Introduction

A fuseholder is a device designed to protect electric circuits, wiring and other conductive devices by quickly disconnecting electrical power in an emergency situation. SPFRHD4001ST is an ultra-slim fuseholder module which is designed for use with popular 5A fast-blow SMD fuses. The fuseholder has a small footprint and is ideal for applications where space is limited.

Overview

The SPFRHD4001ST is a thermal fuseholder that accepts and actively dissipates heat from the corresponding 5A fast-blow SMD fuse. It is designed for PCB layouts with a thickness of only 0.8mm and excellent thermal performance. It has a wide temperature range of -55C to +125C for reliable operation. The housing is designed with a protection tab that prevents shorts on the board. It is also RoHS Compliant, so it meets environmental protection regulations and requirements.

Benefits

The SPFRHD4001ST is the ideal solution for limited space applications. Its ultra-slim design not only reduces PCB footprint but also reduces power consumption. It also allows for excellent thermal performance and boasts a temperature range of -55C to +125C. To avoid short circuits, it is designed with a tab that prevents shorts on the board. In addition, its RoHS Compliant design ensures it meets environmental protection regulations.

Application Field

The SPFRHD4001ST is ideal for use in a variety of electrical applications including:- Automotive Electronics- Industrial Electronics- Military and Aerospace- Consumer Electronics- Telecom/Networking- Medical Devices- Power Supplies- Instrumentation- Renewable Energy

Working Principle

The SPFRHD4001ST is designed to quickly disconnect electrical power in an emergency situation. When the current in the circuit exceeds its rated value, the fuse ruptures and rapidly releases the energy stored in its coil. This rapid release of energy creates a high pressure wave, which is transmitted throughout the circuit, tripping the breaker and quickly shutting off the circuit. The thermal fuseholder then dissipates the remaining heat and prevents further damage.

Features

The SPFRHD4001ST offers several features and benefits that make it the ideal fuseholder for any application:- Ultra-slim design: With a thickness of only 0.8mm, it is perfect for limited space applications.- Wide temperature range: With a temperature range of -55C to +125C, it is ideal for a variety of applications.- Protection tab: The fuseholder is designed with a protection tab that prevents shorts on the board.- RoHS Compliant: The fuseholder is RoHS Compliant, so it meets environmental protection standards.

Conclusion

The SPFRHD4001ST is an ultra-slim fuseholder module designed for use with 5A fast-blow SMD fuses. Its small footprint makes it ideal for applications where space is limited. It offers features such as a wide temperature range, a protection tab, and RoHS Compliant design which make it the ideal fuseholder for any application.
