The term **34808** is most commonly associated with a specific series of high-density interconnect components manufactured by **Molex**. Specifically, it refers to the **Molex MX150™ Sealed Connector System**, a staple in automotive and industrial electronics. --- ## 1. Overview of the 34808 Series The Molex 34808 series consists of unsealed and sealed blade headers. These are designed to provide a high-performance, compact connection for power and signal applications in harsh environments. ### Key Specifications | Feature | Description | | :--- | :--- | | **Manufacturer** | Molex | | **Connector Type** | Header (Male Pins) | | **Pitch** | 3.50mm | | **Current Rating** | Up to 22.0A per contact | | **Operating Temp** | -40°C to +125°C | | **Rows** | Dual Row (usually 2x4, 2x6, 2x8 configurations) | --- ## 2. Technical Features These parts are engineered for reliability in vibration-heavy environments (like vehicle engines). * **Integrated TPA:** Most 34808 headers feature Terminal Position Assurance (TPA). This ensures the terminals are fully seated and prevents them from backing out. * **Mat-Sealed Technology:** They often work in conjunction with mat-sealed female connectors to prevent moisture ingress (IP67/IP69K ratings). * **Circuit Size:** Common variants include 8, 12, 16, and 20-circuit options. * **Mounting Type:** They are typically **Through-Hole** (Vertical or Right Angle) for secure PCB attachment. --- ## 3. Common Part Numbers The "34808" prefix is followed by four additional digits that specify the exact configuration (circuit count, plating, and color). | Part Number | Circuits | Orientation | Plating | | :--- | :--- | :--- | :--- | | **34808-0001** | 8 | Right Angle | Tin (Sn) | | **34808-0004** | 12 | Right Angle | Tin (Sn) | | **34808-0007** | 16 | Right Angle | Tin (Sn) | --- ## 4. Typical Applications Due to their rugged nature, these electronic parts are found in: 1. **Automotive:** Engine control modules (ECUs), lighting systems, and body electronics. 2. **Commercial Vehicles:** Construction equipment and agricultural machinery. 3. **Industrial:** Power controllers and ruggedized sensor hubs. --- ## 5. Mating Parts To complete a circuit using a 34808 header, you typically require the corresponding MX150 female receptacle. * **Mating Receptacle Series:** Molex 33472 * **Terminals:** Molex 33012 (Tin), 33001 (Gold/Silver) ---
