The part number **RTD-35V152MKHT-R5** refers to a high-performance **Aluminum Electrolytic Capacitor**. Below is a detailed breakdown of its electronic specifications and characteristics. --- ### 1. Technical Specifications | Parameter | Value / Description | | :--- | :--- | | **Capacitance** | 1,500 µF (Microfarads) | | **Voltage Rating** | 35V DC | | **Tolerance** | ±20% (Standard for electrolytic caps) | | **Temperature Range** | Typically up to +125°C or +150°C (RTD series is often high-temp) | | **Mounting Type** | Surface Mount Device (SMD) | | **Form Factor** | V-Chip / Cylindrical SMD | --- ### 2. Part Number Breakdown (Nippon Chemi-Con / United Chemi-Con Style) While specific codes can vary slightly by manufacturer, the nomenclature generally follows this logic: * **RTD**: Represents the **Series**. The RTD series is usually designed for automotive applications requiring high reliability, high temperature resistance, and vibration resistance. * **35V**: The maximum working voltage (35 Volts). * **152**: The capacitance code. The first two digits (15) are the significant figures, and the third (2) is the multiplier ($10^2$). Thus, $15 \times 100 = 1,500 \text{ µF}$. * **M**: The tolerance code ($M = \pm20\%$). * **KHT**: Typically refers to the case size and internal packaging technology (High-temperature sealing). * **R5**: Refers to the lead-free/RoHS compliance status and packaging format (e.g., Tape and Reel). --- ### 3. Key Features & Applications #### Features * **Low ESR:** Designed to handle high ripple currents with minimal internal heating. * **AEC-Q200 Qualified:** Most parts in the RTD series are automotive grade, meaning they have passed rigorous stress tests. * **Vibration Resistance:** The "R5" or "K" suffixes often denote anti-vibration structures (extra terminals or reinforced bases) to withstand high G-forces in engines. #### Common Applications 1. **Automotive ECU:** Power filtering for Engine Control Units. 2. **DC/DC Converters:** Smoothing output voltage in automotive power supplies. 3. **Industrial Controls:** High-temperature environments where standard capacitors would dry out and fail prematurely. --- ### 4. Comparison Table: Standard vs. RTD Series | Feature | Standard Electrolytic | RTD Series (RTD-35V152...) | | :--- | :--- | :--- | | **Max Temp** | 85°C or 105°C | 125°C to 150°C | | **Vibration** | Low tolerance | High (Anti-vibration base) | | **Lifespan** | ~2,000 hours | Up to 5,000+ hours at rated temp | ---
