The **CJP01-1003JB** is a specific electronic component, typically categorized as a **Chip Resistor** or a related passive component, often found in specialized industrial or consumer electronic circuits. Based on standard industry naming conventions (where "1003" often refers to resistance values or package sizes), here is a detailed breakdown of its electronic characteristics. --- ### 1. Component Specifications The following table outlines the technical parameters generally associated with this part number: | Parameter | Specification | Description | | :--- | :--- | :--- | | **Component Type** | Fixed Resistor | Passive surface-mount device (SMD) | | **Resistance Value** | 100 kΩ | "1003" code: 100 followed by 3 zeros | | **Tolerance** | ±5% (J) | Indicated by the "J" suffix | | **Package Size** | 0603 or 2512 | Depends on specific manufacturer series | | **Power Rating** | 1/16W to 1W | Varies based on package thermal dissipation | | **Temperature Coeff.** | ±100 to ±200 ppm/°C | Stability over temperature changes | --- ### 2. Breakdown of the Part Number To understand the electronic function, we can decompose the alphanumeric string: * **CJP01**: The manufacturer's series prefix. This often identifies the material composition (e.g., Thick Film) and the specific physical construction. * **1003**: The **Resistance Code**. * `100` = The significant digits. * `3` = The multiplier (10^3). * *Result:* 100,000 Ohms or **100 kΩ**. * **J**: The **Tolerance Code**. "J" represents a ±5% deviation from the nominal resistance. * **B**: Usually indicates the **Packaging Type**, such as Bulk or Tape & Reel. --- ### 3. Key Electronic Features * **Thick Film Technology**: Most resistors in this series use a metal glaze on a high-grade ceramic body, providing a balance between cost and performance. * **Surface Mount Design (SMD)**: These parts are designed for automated PCB assembly using SMT (Surface Mount Technology), which reduces parasitic inductance and capacitance. * **Durability**: Typically features a protective overcoat that is resistant to moisture and high temperatures. --- ### 4. Typical Applications The CJP01-1003JB is commonly used in circuits requiring standard impedance or pull-up/pull-down functions: 1. **Voltage Dividers**: Used in power management to scale down voltages for sensor inputs. 2. **Signal Conditioning**: Filtering noise in digital or analog communication lines. 3. **Current Limiting**: Protecting LEDs or small transistors from overcurrent. 4. **Pull-up/Pull-down Resistors**: Ensuring a stable logic state (High or Low) for microcontroller GPIO pins.
