DFJ-100-W

The DFJ-100-W is a precision-manufactured current-limiting fuse from an industry leading specialist in the design and production of high-quality, custom-made electrical fuses. It is designed for a wide range of applications and can serve as an ideal protection device for protecting critical electronics components and whole systems.

The DFJ-100-W has a particularly high current rating of up to 150 A at a rated voltage of 16 V, making it ideal for power electronics applications. Its extremely low hold current and total open/short circuit response time makes it suitable for a wide range of industrial and commercial applications. Additionally, its high short-circuit breaking capacity helps to protect systems from short-circuiting or current surges, which may cause costly damage and downtime.

The working principle of the DFJ-100-W is based on the reverse-conduction current-limiting technology. The device consists of two parts; a PTC thermistor and a bi-metallic element. The PTC thermistor is a temperature-sensitive element that increases its electrical resistance in response to elevated temperatures. It is connected in series with the bi-metallic element, which is connected between the power source and load. When the current either exceeds or drops below the pre-defined rated current for too long, the bi-metallic element warps and presses against the PTC thermistor, thereby increasing its electrical resistance and limiting the flow of current.

The DFJ-100-W is extremely reliable and robust. It is made of a highly durable material and is able to withstand extreme temperatures. It is designed with an in-line package that allows it to be integrated into almost any system requiring short-circuit protection. Additionally, it meets industry standards and is UL approved.

The DFJ-100-W is suitable for a range of applications, including automotive, industrial, and commercial, and is also suitable for use in harsh environments. It is designed for quick response and can protect electronic equipment from being damaged by short-circuiting or extreme loads. It is a reliable, robust, and cost-effective protection device, perfect for protecting both components and whole systems.
