AxiAL LEAdEd RESiSTORS

Series 100 & 200 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 dis-
tributed 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.
Two distinctly different ceramic materials are available in each size to afford the designer
with unique components to meet the most demanding requirements:
Type SP
resistors are composed of
materials that withstand high operating
temperatures resulting in high power
dissipation. Maximum continuous oper-
ating temperature is specified at 350°C.
This type is suitable for use in oil without
an oil-resistant coating.
Type AS
resistors are best suited for high
energy and voltage pulse applications.
Maximum continuous operating tempera-
ture 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.

Typical Applications
Series 100 & 200 resistors are ideal for applications such as:
• Soft Start/In-rush Limiters
• RC Snubber Circuits
• Spark-Gap Limiters
• Parasitic Suppression
• High Voltage Power Supplies
• Pulse Waveform
• EMI/EFI Test Circuits
As alternatives
to hard to find carbon composition resistors, Globar 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.

resistance Value (Ω)
For ≥ 10 Ω: First 2 digits
are significant figures, third
digit is number of zeros to
follow, e.g. 101 = 100 Ω
For < 10 Ω An R replaces
the decimal point,
e.g. 7R5 = 7.5 Ω

1. Rated Power: De-rate linearly to 0 Watts at 230°C for Type AS. De-rate linearly to 0 Watts at 350 °C for Type SP.
2. Allowable peak energy/voltage will depend on the resistance value and pulse width. Energy ratings are based on pulse
< 10 milliseconds. Type SP rating can be substantially greater for longer pulses. Consult Kanthal Globar.
3. Peak Current Ratings presume energy approaching rated peak energy values. Allowable current can be higher for lower
energy values. Consult Kanthal Globar.
4. Excludes caps/leads and coating.
