0ZRV0033FF1A

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRV0033FF1A is a radial leaded PTC resettable fuse designed for through-hole mounting. It features a ceramic construction with a holding current of 330 mA and a maximum voltage rating of 277 VDC, with an interrupt rating of 305 V. The device operates within a temperature range of -40°C to +85°C. This component provides overcurrent protection by increasing resistance significantly upon fault detection, automatically resetting once the fault condition is removed and the device cools.

Ptc Resettable Fuses Feature Summary

• Ceramic PTC construction for reliable thermal performance
• Automatic reset capability after fault removal
• Radial leaded package suitable for through-hole applications

Ptc Resettable Fuses Applications

• AC/DC power supply input protection
• Battery pack circuit protection
• Consumer electronics overcurrent safeguarding

Ptc Resettable Fuses Procurement Notes

Verify that the specified voltage ratings align with the system's maximum operating conditions. Confirm that the physical dimensions and lead spacing match the target PCB footprint. Ensure the ambient temperature environment does not exceed the rated limits to maintain proper holding current characteristics during operation.

Ptc Resettable Fuses Selection Notes

Select this component when high-voltage DC or AC line protection is required in a compact form factor. The 330 mA holding current suits low-power signal or control lines. Consider the trip time characteristics relative to the protected circuit's tolerance against transient surges before finalizing the design integration.

Ptc Resettable Fuses Part Context

This part belongs to the 0ZRV series of radial leaded PTC fuses from Bel Fuse. The series is characterized by its ceramic body and suitability for higher voltage applications compared to standard polymer types. It serves as a reusable alternative to traditional one-time fuses in space-constrained designs requiring automatic recovery.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 330 mA holding current and 277 VDC voltage rating. Verify that any replacement maintains the same radial lead configuration and ceramic construction to ensure compatibility with existing board layouts and thermal profiles.
