From 20a8a27e71404b8ac8b5f81a170ed7b4e054c53f Mon Sep 17 00:00:00 2001 From: Dennis Brentjes Date: Fri, 2 Oct 2026 09:14:22 +0000 Subject: [PATCH] fix(bom): correct Tolerance fields that contradicted their MPN 13 resistors carried Tolerance=5% while their MPN is a UNI-ROYAL 0402WG*F* part -- F is the EIA code for +/-1% (J is 5%), and LCSC confirms the 1% rating. The parts are 1%; only the metadata was wrong. Worth fixing rather than leaving: the same part number appearing with two different tolerances splits into two BOM lines under any grouping that includes the field, and it misleads anyone sizing a divider. R48 in the eFuse ladder was one of these (fixed in a9052c6) and there it was load-bearing -- at a genuine 5% the OVLO worst case reaches 17.05 V, over U3's 17 V limit, versus 14.42-15.83 V at the correct 1%. Metadata only; no circuit or part number changes.
