RCD’s RW Series are manufactured on an exclusive automated
system, resulting in significant cost savings. The all-welded
ceramic core design results in excellent performance levels,
especially in regards to overload capability, TCR, noise characteristics, and load life stability. Coating is flame resistant and
offers excellent moisture and solvent resistance.

OPTION FF FUSE RESISTOR APPLICATION GUIDE
1. Opt. FF fusible version is available from 0.1Ω - 2.4K (RW1FF=1.2K max)
2. Fault level must be suitable to safely open the resistor. Option FF parts ≥1W
are desgned to blow within 20S at 15x rated power, 20x if<1Ω (preferable if
fault level is double this level to ensure quick fusing time).
3. Maximum fault must not exceed 200x W rating, or voltage rating, whichever
is less (increased levels avail).
4. For customized fusing, complete RCD’s fuse questionnaire, or advise the
desired fusing wattage/current, min/max blow times, continuous power, surge
reqts, ambient temp, physical constraints, fault voltage, inductance, etc.
5. Fuse types shouldn’t be mounted in contact with other components or PCB.
6. Residual resistance is ≥100x initial value after fusing.
7. Verify selection by evaluating under the full range of fault conditions. Place
resistors inside a protective case when testing under overload.
