The term **2480** is commonly encountered in the electronics industry in two primary contexts: as an **SMD (Surface Mount Device) package size** or as a **specific component part number** (most notably high-power resistors or specialized integrated circuits). Below is a breakdown of the electronic parts associated with this designation. --- ### 1. 2480 SMD Package (Imperial/Metric) In the world of passive components (resistors and capacitors), "2480" refers to the physical dimensions of the component. | Dimension | Measurement (Imperial) | Measurement (Metric) | | :--- | :--- | :--- | | **Length** | 0.24 inches | 6.0 mm | | **Width** | 0.80 inches | 20.0 mm | **Note:** The 2480 package is unique because its width is significantly larger than its length. This is typically used for **High-Power Current Sense Resistors** or **Shunt Resistors**, where a wide terminal surface is required to dissipate heat and handle high current loads. --- ### 2. Common Components with "2480" Part Numbers Several manufacturers use "2480" as part of their identification codes. Here are the most common examples: #### A. Power Resistors (e.g., Ohmite 2480 Series) These are heavy-duty resistors designed for industrial applications. * **Purpose:** Used for motor controls, power supplies, and braking systems. * **Features:** Often encapsulated in aluminum or ceramic to withstand high temperatures. #### B. Telecommunications ICs (e.g., MT2480) Some legacy or specialized integrated circuits use this number. * **Type:** V.90/V.92 Modem Controller or Data Pump. * **Function:** Handles signal processing for dial-up communication or embedded data transmission. #### C. Connectors (e.g., Molex or TE 2480 Series) * **Type:** High-density headers or wire-to-board connectors. * **Application:** Used in automotive electronics or internal computer bus connections. --- ### 3. Key Technical Specifications If you are looking at a **2480 Resistor**, you will likely encounter these specifications: | Feature | Typical Value/Range | | :--- | :--- | | **Power Rating** | 1W to 5W (depending on mounting) | | **Tolerance** | ±1% to ±5% | | **Material** | Metal Plate or Thick Film | | **Mounting** | Surface Mount (SMT) | --- ### 4. Identification Tips To identify exactly which "2480" part you have, check the following: 1. **Marking Code:** If it's a resistor, it may have a 3 or 4-digit code (e.g., "R010" for 10 mOhms). 2. **Logo:** Look for manufacturer logos like *Ohmite*, *Vishay*, or *Molex*. 3. **Context:** Is it on a power supply board (likely a resistor) or a communication board (likely an IC)?
