Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'feed' (кормить). The word is a compound noun related to 'through'.
- Avoid translating as 'сквозной' alone; more specific terms like 'проходной изолятор' or 'ввод' are used in technical contexts.
Common Mistakes
- Using it as a verb (e.g., 'to feedthrough a signal').
- Confusing it with 'feedback'.
- Misspelling as 'feed-through' (hyphenated form is also acceptable but less common in technical specs).

Frequently Asked Questions
Both 'feedthrough' and 'feed-through' are found, but the solid form is more common in modern technical documentation.
No, it is almost exclusively a noun. The verbal idea is expressed with phrases like 'pass through' or 'feed through' (as a phrasal verb).
A 'coaxial feedthrough' is common for transmitting radio frequency signals through a shielded enclosure.
No, it is a highly specialized technical term unlikely to be encountered outside engineering, laboratory, or industrial contexts.
