  • Package: Radial Lead Form
  • Essence: Protects circuits from overcurrent events by increasing resistance when the current exceeds the threshold.
  • Packaging/Quantity: Available in reels or bulk packaging, quantity varies based on supplier.

Specifications

  • Voltage Rating: 60V
  • Hold Current: 0.20A
  • Trip Current: 0.40A
  • Maximum Current: 3.00A
  • Operating Temperature Range: -40°C to 85°C
  • Resistance: <0.5Ω (Initial), >10Ω (Trip)

Detailed Pin Configuration

The RXEF020S-2 features a radial lead form with two leads for easy integration into circuit designs. The pin configuration includes a clear indication of the polarity for proper installation.

Functional Features

  • Resettable: Automatically resets once the fault condition is removed.
  • Polymeric Material: Provides durability and reliability in various operating conditions.
  • Positive Temperature Coefficient: Exhibits an increase in resistance with temperature rise, effectively limiting current flow during overcurrent events.

Advantages and Disadvantages

Advantages

  • Resettable functionality increases product lifespan.
  • Polymeric material enhances durability.
  • Positive temperature coefficient offers self-regulating protection.

Disadvantages

  • Limited maximum current handling compared to some non-resettable alternatives.
  • Initial cost may be higher than traditional fuses.

Working Principles

When the current flowing through the RXEF020S-2 exceeds the trip current, the device's resistance rapidly increases, limiting the current flow and protecting the circuit. Once the fault condition is removed, the PPTC device resets, allowing normal operation to resume.

Detailed Application Field Plans

The RXEF020S-2 is suitable for a wide range of applications, including: - Consumer Electronics - Automotive Electronics - Industrial Control Systems - Telecommunications Equipment - Power Supplies

Detailed and Complete Alternative Models

  • RXEF010S-2: Lower hold and trip currents for more sensitive protection.
  • RXEF030S-2: Higher hold and trip currents for increased current handling capacity.
  • RXEF050S-2: Enhanced current handling capability for heavy-duty applications.

In conclusion, the RXEF020S-2 offers reliable overcurrent protection with its resettable PPTC design, making it a valuable component in various electronic systems.
