The part number **M5RJ83RQJ-R** refers to a high-precision, surface-mount (SMD) thick film chip resistor, typically manufactured by companies like **KOA Speer** or **Rohm** (following standard industry naming conventions for MCR/RM series). Below is a detailed breakdown of its electronic specifications and characteristics. --- ### 1. Specification Table | Parameter | Specification | Description | | :--- | :--- | :--- | | **Component Type** | Thick Film Chip Resistor | Standard SMD resistor | | **Resistance Value** | 8.3 MΩ (8.3 Megohms) | Determined by the code "83R" or "835" | | **Tolerance** | ±5% (J) | Allowable variance from nominal value | | **Package Size** | 0603 (Metric 1608) | Dimensions: 1.6mm x 0.8mm | | **Power Rating** | 0.1W (1/10 Watt) | Maximum power dissipation at 70°C | | **Voltage Rating** | 50V - 75V | Maximum working voltage | | **Operating Temp** | -55°C to +155°C | Industrial temperature range | | **Packaging** | Taped & Reeled (R) | Supplied on a 7-inch reel for pick-and-place | --- ### 2. Part Number Deciphering The alphanumeric string follows a standard manufacturer coding logic: * **M5R**: Series prefix, often denoting the "MCR" or "RM" series (Thick film, general purpose). * **J**: Tolerance code. `J` represents **±5%**. (F = 1%, G = 2%, K = 10%). * **83R / 835**: The resistance value. In many coding systems, the first two digits are significant figures and the third is the multiplier (83 x 10^5 ohms = 8.3 MΩ). * **Q**: Size code (In this specific series, Q often corresponds to the **0603** EIA footprint). * **J**: Termination material (usually Lead-Free/Sn). * **-R**: Packaging suffix, standing for **Reel** (Taping). --- ### 3. Application and Usage Because this is a high-resistance value (8.3 MΩ) component, it is commonly used in specific electronic scenarios: * **Voltage Dividers:** Used in high-impedance circuits to scale down high voltages for sensing. * **Pull-up/Pull-down Resistors:** Used in low-power CMOS circuits where minimal current leakage is required. * **RC Timing Circuits:** Used in conjunction with capacitors to create long time constants. * **Feedback Loops:** Frequently found in operational amplifier (Op-Amp) circuits to control gain. --- ### 4. Typical Footprint (0603) If you are designing a PCB (Printed Circuit Board) for this part, use the following dimensions: ```text Land Pattern Dimensions (mm): L (Length): 1.60 ± 0.10 W (Width): 0.80 ± 0.10 H (Height): 0.45 ± 0.10 ```
