The part number **RTT-80V101MJHT-R5** corresponds to a specific surface-mount Aluminum Electrolytic Capacitor. Based on standard industry nomenclature (likely from manufacturers like **United Chemi-Con** or **Samxon**), here is the detailed breakdown of its specifications and characteristics. ### 1. Specification Overview | Parameter | Value | Details | | :--- | :--- | :--- | | **Component Type** | Capacitor | Aluminum Electrolytic (SMD Type) | | **Capacitance** | 100 µF (101) | Measured in microfarads | | **Voltage Rating** | 80V | Maximum DC working voltage | | **Tolerance** | ±20% (M) | Standard industry tolerance | | **Temperature Range** | -55°C to +105°C | High-temperature reliability | | **Package/Case** | V-Chip (SMD) | Surface mount vertical cylinder | | **Packaging** | Tape & Reel (R5) | 13" or 15" reel for automated pick-and-place | --- ### 2. Deep Dive into Part Number Logic The alphanumeric string can be broken down to understand the component's physical and electrical properties: * **RTT**: Series prefix (typically denotes high reliability, low impedance, or long life depending on the specific manufacturer's catalog). * **80V**: **Rated Voltage.** 80 Volts is a common rating for automotive and industrial power supplies. * **101**: **Capacitance Code.** The first two digits (10) are the significant figures, and the third (1) is the multiplier ($10 \times 10^1 = 100$ µF). * **M**: **Tolerance Code.** M represents ±20%. * **JHT**: **Size and Series Suffix.** This usually refers to the specific case dimensions (e.g., 10mm x 10.2mm) and the specific chemical electrolyte formulation used. * **R5**: **Packaging Code.** Denotes the quantity and reel size for the tape-and-reel delivery system. --- ### 3. Key Applications Because of the 80V rating and 105°C temperature tolerance, these capacitors are typically found in: 1. **Automotive Electronics:** Used in 48V mild-hybrid systems or 24V truck electrical systems where voltage spikes are common. 2. **Industrial Power Supplies:** Filtering and smoothing in DC-DC converters. 3. **LED Lighting Drivers:** Providing long-life stability in high-heat environments. 4. **Telecommunications:** Power line filtering for base stations. --- ### 4. Mounting and Handling As an **SMD (Surface Mount Device)**, this part is designed for **Reflow Soldering**. Care must be taken regarding: * **Polarity:** Aluminum electrolytic capacitors are polarized. Incorrect orientation will lead to component failure or explosion. * **Shelf Life:** Electrolytic capacitors have a shelf life; if stored for years without voltage applied, the oxide layer may degrade.
