The part number **RTZ-25V152MKHT-R5** refers to a specific **Aluminum Electrolytic Capacitor**. These components are widely used in power management and filtering applications due to their high capacitance-to-volume ratio. Below is a detailed breakdown of the electronic specifications and part number nomenclature based on standard industry coding for this series (typically associated with manufacturers like *Rubycon* or similar high-quality Japanese capacitor brands). ### 1. Technical Specifications | Parameter | Specification | Description | | :--- | :--- | :--- | | **Series** | RTZ | Low impedance, high reliability, and long life. | | **Capacitance** | 1500 µF | Indicated by "152" (15 x 10^2). | | **Rated Voltage** | 25V DC | The maximum continuous operating voltage. | | **Capacitance Tolerance** | ±20% | Indicated by "M". | | **Operating Temp.** | -40°C to +105°C | Designed for high-temperature stability. | | **Mounting Type** | Radial Lead | Through-hole mounting (THT). | --- ### 2. Part Number Breakdown To understand the specific physical and electrical characteristics, we can deconstruct the string: * **RTZ**: The **Series Name**. This series is usually optimized for **Low ESR** (Equivalent Series Resistance), making it ideal for switching power supplies. * **25V**: The **Rated Voltage**. Applying more than 25V may cause dielectric breakdown or leakage. * **152**: The **Capacitance Code**. * `15` = Significant digits. * `2` = Number of zeros. * Result: `1500 picofarads` in standard units, but for electrolytic capacitors, this is interpreted as **1500 µF**. * **M**: The **Tolerance Code**. M stands for ±20%, which is standard for electrolytic capacitors. * **KHT**: This typically refers to the **Case Size** and **Lead Configuration** (e.g., specific diameter x length, such as 10x20mm or 12.5x20mm). * **R5**: Refers to the **Packaging/Lead Processing**. Often indicates a specific lead pitch (e.g., 5.0mm) or Taped/Ammo pack for automated insertion. --- ### 3. Key Electronic Functions 1. **Filtering:** It smooths out ripples in DC voltage lines after rectification in AC/DC converters. 2. **Energy Storage:** It acts as a local reservoir of energy to support sudden spikes in current demand by the load. 3. **Bypassing:** It shunts high-frequency noise to the ground, protecting sensitive integrated circuits (ICs). 4. **Low ESR Importance:** Because this is an "RTZ" series (Low Impedance), it generates less heat internally when handling ripple current, leading to a longer lifespan in high-performance electronics. --- ### 4. Application Examples * Motherboards and computer peripherals. * LED Lighting drivers. * Industrial Power Supplies (SMPS). * Audio amplifiers (Power stage decoupling). ---
