FDH Heat Shrinkable Female Terminals
FDH heat shrinkable female terminals are copper receptacles with a heat-shrink sleeve for mating with flat tabs. The 22 listed models cover 0.5–6 mm² conductors.
- Choose red, blue or yellow by conductor section.
- Compare NEMA tab size, table thickness and B/D/d/L/E dimensions by model.
- Source operating range: −55 to +125 °C; shrink begins at 80 °C.
Overview
FDH Heat Shrinkable Female Terminals are copper female tab receptacles with a heat-shrink sleeve. The supplied catalog lists 22 models across three conductor groups. Select the female terminal by conductor section, mating tab size and the dimensions of the connection.
Features
- Heat-shrink sleeve: the catalog specifies an initial shrink temperature of 80 °C and a minimum temperature of 130 °C for complete shrinkage.
- Copper terminal: the conductive terminal material is listed as copper.
- Three conductor groups: red, blue and yellow models cover different conductor sections and dimensional sizes.

Selection Guide
Match the conductor section and NEMA tab size first, then check thickness and B/D/d/L/E dimensions against the mating connection and available space. Include the complete FDH model code and required quantity in an inquiry.
