RW SERIES

Excellent performance at economy prices

Inherent stability due to all-welded wirewound construction

Wide resistance range: 0.01

Ω to 25KΩ

Standard tolerance is 5% (2% and 10% available)

Available on horizontal Tape & Reel (1W-10W), or

vertical Tape & Reel (1W-3W)

SPECIFICATIONS

TYPICAL PERFORMANCE CHARACTERISTICS

ECONOMY WIREWOUND RESISTORS

1 WATT to 10 WATT

* 0.040 lead dia. available, specify option ‘18’

** Lead length of parts supplied on tape may be shorter

RW Series resistors are manufactured on an exclusive

automated system, resulting in significant cost savings.

Ceramic core results in performance levels far superior to

conventional fiberglass cores, especially in regards to

overload capability, TCR, noise characteristics, and load life

stability. Coating is flame resistant and offers excellent

moisture and solvent resistance.

1. Opt. FF fusible version is available from 0.1

2. Fault level must be suitable to safely open the resistor. Option FF parts

are desgned to blow within 20S at 15x rated power if

≥1

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.
