3C-2V
type of coaxial cable
3C-2V is commonly marked on low cost coaxial cable used for domestic TV signals.
It is one of the options of the Japanese cable standard JIS C 3501.
The 3 indicates approx diameter of the conductive core plus the dielectric (diameter of conductive core =0.5 mm, dielectric thickness =1.3 mm)
The C indicates a characteristic impedance of 75 ohms
The 2 indicates a solid PE dielectric core
The V indicates a single braided outer conductor (W would be double)
Nominal loss at 100 MHz is 42 dB/km.
With its narrow core it is similar to RG-59 cable; RG-6 coax cable is better shielded and has lower losses.
The public source identifies “3C-2V” as type of coaxial cable. This brief keeps that definition visible, then builds a research path around 3C-2V, type and coaxial.
Why this record matters
A short description can identify a subject without explaining its stakes. For “3C-2V”, the useful work is to connect “type of coaxial cable” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jun 5, 2023. The linked authority identifier is Q17152947. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
