FRG900-16F

Ptc Resettable Fuses Overview

The FRG900-16F is a radial leaded PTC resettable fuse manufactured by RFE/Fuzetec. It features a disc package with tin-plated copper leads, specifically 24 AWG gauge. The component is rated for a maximum voltage of 16V and holds a hold current (Ih) of 9A. It operates within a temperature range of -40°C to +85°C. This device provides overcurrent protection in electronic circuits, offering resettable functionality upon cooling after a fault condition.

Ptc Resettable Fuses Feature Summary

• Provides resettable overcurrent protection via positive temperature coefficient technology
• Utilizes a radial disc package design for through-hole mounting applications
• Constructed with tin-plated copper clad steel leads for reliable connectivity

Ptc Resettable Fuses Applications

• Telecommunications equipment circuit protection
• Consumer electronics power supply lines
• Industrial control system input/output protection

Ptc Resettable Fuses Procurement Notes

Verify the specific manufacturer designation, as sources list both RFE/Fuzetec and Fuzetec Technology Co., Ltd. Confirm the lead material specification matches project requirements, noting variations between tin-plated copper and copper clad steel across similar series parts. Ensure the voltage rating of 16V aligns with the target circuit's maximum operating voltage to prevent premature tripping or failure during normal operation.

Ptc Resettable Fuses Selection Notes

Select this component when a low-voltage, high-current resettable fuse is required for through-hole assembly. The 9A hold current makes it suitable for protecting higher current branches compared to lower-rated variants in the FRG series. Consider the 16V limit strictly; do not use in higher voltage systems. Evaluate the thermal environment to ensure the +85°C maximum operating temperature does not compromise long-term reliability in hot enclosures.

Ptc Resettable Fuses Part Context

The FRG900-16F belongs to the FRG series of radial leaded PPTC devices from Fuzetec. This series includes various current ratings such as FRG300-16F and FRG1000-16F, allowing designers to scale protection levels. The FRG900-16F specifically addresses mid-range current protection needs within the 16V constraint, serving as a cost-effective alternative to traditional fusible links in consumer and telecom hardware.

Ptc Resettable Fuses Replacement Considerations

Potential substitutes include FRG1000-16F for higher current capacity or FRG800-16F for lower current requirements within the same voltage and package family. Cross-reference numbers like RLD16P900GF may indicate compatible equivalents, but verify electrical parameters and physical dimensions before substitution.
