Wirewound Fuse Resistors

What is a Wire-wound Fusible Resistor?
A wire-wound fusible resistor is a resistor that is designed to burn open easily when the power rating of the resistor is exceeded.
Wirewound Fuse Resistors also known as FKN, FSQ Fusible Wire Wound Resistors.
There are some similarities between Resistors and Fuses in material and structure. Fusible resistors contain both functions, as being resistor in normal condition and changed into fuse while abnormal current comes into protect machines and equipment. Since two functions performed by one resistor, the cost therefore saved FKN and FSQ fusible resistor series are produced with precision technique to get exact fusing time.

Wirewound Fuse Resistors

FKN, FSQ Fusible Wire Wound Resistors. There are some similarities between Resistors and Fuses in material and structure. Fusible resistors contain both functions, as being resistor in normal condition and changed into fuse while abnormal current comes into protect machines and equipment. Since two functions performed by one resistor, the cost therefore saved FKN and FSQ fusible resistor series are produced with precision technique to get exact fusing time.

Features:

1. It is suitable for protecting circuit boards
2. Small size.
3. Noncombustible insulating coating , solvent proof and resistant to high temperature.
4. Low temperature coefficient ±300ppm℃.
5. Uniform in fusing time .
6. Good heat-durability. Low temperature coefficient, Low noise, High load power, Nonflammability.
7. It is suitable for protecting circuit boards,Can be Fusible during the stated time for protecting the circuit once wording at the required overload voltage

Major Parameters:

1. Rated Power:1/4W～5W.
2. Resistance Range:0.1Ω～200Ω
3. Resistance tolerance :±2%、±5%、±10%

Use of Fusible Resistors: In this way, a fusible resistor serves dual functions. When the power isn't exceeded, it serves as a resistor limiting current. When the power rating is exceeded, it functions as a fuse, burning up, and becoming an open in the circuit to protect components in the circuit from excess current.
