Product Description
The VH 3.96 is a 3.96 mm pitch wire-to-board connector designed for medium to high current harness-to-PCB power/signal links. It is available in vertical (top-entry) and right-angle (side-entry) SMT variants for automated assembly. The connector features polarization to prevent mismating, optional latch/friction-lock mechanisms, and reinforced solder hold-downs for improved pull-out and vibration resistance. It suits appliances, power supplies, LED drivers, and industrial control equipment.
Key features
- Pitch: 3.96 mm; positions: standard 2–12 (additional circuits on request)
- Mounting: SMT; vertical (top-entry) and right-angle (side-entry) options
- Safety and structure: polarized/keyed; optional latch or friction lock; protective shroud with clear tactile mating
- Mechanical reinforcement: large solder pads, metal hold-downs/side solder tabs, board-lock designs for enhanced retention and anti-vibration performance
- Mating components: compatible with matching series crimp terminals and housings; supports common wire gauges (approx. AWG 16–22, depending on terminal)
- Materials and plating: insulator PA66/PA9T, UL94V-0; contacts copper alloy with nickel underlayer + matte tin, optional selective gold on contact area
Electrical performance (typical; refer to datasheet)
- Rated current: up to ~10 A per contact depending on wire gauge, circuit count, and temperature rise criteria
- Rated voltage: commonly up to 250 V AC/DC
- Contact resistance: ≤ 10 mΩ (typical)
- Insulation resistance: ≥ 1000 MΩ
- Dielectric withstanding voltage: ≥ 1500 VAC for 1 minute
Environmental and reliability
- Operating temperature: −25 to +105 °C
- Lead-free reflow compatible; halogen-free options available
Assembly and soldering
- Supplied in tape-and-reel for high-speed pick-and-place; optional pick-up cap/locating features
- Recommended PCB land patterns and stencil apertures provided; reflow profile per J-STD-020
- For larger bodies, consider increased paste volume and auxiliary retention; exercise care with double reflow
Compliance and documentation
