The part number **SH331M016ST** typically refers to an aluminum electrolytic capacitor manufactured by **Yageo/Teapo** (though other manufacturers use similar naming conventions). Below is a detailed breakdown of its specifications based on the alphanumeric code. --- ## 1. Part Number Breakdown The code follows a specific logic used by electronic component manufacturers: | Code Segment | Meaning | Specification | | :--- | :--- | :--- | | **SH** | Series Name | Standard High-Temperature Series (usually 105°C) | | **331** | Capacitance Value | **330 µF** (33 + one 0) | | **M** | Tolerance | **±20%** (Standard for electrolytic capacitors) | | **016** | Voltage Rating | **16 Volts (DC)** | | **ST** | Case/Packing | Typically indicates "Snap-in" or "Straight Lead" with specific Taping | --- ## 2. Technical Specifications This component is designed for general-purpose electronic filtering and power management. ### Electrical Characteristics * **Capacitance:** 330 Microfarads (µF). * **Voltage:** 16V DC (This is the maximum working voltage; it should typically be used in circuits of 12V or less). * **Temperature Rating:** Up to **105°C**. * **Polarity:** Polarized (Has a positive and negative lead; reversing voltage will cause failure). ### Physical Attributes * **Type:** Aluminum Electrolytic. * **Mounting:** Through-hole (Radial leads). * **Size:** Generally a small cylindrical "can" shape. --- ## 3. Common Applications Due to its 330µF / 16V rating, this part is frequently found in: 1. **Power Supply Filtering:** Smoothing out ripples in DC power lines. 2. **Audio Circuits:** Used for coupling or decoupling signals. 3. **Bypass Capacitors:** Stabilizing voltage near integrated circuits (ICs). 4. **Consumer Electronics:** Found in routers, chargers, and LED drivers. --- ## 4. Key Alternatives If you cannot find the exact Yageo part, you can look for these equivalents from other brands, provided the physical dimensions fit: * **Panasonic:** FC or FR Series (Higher quality/Lower ESR). * **Nichicon:** UPW or UHE Series. * **Rubycon:** YXF or ZL Series.
