1. Product Overview: JMD Connectors

️· Type: These are edge card connectors, specifically designed for board-to-board connections. They are available in both plug (male) and receptacle (female) versions.
️· Range: They offer a range of connectors covering 20 to 100 circuits (pins).
️· Application: Designed for automated placement due to embossed-tape packaging. They are built according to JIS C 0806 standards.
️· Note: Specifications are subject to change.

2. Connector Types & Models

️· Plug (Male) Connectors:
- Model naming convention: `[Circuit Number]R-JMDSS-G-1-TF` (e.g., 20R-JMDSS-G-1-TF)
- Example Models: 20R, 30R, 20P
️· Receptacle (Female) Connectors:
- Model naming convention: `[Circuit Number]R-JMDSS-G-1-TF` (e.g., 20R-JMDSS-G-1-TF)
️· Model Number Significance: Circuit number indicates the number of circuits/pins available.

3. Materials & Finish

️· Contact: Phosphor bronze, gold-plated (for improved conductivity and corrosion resistance).
️· Housing: Polyamide, UL94V-0 (flame retardant material).
️· Solder Tab: Brass, copper-undercoated, tin/lead-plated (for good solderability).

4. Dimensions & Taping Specifications

️· General Dimensions (Plug & Receptacle - see table below for specific values): Dimensions provided with notations for F, S, W, W1, representing different dimensions critical for tape placement and board layout.
️· Taping Specifications Table (Example Values, see full table in original text):
