nominal hold current around 0.71 A (with a higher trip current), while “RL” denotes a specific packaging/lead variant. It’s non-polar and suitable for compact boards and reflow soldering. Typical applications include protecting power rails, USB lines, and other low‑power circuits from short circuits or overloads. For exact values (I_hold, I_trip, maximum voltage, resistance, tolerance) and environmental ratings, consult the manufacturer’s datasheet.

RC0805FR-071RL is a low-ohmic, 0805‑size current-sense resistor (≈0.071 Ω). It is used wherever precise low-value current sensing is needed. Typical applications:
- Current sensing in switch‑mode power supplies and DC‑DC converters
- Motor drivers and power management circuits
- Battery management, charging/discharging monitoring
- Overcurrent protection and load‑current measurement in telecom, servers, automotive, and consumer electronics
In short: it serves as a shunt resistor for monitoring, protection, and control in power electronic and automotive/industrial systems.
