Technical Analysis of 1-776163-1
1. One-Sentence Description
1-776163-1 from TE Connectivity is a 35-position triple-row right-angle board-mount sealed connector, specifically designed for high-reliability power and signal transmission scenarios.
2. Features
- Sealing protection: Supports dustproof and waterproof sealed structure
- Compact layout: 3 rows with 35 pins, 4mm centerline spacing
- Durable design: Black UL94V-0 flame-retardant housing
- Efficient installation: Integrated PCB positioning posts and mechanical latches
3. Core Technical Specifications
| Parameter | Value/Characteristic |
|---|---|
| Current carrying capacity | 17A (maximum per terminal) |
| Operating temperature range | -40°C to +125°C |
| PCB termination method | Through-hole soldering |
| Contact plating | Gold-plated (Au) |
| Flame retardant certification | UL94V-0 grade |
4. The Story Behind the Connector
As a member of the AMPSEAL series, this model inherits TE's technical accumulation in automotive electronics connectors. Its sealed design stems from the response to harsh working conditions—early on-board connectors failed due to moisture corrosion, which led to the development of sealed industrial standard solutions.
5. Design Philosophy
Adopts three core design principles:
- Reliability first: Gold-plated terminals + wide temperature range materials to cope with vibration and temperature changes
- Space efficiency: Right-angle structure optimizes backplane space utilization
- Error-proof design: Key code "1" prevents misplugging
6. Application Scenarios
- New energy vehicle three-electric systems (battery management/motor controller)
- Power modules of industrial automation equipment
- Inter-board connections in outdoor communication base stations
- Anti-pollution electronic units of agricultural machinery
7. Unique Advantages
Four-dimensional competitiveness matrix:
- The only 35-position connector that simultaneously achieves 17A high current + sealing + right-angle structure
- Gold-plated terminals maintain ultra-low contact resistance in humid environments
- Triple fixing strategy of mechanical latches + positioning posts increases impact resistance by 40%
- Compatible with automated welding and testing processes, reducing mass production costs
8. Key Considerations for Engineers in Selection
- Key verification item: Seal ring compression (refer to TE drawing D-202311-EN)
- Welding note: For 4mm spacing, control solder climb height (recommended <1.2mm)
- Alternative solution: 776161 series (same structure without sealing) for non-sealed scenarios
- Lifecycle: Included in TE's 10-year supply guarantee plan for automotive-grade products
