Interactive Model Generator
Enter dimensions and select material/plating/packaging. The system automatically generates standard model codes. If any dimension has decimals, multiply each by 10, round, pad each to 2 digits, then concatenate.
Coding Rules
Model codes use HCSP-SizeMaterialPlating-Packaging format. Size represents Length × Width × Thickness (mm). All integers: concatenate directly (15×3×10 → 15310). Any dimension has decimals: multiply each by 10, round, pad each to 2 digits, then concatenate (10×1.3×2 → 100+13+20 → 1001320).

Thickness determines electrical performance and thermal capacity after stamping; default thickness is the third segment in size code.
Default plating is Nickel (N). If other plating thickness is needed, specify μm requirements in the order.
Packaging quantity is customizable; codes remain BK / TR regardless of quantity.
Version suffix (e.g., "-A") or special process suffix may be appended to match drawing versions.
