0ZCK0050AF2E

Ptc Resettable Fuses Overview

The Bel Fuse 0ZCK0050AF2E is a surface-mount PPTC resettable fuse in the 0ZCK series. It features a 500 mA hold current and a 1 A trip current, rated for a maximum voltage of 9 VDC. The device exhibits an initial resistance of 850 Ohms and operates within a temperature range of -40°C to +85°C. Housed in a compact 0805 (2012 metric) package with dimensions of 2.15 mm length, 1.35 mm width, and 0.65 mm height, it functions as a slow-blow protective component.

Ptc Resettable Fuses Feature Summary

Provides overcurrent protection through polymer positive temperature coefficient technology
Offers automatic circuit restoration after fault conditions clear
Designed for surface mount assembly on printed circuit boards

Ptc Resettable Fuses Applications

Portable electronic devices requiring low-voltage circuit protection
Consumer electronics with limited space constraints
Battery-powered equipment needing overcurrent safeguards

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix AF2E confirms the 0805 package and 9V rating. Confirm RoHS compliance status via official documentation. Check moisture sensitivity level requirements for storage and handling. Ensure the supplier provides valid traceability certificates. Validate that the ordering code matches the exact electrical specifications required for the design.

Ptc Resettable Fuses Selection Notes

Select this component when a low holding current near 500 mA is required for 9V circuits. The high initial resistance distinguishes it from lower-resistance alternatives in the same series. Consider the 0805 footprint compatibility with existing board layouts. Evaluate the slow-blow characteristic against transient surge requirements. Compare thermal performance limits against ambient operating conditions.

Ptc Resettable Fuses Part Context

This part belongs to the Bel Fuse 0ZCK series of low-profile SMD PTC resettable fuses. The series targets applications demanding compact protection solutions. The 0ZCK designation indicates specific material and dimensional characteristics.
