RUEF500

Product Category

RUEF500 belongs to the category of resettable fuses, also known as polymeric positive temperature coefficient (PPTC) devices.

Basic Information Overview

  • Use: RUEF500 is used to protect electronic circuits from overcurrent and short-circuit faults.
  • Characteristics: It exhibits a resettable function, allowing it to return to its normal state after the fault is removed. It also offers low resistance in normal operating conditions.
  • Package: RUEF500 is typically available in surface mount packages.
  • Essence: The essence of RUEF500 lies in its ability to provide reliable overcurrent protection while being resettable.
  • Packaging/Quantity: It is commonly packaged in reels or tape and reel packaging, with quantities varying based on manufacturer specifications.

Specifications

  • Voltage Rating: Typically rated for 6V to 60V applications.
  • Current Rating: Commonly available in current ratings ranging from 0.05A to 3A.
  • Operating Temperature: Can operate within a temperature range of -40°C to 85°C.

Detailed Pin Configuration

RUEF500 features a standard two-pin configuration, with one pin connected to the positive terminal and the other to the negative terminal of the circuit.

Functional Features

  • Overcurrent Protection: RUEF500 provides protection by limiting the current flow during overcurrent conditions.
  • Resettable Function: After the fault is removed, RUEF500 resets itself, restoring the circuit to normal operation.

Advantages and Disadvantages

  • Advantages:
    • Resettable functionality increases the lifespan of the device.
    • Provides reliable protection against overcurrent and short-circuit faults.
