The part number **162J56** typically refers to a specific type of **Precision Wirewound Resistor**. These components are known for their high stability, low temperature coefficient, and accuracy in power-handling applications. --- ## 1. Technical Specifications The alphanumeric code follows a standard naming convention used by many electronic component manufacturers. | Feature | Description | | :--- | :--- | | **Component Type** | Precision Wirewound Resistor | | **Resistance Value** | 1.6 kΩ (1600 Ohms) | | **Tolerance** | ±5% (indicated by the 'J' suffix) | | **Construction** | Metal wire wound around a ceramic core, usually encapsulated in silicone or epoxy. | | **Voltage Rating** | Dependent on physical size (wattage), usually up to 500V - 1000V. | --- ## 2. Component Breakdown * **162**: This represents the resistance value. The first two digits (16) are significant figures, and the third digit (2) is the multiplier ($10^2$). Thus, $16 \times 100 = 1600$ Ohms. * **J**: This is the industry-standard tolerance code. **J** stands for **±5%**. * **56**: This often indicates the series or the physical package size (e.g., a 5-watt or 10-watt rating depending on the specific manufacturer's catalog). --- ## 3. Key Characteristics * **High Power Dissipation:** Because they are wirewound, they can handle higher temperatures and power surges compared to film resistors. * **Inductance:** Note that standard wirewound resistors have inherent inductance. They are generally not suitable for high-frequency RF applications unless specified as "Non-Inductive." * **Durability:** They are resistant to moisture and environmental stressors due to their thick protective coatings. --- ## 4. Typical Applications 1. **Current Sensing:** Used in power supplies to measure current flow. 2. **Voltage Dividers:** Employed in precision circuits where stability is required over time. 3. **Industrial Controls:** Used in heavy machinery where power surges might occur. 4. **Audio Equipment:** Sometimes used in high-end speaker crossovers. ---
