The term **162JE** typically refers to a specific type of **Polyester Film Capacitor** (often called Mylar capacitors). In electronic component coding, this alphanumeric string defines the electrical properties of the device. --- ### 1. Decoding the "162JE" Label The code is broken down into three specific segments: the capacitance value, the tolerance, and the dielectric type. | Segment | Meaning | Value / Explanation | | :--- | :--- | :--- | | **162** | Capacitance Code | 1,600 picofarads (pF) or 1.6 nanofarads (nF) | | **J** | Tolerance | ±5% (standard precision) | | **E** | Voltage/Series | Often denotes a 250V rating or specific series (varies by manufacturer) | ### 2. Technical Specifications Most 162JE components share these physical and electrical characteristics: * **Capacitance Calculation:** * The first two digits (16) are the significant figures. * The third digit (2) is the multiplier ($10^2$). * $16 \times 100 = 1,600 \text{ pF} = 1.6 \text{ nF} = 0.0016 \text{ µF}$. * **Dielectric Material:** Metallized Polyester Film. * **Form Factor:** Usually a small, "dipped" radial package (often green or dark red). * **Operating Temperature:** Typically -40°C to +85°C. --- ### 3. Common Applications These capacitors are valued for their stability and small size. You will frequently find them in: 1. **Audio Circuits:** Used in tone controls and coupling because of their low distortion. 2. **Timing Circuits:** The ±5% (J) tolerance makes them reliable for oscillation and timing loops. 3. **Bypassing/Filtering:** Removing high-frequency noise from power lines in consumer electronics. 4. **Blocking:** Preventing DC current from passing while allowing AC signals through. --- ### 4.
