2016L150/33DR

Ptc Resettable Fuses Overview

The Littelfuse 2016L150/33DR is a PolySwitch resettable PPTC device in a 2016 surface-mount package. It features a hold current of 1.5A and a trip current of 3A. The component has a maximum power dissipation of 1.4W, a maximum resistance after tripping (R1) of 180mΩ, and an initial resistance (Ri) minimum of 70mΩ. Rated for 15V DC with a maximum fault current of 40A, it operates within a temperature range of -40°C to +85°C.

Ptc Resettable Fuses Feature Summary

• Provides reliable overcurrent protection by raising resistance as it heats to limit current flow during fault conditions.
• Offers automatic circuit restoration without manual replacement once the fault is removed and the device cools down.

Ptc Resettable Fuses Applications

• Overcurrent protection for automotive actuators, screens, and small motors.
• Protection for telephony and networking equipment against high-voltage fault currents.
• Safeguarding rechargeable batteries from short circuits and overcharging via battery strap configurations.

Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix /33DR matches the required tape-and-reel packaging configuration for automated assembly. Confirm the lead-free and halogen-free status aligns with RoHS compliance requirements for your manufacturing process. Ensure the 2016 package dimensions fit the designated footprint on the printed circuit board layout.

Ptc Resettable Fuses Selection Notes

Select this component based on the 1.5A hold current requirement for normal operation and the 3A trip threshold for fault detection. Consider the 15V DC rating and 40A maximum fault current capability relative to the circuit's voltage and surge levels. Evaluate the thermal environment to ensure the -40°C to +85°C operating range and 1.4W power dissipation are sufficient for the application.

Ptc Resettable Fuses Part Context

This part belongs to the PolySwitch resettable PPTC family, designed for solid-state overcurrent protection. These devices function similarly to traditional fuses but offer resettable functionality. The 2016 series provides compact surface-mount solutions suitable for space-constrained designs in consumer electronics, industrial controls, and telecommunications infrastructure.
