Technical Specifications | Parameter | Specification | | :--- | :--- | | **Capacitance** | 330 µF (Microfarads) | | **Voltage Rating** | 200 VDC | | **Tolerance** | ±20% | | **Operating Temperature** | -40°C to +105°C | | **Lifetime** | 3,000 Hours @ 105°C | | **Termination Style** | Snap-In (2 Pins) | | **Case Size** | 25mm Diameter x 30mm Length | --- ### 2. Breakdown of the Part Number The alphanumeric code follows a specific naming convention used by Cornell Dubilier: * **SLP**: Series Name (105°C Snap-In Aluminum Electrolytic). * **331**: Capacitance Code. The first two digits (33) are the significant figures, and the third (1) is the multiplier ($10^1$). $33 \times 10 = 330$ µF. * **M**: Tolerance ($M = \pm 20\%$). * **200**: DC Voltage Rating (200 Volts). * **C3**: Case Code. Refers to the physical dimensions (25mm x 30mm). * **P3**: Terminal Style (Standard 2-pin snap-in). --- ### 3. Key Electronic Characteristics #### A. Snap-In Terminals The "Snap-In" design is engineered to hold the component securely in place on a Printed Circuit Board (PCB) during the soldering process. This is vital for larger, heavier capacitors to prevent movement that could break solder joints. #### B. 105°C Temperature Rating Unlike standard 85°C capacitors, the SLP series is rated for 105°C. This makes it suitable for high-heat environments like power supplies, where heat dissipation from transformers and semiconductors is significant. #### C. High Ripple Current Handling This part is designed to handle high AC ripple currents, which are common in the rectification stages of power converters. It smooths the "pulsing" DC into a steady voltage. --- ### 4. Common Applications * **Switch Mode Power Supplies (SMPS):** Used for input filtering and bulk energy storage. * **Motor Drives:** Provides the DC bus voltage stabilization. * **Welding Equipment:** High energy discharge and filtering. * **Uninterruptible Power Supplies (UPS):** Energy reservoirs during power transitions.
