- Anatomy le Lintlha tsa Bohlokoa
4.1 Likarolo tsa Mechini
| Sebopeho | Boleng bo Tlwaelehileng | Morero |
| Pin e bohareng Ø | 3.175 limilimithara | E jara pontšo |
| Shell Ø | 8.25 limilimithara | Fatše le thebe |
| Mohala o moholo Ø | 7 limilimithara | E amohela coax e tloaelehileng |
| Lipotoloho tsa ho nyalana | 100–5,000 | Boemo ba nako e telele |
| Matla a ho nyalana | 0.5-3 kgf | Maikutlo a mosebelisi + pontšo ea botšepehi |
Khetho ea thepa e ama litšenyehelo le ts'ebetso. Brass e nang le nickel e sebetsa bakeng sa mesebetsi ea boemo ba pele; alloy ea koporo e nang le 15 µin khauta e hanela oxidation ho li-SKU tsa pele.
4.2 Lipalo tsa Motlakase
- Hona joale: ho fihla ho 1 A ho 12 V DC (tšebeliso e tloaelehileng ea bareki).
- Kopana le khanyetso: 30 mΩ ea pele, 80 mΩ ka mor'a tlhahlobo ea bophelo.
- Insulation resistance: ≥100 MΩ ho 500 V DC.
- E mamella voltage: 500 V AC bakeng sa 60 s.
- Tšitiso:
- Molumo: ha o hlalosoe ka thata, hangata 50–100 Ω.
- Motsoako kapa S/PDIF: sepheo sa 75 Ω; likarolo tsa lefatše la 'nete hangata li lula haufi le 45–60 Ω ka lebaka la meeli ea geometry.
Likhetla tse nang le lebota le tšesaane le sebaka se matla sa dielectric se ntlafatsa ts'ebetso ea 'nete empa e eketsa litšenyehelo.
- Mebala ea Coding le Likarolo tsa Lipontšo
| Mmala | Tšebeliso ea Pele | Lintlha Tse Eketsehileng |
| Khubedu | Molumo o ka ho le letona | Kamehla e kopantsoe le bosoeu kapa botšo |
| Bosoeu / Botsho | Molumo oa kanale e ka ho le letšehali | Black e hlaha meleng e meng ea lihlahisoa tsa Asia |
| Bosehla | Video e kopaneng | Tsela ea video ea PAL/NTSC SD |

Eseng kamehla. Board-mount e sebelisa maoto a solder; panel-mount e itšetlehile ka likhoele tsa linate. - Ke li-cycle tse kae tsa ho nyalana tse ka khonang ho phela?
Hoo e ka bang 100. Diyuniti tsa Premium tse nang le khauta li ka fihla li-cycle tse 5,000. - Na S/PDIF e feta RCA ehlile ke "digital"?
E na le molapo o nang le likarolo tse peli ho 0.5 V pp ka IEC 60958-3. - Ke hobane'ng ha khetla e khubelu e tšoanang e hlaha bakeng sa video ea molumo le likarolo?
Ho arolelana mebala ea lefa; kamehla hlahloba label e hatisitsoeng ho qoba cross-wiring. - Ke maemo afe a polokelo a bolokang thepa e le ncha?
10 °C-30 °C, - Nka qoba ho hola ha litelu joang lijekeng tse entsoeng ka tin?
Hlalosa matte tin holim'a koporo 'me u boloke li-finish ka tlase ho 3 µm. - Na lipolasetiki tse tsosolositsoeng li bolokehile bakeng sa matlo?
Regrind ho fihla ho 10% e tloaelehile, empa kamehla kopa lintlha tsa UL tsa ho chesa.
