ATC Single Layer Millimeter Wavelength Microcaps
: 111 & 116 Series
ATC PART NUMBER CODE
Design Your Own Single Layer Capacitor
ATC gives you the ability to create custom values and dimensions. When circuit board area is tight or you need to match your
stripline width, you can optimize the size and shape of required SLCs. This same technique can be used to build special values
that fall outside of the standard offerings.

Use the Standard Capacitance Value chart on pages 6 and 7 to select a code which is within the capacity range given for a
specific case size/dielectric combination.
Select a capacitance tolerance from the available tolerances listed in the Selection Chart.
The above part number describes a 100 volt, TT termination (thin film), 111 series (beveled edge) capacitor, case size S (0.018"
square nominal), CA dielectric (0 ±30 ppm/°C). This size/dielectric combination has a capacitance range of 0.4 to 0.9 pF and
available tolerances of B, C or D. 0R5 defines a capacitance value of 0.5 pF B tolerance (±0.1 pF) was selected.

Custom Values and Sizes
Optimize the best combination of length, width, thickness and dielectric material for your circuit/stripline capacitor requirements.
ATC accepts orders for our parts using designations
with
or
without
the
“
ATC
”
prefix. Both methods of defining the part number are equivalent, i.e., part
numbers referenced with the
“
ATC
”
prefix are interchangeable to parts referenced without the
“
ATC
”
prefix. Customers are free to use either in specifying or
procuring parts from American Technical Ceramics.
