TOLERANCE AND T.C. OPTIONS

OA SERIES

RCD’s OA series offers cost-effective performance for a wide range of

current shunt/sense applications. The non-insulated open-air design

features non-inductive performance and excellent stability/overload capacity.

Numerous design modifications and cutom styles are available...

current ratings up to 100A, surface mount designs, military screening/

burn-in, marking, insulation, intermediate values, etc. Custom shunts

have been an RCD specialty over 30 years! Contact factory for assistance.

Industry’s widest range and lowest cost!

Tolerances to ±0.5%, TC’s to ±20ppm

Option S: Axial lead (unformed element)

Option E: Low Thermal EMF

Option A: Stand-offs formed into lead wires

Optional pin diameters and pin spacing

TYPICAL OPERATING CHARACTERISTICS:

TEMPERATURE RANGE: -55 to +275°C

DERATING: derate power & current rating by 0.4%/°C above 25°C

OVERLOAD: 5 x rated power for 5 seconds

LOAD LIFE @ 25°C (1000 hrs): 1%

∆R

MOISTURE No Load (1000 hrs): 1%

∆R

INDUCTANCE: <10nH

TEMP. CYCLING -40°C to+125°C (1000 cycles): 1%

∆R

* TC options vary depending on size and value (consult factory for availability)
