In this article, we will delve deep into the features, specifications, working principles, applications, and benefits of the SF152E SEFUSE Thermal Fuse.

Understanding Thermal Fuses

A thermal fuse is a safety device that interrupts the electrical circuit when the temperature exceeds a specified limit. Unlike conventional fuses that respond to excessive current, thermal fuses react to overheating, making them crucial for preventing fires and damage caused by high temperatures.

Thermal fuses are commonly found in home appliances, industrial machines, and electronic circuits, where temperature control is essential. The SF152E SEFUSE is designed to disconnect power when the temperature reaches 157°C, ensuring safe operation and protecting sensitive components from heat-related damage.

Key Features of SF152E SEFUSE Thermal Fuse

The SF152E SEFUSE Thermal Fuse is engineered to provide maximum safety and efficiency. Here are some of its standout features:

3. Compact and Reliable Design: The small size allows it to be easily integrated into various devices without taking up much space.

4. One-Time Operation: Unlike resettable fuses, this single-use fuse permanently cuts off the circuit when activated, ensuring a fail-safe mechanism.

5. High-Quality Manufacturing: Manufactured by Nikkoe Electronics, it meets international safety standards for electrical components.

6. Lead Configuration: Designed for easy installation in different electronic and electrical systems.

7. RoHS Compliant: Environmentally friendly and free from hazardous substances.

How SF152E SEFUSE Thermal Fuse Works

The working principle of a thermal fuse is straightforward yet highly effective. The SF152E SEFUSE contains a heat-sensitive organic pellet inside its casing. Under normal operating conditions, the electrical circuit remains closed, allowing current to flow uninterrupted.

When the temperature reaches 157°C, the organic pellet melts, triggering the internal mechanism to separate the electrical contacts. This permanently disconnects the circuit, preventing overheating, fire hazards, or damage to connected components.

Since the fuse is a one-time-use component, it needs to be replaced after activation. This ensures maximum safety, as the device will not resume operation until the faulty component causing overheating is identified and fixed.
