## Description

BOJACK 20 Pcs High Quality Slow-blow Glass Fuse Fuse model:T4AL250V Fuse Current: 4A Fuse Voltage: 250V Fuse Dimension:5x20mm/0.2x0.78 Inch The role of the Slow-blow fuse：The slow-blow fuse is also called a time-delay fuse. Its delay characteristic is maintained in the circuit when it has a non-fault pulse current and can protect against long-term overload. Some circuits have a current greater than a few times the normal operating current at the switching instant. Although this current peak is very high, it occurs for a short period of time. We call it a pulse current or an inrush current or a surge current. Ordinary fuses can not withstand such currents. If such a circuit uses an ordinary fuse, it may not be able to start normally. If a larger fuse is used, it will not be protected when the circuit is overloaded. The melt of the time-delay fuse is specially processed to absorb energy. By adjusting the energy absorption, it can resist the inrush current and protect the overload.

Review: So far so good - So I was a little weary buying Chicom components. I usually stay away but this was the only one I could get of this value. Seems to work and does the job. It fits perfectly. For those of you who may not know this is the shorter fuse. You might find in vacuums, microwaves and so on

### ⭐⭐⭐⭐⭐ Saved my Ion "Game Day" speaker.
*by J***N on November 8, 2023*

Speaker was DOA. Took it apart, swapped battery, still no love. Worked when plugged in but no battery life etc... Finally determined that there is a fuse inline with battery connections. It was cracked. These were a perfect replacement, after installation, works fine and now I have spares if it happens again.
