The **HTK-35V561MIEBQ-R5** is a high-performance **Conductive Polymer Hybrid Aluminum Electrolytic Capacitor**. These components are widely used in automotive and industrial electronics due to their ability to combine the low ESR (Equivalent Series Resistance) of conductive polymers with the high voltage and safety features of traditional liquid electrolytes. --- ### 1. Technical Specifications Breakdown | Parameter | Value / Specification | | :--- | :--- | | **Series** | HTK (High Temperature, Low ESR) | | **Capacitance** | 560 µF | | **Voltage (Rated)** | 35V DC | | **Tolerance** | ±20% (M) | | **Operating Temperature** | -55°C to +125°C | | **Endurance** | 4,000 hours @ 125°C | | **Mounting Type** | Surface Mount (SMD) | | **Case Size (D x L)** | 10.0mm x 12.5mm | --- ### 2. Key Features and Technology #### Hybrid Electrolyte System This part uses a "Hybrid" design. It contains both a **conductive polymer** and a **liquid electrolyte**. * **Polymer Benefit:** Provides extremely low ESR, allowing the part to handle high ripple currents without overheating. * **Liquid Benefit:** Provides a "self-healing" mechanism for the dielectric layer, which increases reliability and prevents short circuits at high voltages. #### Automotive Grade Reliability The "BQ" suffix often indicates compliance with rigorous quality standards, such as **AEC-Q200**. This makes the capacitor suitable for: * Under-the-hood automotive applications. * Power management in Electric Vehicles (EVs). * High-vibration environments. --- ### 3.
