1608 Chip One Time Slow Blow SMD Surface Mount Fuse 3A 32V For Power Management

Description Of The 1608 Chip One Time Slow Blow SMD Surface Mount Fuse 3A 32V

The R0603 slow blow surface mount fuse is perfect updated model for typical subminiature fuses with anti-surge , easy soldering, excellent performances and small size. SMT process is current trend of electronics soldering , even future because electronics devices is becoming smaller and smaller around our life.

The R06.100.3 is a surface-mount slow-blow Chip Fuse provides overcurrent protection on systems that experience large and frequent current surges as part of their normal operation. The fuse's monolithic and multilayer design provides highest current rating in the 0603 footprint and enhances high-temperature performance in a wide range of circuit protection designs. The device's small size, high reliability and strong arc suppression characteristics makes it suitable for overcurrent protection of power supplies, capacitor filter banks, liquid crystal display (LCD), backlight inverters, electric motors and portable electronics.

What's the difference between the slow blow and fast acting fuse in terms of performance and application?

A slow blow fuse is different from a fast acting fuse in its capability to withstand transient pulse currents, i.e., it can withstand the surge current upon power-on/off, thus ensuring the equipment works normally. Therefore, slow blow fuses are often called time-delay fuses. Technically, a slow blow fuse features a higher I2t value, and it requires more energy to blow, so it is more capable of withstanding pulses compared with a fast acting fuse of same rated current.

When an overcurrent occurs in a circuit, the breaking time of a slow blow fuse takes longer than that of a fast acting fuse because of the larger I2t. Is it less protected this way as some people are worried? The answer is no. Once the circuit fails, the overcurrent will last and corresponding energy released will go beyond the I2t of the fuse until it blows out. The timing difference of slow blowing and fast acting is not significant to their protection. Slow blowing will affect the protection performance only when sensitive components existing in the protected circuit need to be protected.

Due to the previous difference, slow blow and fast acting fuses are applied to different circuits. Fast acting fuses must be used in purely resistive circuits (no or fewer surges) or the circuits where IC and other sensitive components need to be protected, while slow blow fuses are preferably used in capacitive or sensitive circuits where surges occur upon power-on/off and power input/output. Apart from circuits for IC protection, most applications with fast acting fuses can be replaced with slow blow ones to enhance anti-surge capability. Contrarily, replacement of applications with slow blow fuses to fast acting ones may cause the fuse to break as soon as the equipment is switched on and fails to work.

Furthermore, economic consideration is also an indirect factor for selection because a slow blow fuse is much expensive than a fast acting one.
