<div>Jupiter:
22#的

單條0.08的是40AWG的,65/0.08是22AWG的.
UL style 20276 要求最小導(dǎo)體是40AWG的,而你這個(gè)規(guī)格是22AWG,可做,但還要有合適的芯線(xiàn)style,如10272.

芯線(xiàn)80C 30V應(yīng)該都沒(méi)有問(wèn)題的，得看下你們廠(chǎng)的20276認(rèn)證單，上邊會(huì)有材質(zhì)以及皮厚的，再選合適的芯線(xiàn)代號(hào)，不過(guò)看你的絕緣和外被都是用PVC的，有沒(méi)有什么特性要求呢，為什么會(huì)采用20276
