Individual Sheet
1.Scope
This specification relates to DC ceramic disc capacitor intended for use in telecommunication and electronic devices.
2. Part number
□□□101 J 26 C0H F 6 F J 5 A □
⑴⑵⑶⑷⑸⑹⑺⑻⑼⑽⑾⑿
The part number consists of 12 sections. The meaning in each section is as follows:
⑴Capacitor type code
The type code is DCC for temperature compensating disc ceramic capacitors(Class Ⅰ) being 50V of rated voltage, DCT for high dielectric constant disc ceramic capacitors(Class Ⅱ) being 50VDC of rated voltage, DCM for both types being 500V of rated voltage, DCH for both types being 1000V up to 3000V rated voltage, DCG for both types above 3000V rated voltage, and DCS for semi-conductive disc ceramic capacitors (class III, i.e. SBBLC).
⑵Rated capacitance
The first and second digits identify the first and second significant figures of the capacitance, the third digit identifies the multiplier. The capacitance unit is pF.
⑶Capacitance tolerance
⑷Body Dimension code
⑸Temperature coefficient or temperature characteristics
⑹Rated voltage
⑺Lead diameter
⑻Lead length or taped style
⑼Lead style
⑽Lead Spacing
* For the capacitors in bulk packing only. For taped capacitors the lead spacing conform to figure 2 or figure 3.
⑾Letter symbol
The letter symbol is the code using for producing management by manufacturer only.
⑿Figure symbol 0 or 1
The figure “0” means that the products comply with European Union Di rective, i.e. the contents of environment-related hazardous substances in the products are less than the amount to be banned or controlled in RoHS directive.
The figure “1” means that there is no relative command for the products, sometimes may be omitted.

6. Marking
(1)Temperature characteristic:
The marking of class Ⅰtemperature characteristic is the color block on top of capacitor
The marking of class Ⅱ &Ⅲtemperature characteristic is symbols specified in following table.
(2) Capacitance
When rated capacitance is under 100pF the capacitance marking is value being rated capacitance in unit pF.
When rated capacitance is 100pF or over the capacitance marking is made in third digit method.
(3)Tolerance
The tolerance marking for classⅠis the symbols specified in following table.
The tolerance marking for classⅡ&Ⅲis the symbols specified in following table.
(4) Rated voltage
When rated voltage is 50V the voltage marking is symbol “___” under capacitance marking.
When rated voltage is 500V the voltage marking is symbol “ ” over capacitance marking.
When rated voltage is 1000V or over, the voltage marking is symbols “1KV”, “2KV”, “3KV”, “6KV” over capacitance marking.
(5) Manufacturer
When diameter of capacitor body is 6.5mm or under (for 50V and 500V capacitors) or diameter of capacitor body is 7.5mm or under the manufacturer’s marking is symbol“.” under the last digit of capacitance marking.
When diameter of capacitor body is over 6.5mm (for 50V and 500V capacitors) or over 7.5mm (for 1000V capacitors) the manufacturer’s marking is symbols “SHM”.
