The **KCK-15-R/Q** typically refers to a high-voltage, disc-style ceramic capacitor often used in specialized industrial, medical, or broadcast equipment. These components are designed for high stability and reliability under high-tension loads. --- ### 1. Technical Specifications While exact specifications can vary by manufacturer (often associated with brands like Murata or specialized Chinese high-voltage component makers), the general parameters for this series are as follows: | Parameter | Specification (Typical) | | :--- | :--- | | **Capacitance Range** | 100pF to 4700pF | | **Voltage Rating** | 10kV to 15kV DC | | **Tolerance** | ±10% (K) or ±20% (M) | | **Temperature Coefficient** | N4700, Y5P, or Y5U | | **Dielectric Material** | Ceramic (Class II) | | **Termination** | Radial Lead (Through-hole) | --- ### 2. Physical Construction The part is engineered to handle extreme electrical stress through a specific physical design: * **Disc Shape:** A circular ceramic body that maximizes surface area while maintaining a compact footprint. * **Encapsulation:** Coated in high-grade epoxy resin (usually blue or maroon) to prevent "arcing" (electrical discharge through the air) between the leads. * **Lead Spacing:** Wider spacing (pitch) between the pins to satisfy creepage and clearance safety standards for high-voltage circuits. --- ### 3. Key Applications Because of its high voltage tolerance, the KCK-15-R/Q is commonly found in: 1. **X-Ray Machines:** Used in the voltage multiplier circuits of medical imaging equipment. 2. **Laser Power Supplies:** Handling the high-energy pulses required for gas or solid-state lasers. 3. **Electrostatic Spraying:** Providing stable high voltage for paint or powder coating systems. 4. **CRT Monitors/TVs:** Historical use in the flyback transformer and focus circuits. --- ### 4. Comparison Table: R vs. Q Suffixes In electronic part numbering, suffixes often denote specific variations: | Suffix | Meaning | | :--- | :--- | | **-R** | Often indicates **RoHS Compliance** (Lead-free) or specific taping for radial auto-insertion. | | **-Q** | Usually signifies **Automotive Grade** or a specific **Quality/Reliability** standard (e.g., AEC-Q200). | --- ### 5. Selection Considerations When replacing or designing with this part, keep the following in mind: * **Temperature Coefficient:** An "N4700" dielectric is much more stable than "Y5U" for high-frequency or timing-sensitive applications. * **Voltage Derating:** It is best practice to run these at 50-70% of their rated voltage for maximum longevity.
