100 & 200 Series
Bulk Ceramic Axial Lead Resistors
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 noninductive 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 different 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 composition 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.
F e at u r e s
• 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
M at e r i a l T y p e s
Type
SP
Withstands high operating 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.
Appplications
Type
AS
Best suited for high energy
and voltage pulse applications. Maximum continuous 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.
• Soft Start/In-rush Limiters
• RC Snubber Circuits
• Spark-Gap Limiters
• Parasitic Suppression
• High Voltage Power Supplies
• Pulse Waveform
• EMI/EFI Test Circuits
• RF Dummy Load Circuits
• Capacitor Dump Circuits
Type
BA
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 recommended for use in air, and the oil-resistant
coating is recommended for use in oil.

0 Watts at 230°C for Type AS and BA.
Derate linearly to 0 Watts at 350 °C for
Type SP.
