100 & 200 Series
Bulk Ceramic Axial Lead Resistors
(continued)
100 & 200 Series Axial Leaded Non-Inductive Bulk
Ceramic Resistors provide excellent performance
where high peak power or high-energy pulses must
be handled in a small size. The advantage of the bulk
construction is that it produces an inherently non-
inductive resistor; and it allows energy and power to
be uniformly distributed through the entire ceramic
resistor body — there is no film or wire to fail. We
offer a full line of rugged, reliable ceramic resistors
— including custom designs. Three distinctly dif-
ferent ceramic materials are available in each size to
afford the designer with unique components to meet
the most demanding requirements.
As alternatives to hard to find carbon composi-
tion resistors, composition resistors can be used as
drop-in replacements for 1 and 2 watt sizes. Much
larger sizes, up to 70 watts in a single component,
are available for new or re-designs where an array of
smaller resistors may have been previously required.
FEATURES
• Non-inductive “bulk ceramic” resistor
• Uniform distribution of energy throughout resistor
body
• Replacement of Carbon Composition Resistors
• Large peak energy in small size
• High power dissipation (Type SP)
• High voltage and energy absorption (Type AS)
• Through-hole or post mountable
TYPE SP
MATERIAL TYPES
TYPE AS TYPE BA
Withstands high operat-
ing temperatures resulting
in high power dissipation.
Maximum continuous
operating temperature is
specified at 350°C. This
type is suitable for use in
oil without an oil-resistant
coating.
Best suited for high energy
and voltage pulse applica-
tions. Maximum continu-
ous operating temperature
is specified at 230°C. The
standard dielectric coating
is recommended for use
in air, and the oil-resistant
coating is recommended
for use in oil.
Best suited for high energy and voltage pulse
applications where the required resistance
value is above the resistance values available
in Type SP and Type AS resistors. Maximum
continuous operating temperature is specified
at 230°C. The standard dielectric coating is rec-
ommended for use in air, and the oil-resistant
coating is recommended for use in oil.
