The **2000-R5-RC** refers to a specific type of surface-mount electronic component, typically a **thick film chip resistor**. This nomenclature follows standard industry conventions for passive electronic parts. --- ### 1. Breakdown of the Part Number The alphanumeric code describes the physical size, electrical characteristics, and material composition of the component. | Segment | Meaning | Description | | :--- | :--- | :--- | | **2000** | Resistance Value | Usually represents **200 Ohms**. (Using the 3-digit code: 20 + 0 zeros). | | **R5** | Tolerance/Value | Often indicates a **0.5% tolerance** or acts as a decimal point ($0.5 \Omega$ depending on the vendor). | | **RC** | RoHS Compliant | Indicates the part is lead-free and meets environmental standards. | ### 2. Physical Specifications Most parts with this numbering belong to the **0805 or 1206** imperial sizing categories (though "2000" can sometimes refer to a custom series by manufacturers like Bourns or Ohmite). * **Mounting Type:** Surface Mount (SMD/SMT). * **Construction:** Thick film element on a ceramic substrate. * **Termination:** Tin (Sn) over Nickel (Ni) barrier to prevent leaching during soldering. ### 3. Electrical Characteristics These parts are designed for general-purpose circuitry. Typical specifications include: * **Power Rating:** Usually ranges from **1/10W to 1/4W** depending on the physical package size. * **Temperature Coefficient (TCR):** Typically $\pm 100ppm/^\circ C$ to $\pm 200ppm/^\circ C$. * **Operating Temperature:** Generally rated for $-55^\circ C$ to $+155^\circ C$. ### 4. Common Applications Because these are standard precision resistors, they are found in: 1. **Voltage Dividers:** Used to create specific reference voltages. 2. **Current Limiting:** Protecting LEDs or sensitive transistor bases. 3. **Pull-up/Pull-down Resistors:** Ensuring digital logic levels are defined. 4. **Feedback Loops:** Used in operational amplifier (Op-Amp) circuits. --- ### 5. Identification Example (Code Table) If the "2000" is a resistance code, it follows this logic: ```python # Resistance Calculation Logic def calculate_resistance(code): # For a 4-digit code like 2000 base = code[:3] # 200 multiplier = 10**int(code[3]) # 10^0 = 1 return int(base) * multiplier print(f"Resistance: {calculate_resistance('2000')} Ohms") # Output: Resistance: 200 Ohms ```
