Littelfuse 0476 Replacement 6125 2410 1808 Wire In Air Time Delay Suface Mount Fuse 250V 2A

 

 

Overview

 

Ao littel surface mount fuses available for addressing a broad range of overcurrent protection applications. Helping to prevent costly damage and promote a safe environment for electronic and electrical equipment, our single-use chip fuses provide performance stability to support applications with current ratings from .5A up to 20A.

Ao littel also offers the telecom FT600 fuse for telecommunications applications. This telecom fuse helps comply with North American overcurrent protection requirements,including Telcordia, GR-1089, TIA-968-A (formerly FCC Part 68), and UL60950 3rd edition

 

The multi-layer design 2410(6125) is a Wire-In-Air SMD Fuse which is very suitable for secondary level over current protection applications.
Compared our straight wire element design 2410SFV fuses with normal corrugating wire design fuse. The straight wire element in air performs consistent fusing and cutting
characteristics together with excellent inrush current withstanding capability.
Introduced PCB assembly technology into 2410SFV fuses design and manufacture, we achieved on lead free completely and no end cap falling off risk comparing with traditional ceramic body with end cap fuse.

Surface Mount Fuse Selection Flowchart

 

However, the basic considerations for fuse selection are shown in the flowchart presented in Figure 6. Following this flow chart
will help you select a fuse best suited for your application conditions.

Littelfuse 0476 Replacement 6125 2410 1808 Wire In Air Time Delay Suface Mount Fuse 250V 2A Slow Blow Lead Gold Plated

 

Step 1 – Determine Steady State Fuse Current Rating 

 

Apply Standard Steady State Derating (75%) [Ifuse ≥ Isys/0.75]  ⇒ Apply Temperature Derating [Ifuse ≥ Isys/0.75/Ktemp] ⇒ Steady State Fuse Current Rating ⇒ Step 2 –Determine Pulse Waveform by Calculating I2t ⇒  Step 3 –Apply Pulse Cycle Derating     ⇒   Step 4 –Apply Pulse Temperature
Derating     ⇒  Step 5 – Apply Derating for Variance in the Circuit  ⇒  Step 6 – Select Fuse Current
Rating for Pulse Environment ⇒ Step 7 – Select Fuse Current Rating (use higher value between Step 1 and Step 6)  ⇒  Step 8 – Check Voltage Rating  

 

 

Selecting Surface Mount Fuses

 

SMD Fuse selection seems straightforward, in that, you pick one which has a current rating just a bit higher than your worstcase system operating current. Unfortunately, it’s not that simple. There are derating considerations for operating current and application temperature. Turn-on and other system operations (like processor speed changes or motor start up) cause current surges or spikes that also require consideration when selecting a fuse. So selecting the right fuse for your application is not as simple as knowing the nominal current drawn by the system.

 

 

Surface Mount Fuse Temperature Derating Comparision

 

A SMD fuse is a temperature sensitive device. Therefore, operating temperature will have an effect on fuse performance and lifetime.Operating temperature should be taken into consideration when selecting the fuse current rating. The Thermal Derating Curve for surface mount fuses is presented in below Figure . Use it to determine the derating percentage based on operating temperature and apply it to the derated system current.
