Technical Specifications | Parameter | Specification | |:---|:---| | **Manufacturer** | KYOCERA AVX | | **Capacitance** | 0.1 µF (100,000 pF) | | **Tolerance** | ±1% (F) | | **Voltage Rating (DC)** | 100 V | | **Dielectric Material** | C0G (NP0) | | **Termination/Leads** | Radial Leaded | | **Operating Temperature** | -55°C to +125°C | | **Packaging** | Tape & Reel (T/R) | --- ### 2. Part Number Breakdown (Nomenclature) To understand the specific properties of this component, we can deconstruct the part number: 1. **SR27**: Represents the series and physical size (SkyCap Radial Leaded). 2. **1**: Indicates the rated voltage (100V). 3. **A**: Signifies the Dielectric/Temperature Coefficient (C0G/NP0). 4. **104**: The capacitance code. The first two digits are significant (10), and the third is the multiplier (4 zeros), resulting in 100,000 pF or 0.1 µF. 5. **F**: Represents the tolerance level. "F" stands for **±1%**, which is exceptionally tight for a capacitor. 6. **A**: Standard termination (usually Tin/Lead or 100% Tin depending on the sub-series). 7. **R**: Packaging code (Tape and Reel). 8. **T**: Internal factory designation or specific lead spacing/length requirements. --- ### 3. Key Characteristics and Benefits * **C0G (NP0) Dielectric:** This is a "Class I" dielectric. It is highly stable and does not vary with temperature, voltage, or time. This makes it ideal for precision circuits. * **High Precision:** The ±1% tolerance ensures that the capacitance value remains extremely close to the nominal 0.1 µF, which is critical for timing, filtering, and resonant circuits. * **Radial Construction:** The leaded design (rather than Surface Mount/SMD) allows for easy manual assembly, prototyping on breadboards, or use in environments where through-hole mounting is preferred for mechanical strength. * **Conformal Coating:** The epoxy coating provides protection against moisture and environmental contaminants. --- ### 4. Common Applications * **Precision Filtering:** Used in signal processing to remove noise without distorting the signal. * **Timing Circuits:** Ideal for oscillators and clock circuits where stability over temperature is required. * **High-Q Applications:** Due to low losses (low Dissipation Factor) associated with C0G materials. * **Decoupling:** Filtering power supply lines in high-voltage or sensitive analog environments.
