The part number **SH331M010ST** refers to a specific type of **Aluminum Electrolytic Capacitor**. This component is commonly used in power supplies, audio equipment, and general consumer electronics for energy storage and noise filtering. Below is a detailed breakdown of its electronic specifications and characteristics. --- ### 1. Specification Overview The part number follows a standard coding convention used by manufacturers like **Yageo (Yageo/Teapo)** or **Cornel Dubilier (CDE)**. | Parameter | Specification | Description | | :--- | :--- | :--- | | **Capacitance** | 330 µF | The amount of charge the capacitor can store. | | **Voltage Rating** | 10 VDC | The maximum continuous DC voltage it can handle. | | **Tolerance** | ±20% | The allowable variance in capacitance (M code). | | **Temperature** | -40°C to +105°C | Operating temperature range (SH series). | | **Life Span** | ~2000 Hours | Expected endurance at its maximum temperature. | | **Mounting Type** | Through-Hole | Radial lead configuration (plugs into a PCB). | --- ### 2. Breakdown of the Part Number Decoding the alphanumeric string reveals the component's physical and electrical properties: * **SH**: Series prefix (indicates Standard 105°C high-temperature series). * **331**: Capacitance code. The first two digits (33) are the value, and the third (1) is the multiplier ($10^1$). $33 \times 10 = 330$ µF. * **M**: Tolerance code. M stands for ±20%. * **010**: Rated Voltage. 010 represents 10 Volts. * **ST**: Packaging/Lead style. Often stands for Standard Taping or Straight leads. --- ### 3. Key Electronic Characteristics #### A. Polarity This is a **polarized** component. It has a specific positive (+) and negative (-) terminal. Installing it backward can lead to gas buildup, leakage, or explosion of the aluminum can. #### B. Equivalent Series Resistance (ESR) As an electrolytic capacitor, it has an internal resistance. While the SH series is a standard series, it is designed to filter ripple current in low-voltage circuits. #### C. Applications * **Decoupling:** Placing it near an IC to provide a steady voltage. * **Filtering:** Removing AC ripple from a DC power supply output. * **Energy Storage:** Providing short bursts of power during load spikes. --- ### 4. Physical Dimensions (Typical) For a 330µF/10V capacitor, the physical footprint is usually quite small: * **Diameter:** ~6.3 mm * **Height:** ~11 mm * **Lead Spacing:** ~2.5 mm ---
