Tubular Radial Terminal
Wirewound for PC Board Applications
FEATURES
• Radial construction for direct
insertion into printed circuit
boards; fit standard 0.10 inch
matrix boards with standard
0.046 inch diameter holes.
Provides a built in stand-off to
reduce board temperature.
• Space saving radial terminals
reduce the total length require-
ment compared to axial terminal
resistors and increase packaging
density possibilities.
• Flame resistant lead free vitre-
ous enamel coating.
• RoHS compliant; add “E” suffix
to part number to specify.

SPECIFICATIONS
Material
Core: Ceramic.
Coating: Vitreous enamel except
for values above 4.7K (3W) and
7.5K (5W), which are supplied in
silicone-ceramic coatings.
Terminals: Solder coated radial.
#20 ga. tinned terminals require
0.046 in. (1.168 mm) holes (2).
RoHS solder composition is 96%
Sn, 3.5% Ag, 0.5% Cu
Derating: Linearly from
100% @ +25°C to 0% @
+350°C.
Note: Values above 3.9K (3W)
and 8.2K (5W) involve very fine
resistance wire and should not
be used in critical applications
without burn-in and/or thermal
cycling.
Electrical
Tolerance: ±5% (J)
(other tolerances available).
Power rating: Based on 25°C free
air rating.
Overload:
3 watt: 5 times rated wattage for
5 seconds.
5.25 watt: 10 times rated watt-
age for 5 seconds.
Temperature coefficient: ±260
ppm/°C.
