The **SH331M063ST** is a specific part number for an aluminum electrolytic capacitor manufactured by **Yageo (Aageo/Teapo)**. It is a general-purpose, radial-lead component commonly used in power supplies and audio circuits. --- ### ## Technical Specifications Below are the core technical parameters for the SH331M063ST: | Parameter | Value | | :--- | :--- | | **Capacitance** | 330 µF | | **Voltage Rating** | 63 VDC | | **Tolerance** | ±20% | | **Operating Temperature** | -40°C to +105°C | | **Lifetime (Endurance)** | 2,000 Hours @ 105°C | | **Mounting Type** | Through-Hole (Radial) | | **Case Size (D x L)** | 10mm x 15mm (Approx.) | | **Lead Spacing** | 5.0 mm | --- ### ### Part Number Breakdown Understanding the nomenclature helps in identifying equivalent parts: * **SH**: Series Name (Standard, 105°C high temperature). * **331**: Capacitance Code. The first two digits are significant figures, the third is the multiplier ($33 \times 10^1 = 330 \mu F$). * **M**: Tolerance code (M = ±20%). * **063**: Voltage rating (63 Volts). * **ST**: Packaging/Lead style (usually indicates bulk or specific lead forming). --- ### ### Key Features and Applications #### Features 1. **High Temperature Resistance:** Rated for 105°C, making it more durable than standard 85°C capacitors. 2. **Polarized:** As an electrolytic capacitor, it has a positive and negative terminal; reversing polarity will cause component failure. 3. **Compact Size:** The "SH" series is designed for high-density PCB mounting. #### Common Applications * **Smoothing:** Reducing ripple voltage in AC-to-DC power converters. * **Decoupling:** Filtering high-frequency noise in DC power rails. * **Energy Storage:** Providing short-term power for circuits during fluctuations. * **Audio:** Used in coupling or bypass stages of amplifiers. --- ### ### Usage Precautions ```cpp // Safety Check List for SH331M063ST 1. Polarity: Ensure the longer lead (+) is in the positive hole. 2. Voltage Margin: Do not exceed 63V; ideally, operate at 50V or lower for longevity. 3. Heat: Keep away from heat-generating components (heatsinks/transformers). ```
