~~**Surface-mount Fuses** Fundamentals~~

## ~~a~~ **Overview** 

TE Circuit Protection offers the widest selection of 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. 

TE Circuit Protection 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. 

## ~~a~~ **Multi-layer Design for Chip Fuses** 

The multi-layer design has the benefit of exposing more fuse element surface area to the glass-ceramic absorption material. When the fuse elements open, there is more material for the vaporizing fuse metals to absorb into, resulting in a very efficient and effective quenching of the fuse arc. 

Figure 1 compared the multi-layer design of our SFF fuses with standard glass coated designs. The glass coated designs rely on the coating on only one side of the fuse element to absorb the vaporizing fuse material when it opens. Therefore, there is much less absorption material available to absorb the fuse metals. The result can be prolonged arcing and possible coating breach.

Figure 2 shows how the absorption characteristics of the two designs differ. The multi-layer design indicates a clean separation with the fuse element evenly diffusing into the surrounding ceramic substrate. In the glass coated design, the element diffusion takes place in a small portion of the device and is only absorbed by the glass material directly above the area of failure. **Multi-layer Design Single-layer Glass Coated Design** 

## ~~a~~ **Wire-In-Air Design for 2410SFV Fuses** 

The 2410(6125) is a Wire-In-Air SMD Fuse which is very suitable for secondary level over current protection applications. 

Figure 3 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.

Temperature Derating<br>A fuse is a temperature sensitive device. Therefore, operating temperature will have an effect on fuse performance and lifetime.<br>Operating temperature should be taken into consideration when selecting the fuse current rating. The Thermal Derating Curve for<br>surface mount fuses is presented in Figure 4. Use it to determine the derating percentage based on operating temperature and<br>apply it to the derated system current.<br>[a] | Figure 4<br>1206/0603/0402 Series 2410 Series<br>Temperature Effect on Current Rating Temperature Effect On Current Rating<br>105 110<br>100<br>95 105<br>9085 100<br>80 95<br>75<br>70 90<br>65<br>60 85<br>5550 SS 80 =<br>45 75<br>40<br>35 70<br>3025 65<br>2015 S525s=2=. 60 MSS==Sea=e<br>10 55<br>50 Bee aa ee 50 eee<br>-55 -35 -15 5 25 45 65 85 105 125 145 -55 -35 -15 5 25 45 65 85 105 125<br>Maximum Operating Temperature (°C) Maximum Operating Temperature (°C)<br>% De-rating % De-rating<br>**----- End of picture text -----**<br>


## ~~a~~ **Pulse Cycle Derating** 

Once the I[2] t value for the application waveform has been determined, it must be derated based on the number of cycles expected over the system lifetime. Since the stress induced by the current pulse is mechanical in nature, the number of times the stress is applied has significant bearing on how much derating must be applied to the fuse rating. Figure 5 presents the current pulse derating curve for our surface-mount chip fuses up to 100,000 cycles.

## ~~a~~ **Selecting Surface-mount Fuses** 

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. 

## ~~a~~ **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.

## ~~**Surface-mount Fuses** High-Current-Rated Chip Fuses I ‘ ESE~~ 

The monolithic multilayer design of the TE Circuit Protection high-current-rated chip fuses helps to provide some of the highest current ratings available in the 1206 size and enhances high-temperature performance in a wide range of circuit protection designs. The devices’ small size, high reliability and strong arc suppression characteristics make them suitable for overcurrent protection of power supplies, servers, communications equipment, voltage regulator modules, and other high-current, small size applications. 

## **Benefits** 

- Glass ceramic monolithic structure provides stability in application cycling 

- High-current rating in a small package allows more efficient use in system space 

- Strong arc suppression in overcurrent conditions 

## **Features** 

- Lead free materials and RoHS compliant 

- Halogen free (refers to: Br = 900ppm, Cl = 900ppm, Br+Cl = 1500ppm) 

- Monolithic multilayer design 

- High-temperature performance 

- -55°C to +125°C operating temperature range 

## **Applications** 

- Communications equipment 

- Voltage regulator modules 

- Power supplies 

- Servers

## ~~**Surface-mount Fuses** Slow-Blow Chip Fuses Cr~~ 

Available in industry standard 1206 and 0603 chip sizes, TE Circuit Protection’s slow-blow chip fuses help provide overcurrent protection on systems that experience large and frequent current surges as part of their normal operation. 

The slow-blow chip fuse’s monolithic, multilayer design helps provide some of the highest current ratings available in the 1206 and 0603 footprints and enhances high-temperature performance in a wide range of circuit protection designs. The devices’ small size, high reliability and strong arc suppression characteristics make them suitable for overcurrent protection of power supplies, capacitor filter banks, LCD (Liquid Crystal Display) backlight inverters, electric motors and portable electronics. 

## **Benefits** 

- Time-delayed design prevents nuisance openings in pulsed and high inrush current applications 

- Small size with high-current ratings 

- Strong arc suppression characteristics 

## **Features** 

- Lead free materials and RoHS compliant 

- Halogen free 

- (refers to: Br 900ppm, Cl - 900ppm, Br+Cl < 1500ppm) 

- Monolithic multilayer design 

- High-temperature performance 

• -55°C to +125°C operating temperature range
