FRSERIES FIXED FUSIBLE RESISTORS

■FEATURES

• Provide an excellent fusing characteristic for CIRCUIT protection in
case of overload or component failure.

• Opening th circuit safety without burning and flaming at
a emergency overload due to make use of flame proof coating.

• Coating Color: Gray(FR 1/4W, 1/2W, 1W, 2W)

• Marking: Color Code
