Exxelia can delivery axial leads on size code 262, 263, 264, 265, 266 to allow the customer to obtain the leads spacing needed (leads spacing code = 9). In that case we recommend to bend the connections at a
distance from the ceramic body of 5mm minimum.
The above table defines the standard products, other components may be built upon request.

CERAMIC CAPACITORS
General Information
Taping : dimensions
High temperature capacitors are made of class 1 or class 2 ceramic dielectrics
featuring special compositions based upon high purity oxides to reduce ionic
conduction inherent to the presence of atoms such as sodium.
In addition, all quality controls carried out at intermediate and final production
stages (lot acceptance test under U
RC
and insulation resistance measurement
at operating temperature) are the assurance of enhanced reliability.
High temperature capacitors include :
• chip class 1 (CEC 203 to CEC 233) and class 2 (CNC 203 to 233),
• encapsulated radial leads class 1 and 2 (TCE / TCN 201 to 204),
• encapsulated axial leads class 1 and 2 (TCE / TCN 252 to 254),
• selfprotected radial leads class 1 and 2 (TCE / TCN 212 to 216)
and radial leads class 1 and 2 (TCE / TCN 263).
Mechanical stress is eliminated with replacement of epoxy by selfprotected
ceramic. This also allows the increase of the capacitance ranges and improves
the reliability.
• high voltage varnished capacitors (TCH 279 to 285)
• high capacitance value SCT Series.
They are highly recommended for operation at temperatures of up to 200°C.
Capacitors specifically designed for higher operating temperatures (e.g. TCE /
TCN 212 to 216 and TCE / TCN 263 to 266) are also available.
High temperature capacitors are made of class 1 or class 2 ceramic dielectrics
featuring special compositions based upon high purity oxides to reduce ionic
conduction inherent to the presence of atoms such as sodium.

DIELECTRIC CHARACTERISTICS
Insulation Resistance (IR)
is the resistance measured under DC voltage
across the terminals of the capacitor and consists principally of the parallel
resistance shown in the equivalent circuit. As capacitance values and hence
the area of dielectric increases, the IR decreases and hence the product (C x
IR) is often specified in Ω.F or MΩ.µF.
The Equivalent Series Resistance (ESR)
is the sum of the resistive terms
which generate heating when capacitor is used under AC voltage at a given
frequency (f).

Gold
(Solderable layer)

Margins
Silver or Silver / Palladium (electrodes contact layer)
Polymer (crack protection layer)
Nickel or Copper barrier (leaching protection layer)
Dissipation factor (DF)
is the ration of the apparent power input will turn to
heat in the capacitor:
DF = 2π f C ESR
When a capacitor works under AC voltage,
heat power loss (P),
expressed in
Watt, is equal to:
P = 2π f C Vrms

DF
EQUIVALENT CIRCUIT
Capacitor is a complex component combining resistive, inductive and capaci-
tive phenomena. A simplified schematic for the equivalent circuit is:
The series inductance (Ls)
is due to the currents running through the elec-
trodes. It can distort the operation of the capacitor at high frequency where the
impedance (Z)
is given as:
Z = Rs + j (Ls.q - 1⁄(C.q)) with
q
= 2πf
IR
Ls
Rs
C
When frequency rises, the capacitive component of capacitors is gradually
canceled up to the resonance frequency, where :
Z = Rs and LsC.q
2
= 1
Above this frequency the capacitor behaves like an inductor.
