Technical Specifications The following table outlines the typical electrical and physical characteristics of this series: | Parameter | Typical Value / Specification | | :--- | :--- | | **Component Type** | Thin Film Precision Chip Resistor | | **Resistance Tolerance** | ±0.1% to ±1.0% (Commonly high precision) | | **Power Rating** | 0.063W to 0.25W (Depends on case size) | | **Temperature Coefficient (TCR)** | ±10 ppm/°C to ±50 ppm/°C | | **Operating Temperature** | -55°C to +155°C | | **Termination Material** | RoHS compliant matte tin over nickel | --- ### 2. Key Electronic Features The "CC" and "R" designations in the part number usually refer to specific performance grades or packaging styles. * **Thin Film Technology:** Unlike thick film resistors, thin film (metal film) is deposited onto a ceramic substrate using sputtering. This results in much lower noise and better linearity. * **Stability:** These resistors maintain their value over long periods of time and under thermal stress, making them ideal for reference circuits. * **Low Parasitic Inductance:** Their compact surface-mount (SMD) design minimizes inductive effects, allowing them to perform well in high-frequency applications. --- ### 3. Common Applications Due to its precision nature, the KWDY-CC-R is typically used in the following areas: 1. **Medical Instrumentation:** For sensors that require exact voltage division or current sensing. 2. **Telecommunications:** In signal processing units where signal integrity is paramount. 3. **Automotive Electronics:** Used in Engine Control Units (ECUs) and battery management systems. 4. **Measuring Equipment:** Found in multimeters, oscilloscopes, and laboratory-grade power supplies. --- ### 4. Part Number Breakdown (Generic Structure) While specific manufacturers vary, the suffix codes generally mean: * **CC:** Often indicates a specific Temperature Coefficient (TCR) or a "Chip Component" designation. * **R:** Usually denotes "Reel" packaging (Tape & Reel) for automated pick-and-place assembly machines.
