Dry mica open resistor candidate
Bare resistance-alloy winding mechanically held on individually split mica sheets with integral mechanically retained terminations and an open-air guarded heat path; no resin encapsulation or technical-ceramic carrier. Resistance, stability, insulation and power rating remain unqualified.

Making outline
- Manually wind bare resistance-alloy wire on dry individually split mica former sheets, mechanically clamp terminations and retain guarded open-air winding; compare resistance/stability/parasitics and insulation under independent protected excitation
- Detailed procedure and acceptance remain unresearched.
What remains unresolved
- Manufacture, quantities, suitability and complete inventory remain unreviewed.
- Current memory-first method needs source and compatibility review.
Canonical reuse assessment
"Distinct resin-independent physical construction and capability-limited power candidate, not a renamed generic wirewound-resistors set. Existing generic and handset components remain unchanged; mica card manufacture is an inference from natural sheets rather than assumed delivered built-up mica."
