The part number **HTK-35V561MIEE-R5** refers to a high-performance **Aluminum Electrolytic Capacitor**. Specifically, it belongs to the conductive polymer or hybrid technology category, often used in automotive and industrial applications where reliability and low ESR (Equivalent Series Resistance) are critical. --- ### 1. Technical Specifications Breakdown The part number typically follows a standardized coding system. Here is the technical breakdown: | Parameter | Specification | Description | | :--- | :--- | :--- | | **Series** | HTK | High temperature, long life, low ESR hybrid series. | | **Voltage (VDC)** | 35V | Rated working voltage (Surge voltage is usually higher). | | **Capacitance** | 561 (560µF) | "56" followed by "1" zero (560 microfarads). | | **Tolerance** | M | ±20% capacitance tolerance. | | **Case Size Code** | IEE | Represents physical dimensions (e.g., 10x10.2mm or 10x12.5mm). | | **Packaging** | R5 | Taping/Reel specification for automated SMT placement. | --- ### 2. Key Features and Technology #### Hybrid Construction This component is a **Conductive Polymer Hybrid Aluminum Electrolytic Capacitor**. It combines the benefits of two technologies: * **Electrolyte Liquid:** Provides "self-healing" properties for the dielectric layer. * **Conductive Polymer:** Ensures extremely low ESR and high ripple current capability. #### Core Performance Metrics * **Operating Temperature:** Typically rated for **-55°C to +125°C**. * **Low ESR:** Significantly lower resistance compared to standard liquid electrolytic capacitors, reducing heat generation. * **Longevity:** High endurance (often 4,000 hours at 125°C), which translates to decades of life at room temperature. * **Vibration Resistance:** The "R5" or "IEE" codes often imply an anti-vibration structure suitable for automotive engine environments. --- ### 3. Application Use Cases These parts are predominantly used in high-demand power electronics: 1. **Automotive ECU:** Power filtering for Engine Control Units or ADAS sensors. 2. **DC/DC Converters:** Smoothing output current in high-frequency switching power supplies. 3. **Industrial Robotics:** Providing stable power rails in environments with high ambient heat. 4. **LED Drivers:** Reducing flicker and managing heat in compact lighting modules. --- ### 4. Mounting & Footprint This is an **SMD (Surface Mount Device)** component. It features a "V-chip" vertical cylindrical shape with a flat square base for soldering onto PCBs. ```markdown Physical Characteristics: - Type: SMD (Surface Mount) - Lead Style: Gull-wing / Solder pads - Polarity: Polarized (Negative stripe on top of the can) ```
