Description

The RUEF090 is a Polymeric Positive Temperature Coefficient (PPTC) resettable fuse by Tyco Raychem designed for overcurrent protection in circuits operating at up to 30V DC. This fuse helps protect sensitive electronic components by increasing resistance under overcurrent conditions and automatically resetting when normal operating conditions are restored. Its radial leaded design ensures ease of integration into circuit designs.

Features

  • Resettable Functionality: Automatically resets after the fault condition is cleared, eliminating the need for replacement.
  • Compact Radial Lead Design: Easy to install with through-hole mounting.
  • High Fault Current Withstand: Handles fault currents up to 40A.
  • Durable Construction: Capable of enduring multiple fault cycles for long-lasting protection.
  • Wide Temperature Range: Operates reliably in a range from -40°C to +85°C.
  • Low Initial Resistance: Ensures minimal power loss during normal operation.

Specifications

  • Type: PPTC Resettable Fuse
  • Voltage Rating: 30V DC
  • Hold Current (I_hold): 900mA (maximum continuous current without tripping)
  • Trip Current (I_trip): 1.8A (current at which the fuse activates)
  • Maximum Current (I_max): 40A (maximum fault current the fuse can safely interrupt)
  • Initial Resistance (Râ‚€): 0.260 ohms (typical)
  • Post-Trip Resistance (Râ‚œ): 0.490 ohms (typical when tripped)
  • Power Dissipation (P_d): 1.5W
  • Operating Temperature Range: -40°C to +85°C
  • Form Factor: Radial leaded for through-hole mounting
  • Time-to-Trip: Fast response depending on current magnitude and ambient temperature.
