0603L200SL-VYR

Overview

The Littelfuse 0603L200SL-VYR is a surface-mount PolySwitch resettable PPTC device designed for overcurrent protection in compact electronic circuits. It operates within a hold current range of 200mA and a trip current of 400mA, with a maximum voltage rating of 6V. The component features a low resistance profile to minimize power loss during normal operation. It is housed in a standard 0603 package, enabling automated assembly on printed circuit boards. The device provides reliable protection against short circuits and excessive current loads without requiring replacement after tripping.

Feature Summary

• Provides automatic resettable overcurrent protection for sensitive circuit components
• Features low resistance construction to maintain signal integrity and efficiency
• Designed for surface-mount assembly compatible with standard reflow soldering processes

Applications

• Portable consumer electronics such as mobile phones and tablets

Procurement Notes

Verify the specific suffix VYR corresponds to the required tape and reel packaging configuration for your manufacturing line. Confirm that the 6V rating aligns with your system's maximum operating voltage. Ensure the 0603 footprint matches your PCB design constraints. Check for RoHS compliance documentation if required by your regional regulations.

Selection Notes

Select this component when space constraints necessitate a surface-mount form factor. Choose based on the 200mA hold current requirement for your specific load. Consider the 6V maximum voltage limit for low-voltage applications. Evaluate the thermal environment to ensure the device can dissipate heat effectively during fault conditions without affecting nearby components.
