Widest range in the industry!
High performance for low cost
Tolerances to ±0.1%, an RCD exclusive!
Low inductance version available (specify opt.’X’)
For improved stability & reliability, T Series is available
with 24 hour burn-in (specify opt.’EQ’)

Standard Series T:
Tubular design enables high power at
low cost. Specialty high-temp flame resistant silicone
ceramic coating holds wire securely against ceramic core
providing optimum heat transfer and precision perfor-
mance (enabling resistance tolerances to 0.1%).

Option J: Push-In Bracket (12W - 225W)
Units are supplied with pre-assembled push-in
slotted brackets. Brackets may be purchased
separately, specify T50-PIB, T80-PIB, etc.
(order 2 brackets for each resistor)
.040 x 2”
Option T: Tapped
Single or multi-tapped units avail.
Power rating is reduced by 10%
per tap. Indicate resistance value
and wattage required per section
when ordering.
Opt. A: Axial Lead
(illustrated)
Opt. R: Radial Lead
Lead wires are attached to lug
terminals to enable soldering direct
to PCB. The resistor body can be
supported by leads up to 25W size.
Option L: Insulated Leads
Stranded wire is soldered to lug
terminals and insulated with shrink
tubing. Also available ring terminal
(Opt LR), quick-connect male (LM),
female (LF), and various others.
Option V: Adjustable
Exposed winding enables adjustment
of resistance value. Slider divides
wattage rating proportionally.
Available on edgewound and
standard winding. Do not over-tighten.
