The part number **1M5M5N-R** refers to a specific type of **SMD (Surface Mount Device) Multilayer Ceramic Chip Capacitor (MLCC)**, typically produced by manufacturers like Walsin Technology or similar vendors following industry-standard naming conventions. Below is a detailed breakdown of the technical specifications and characteristics of this electronic component. ### 1. Part Number Deciphering Based on standard MLCC nomenclature, the alphanumeric code represents the following attributes: | Segment | Feature | Description | | :--- | :--- | :--- | | **1M** | Series/Brand | Often denotes a specific series or low-profile MLCC line. | | **5M** | Capacitance | Usually represents a specific capacitance value (e.g., 5.0 pF or a multiplier). | | **5N** | Tolerance/Voltage | "5" often relates to a 50V rating; "N" refers to tolerance (±0.5pF or specific %). | | **-R** | RoHS Compliance | Indicates the part is Lead-Free and compliant with environmental regulations. | --- ### 2. General Technical Specifications MLCCs like the 1M5M5N-R are essential for managing electrical signals within a circuit. Their general properties include: * **Capacitance Value:** Precise value depends on the manufacturer's specific datasheet (commonly in the pF or nF range). * **Voltage Rating:** Typically **50V DC**, making it suitable for standard consumer electronics. * **Dielectric Material:** Usually **NPO (C0G)** or **X7R**. NPO is highly stable across temperature changes, while X7R offers higher capacitance in smaller sizes. * **Package Size:** Standard SMD sizes (e.g., 0402, 0603, or 0805). --- ### 3. Applications These capacitors are utilized in almost every modern electronic assembly due to their reliability and small footprint. * **Filtering:** Removing noise from power supply lines. * **Bypassing:** Providing a local energy reservoir for integrated circuits (ICs). * **Decoupling:** Preventing high-frequency noise from spreading through the PCB. * **Tuning:** Used in RF (Radio Frequency) circuits for frequency selection. --- ### 4. Handling and Soldering | Aspect | Requirement | | :--- | :--- | | **Soldering Method** | Reflow or Wave soldering. | | **Sensitivity** | Highly sensitive to mechanical stress (cracking). | | **Storage** | Should be kept in original moisture-barrier packaging to prevent oxidation of terminals. | ---
