Series Core Advantages

• Dielectric Performance: Polycarbonate material ensures constant capacitance with temperature changes and high insulation resistance.
• Electrical Traits: Low ESR (Equivalent Series Resistance) due to metal foil electrodes and end-surface contacts, ideal for pulse applications.
• Environmental Compliance: RoHS-compliant, meeting EU environmental standards.

2. Mechanical Dimensions & Physical Attributes

All dimensions are derived from WIMA FKC 3 series standard specifications (units: mm) and aligned with the 6800 pF / 160 VDC / 10 mm PCM configuration:

4. Mandatory & Complementary Accessories

4.1 Essential Mounting & Assembly Accessories (User-Supplied)

• PCB Layout Compatibility: Requires PCB land pattern matching 10 mm lead spacing (PCM=10 mm); recommended pad size: 1.2 mm × 2.0 mm for secure soldering.
• Soldering Materials: Lead-free or tin-lead solder (e.g., Sn63/Pb37) with melting point 183°C–217°C; avoid exceeding 260°C for ≤10 seconds to prevent lead damage.
• Insulation Sleeves (Optional): Heat-shrink tubing (1.5–2.0 mm inner diameter) for lead insulation in high-density PCB layouts; compatible with capacitor body dimensions (4×13 mm).

4.2 Recommended Complementary Components

• Decoupling Resistors: 10 kΩ carbon film resistors (optional) for surge current protection in high-pulse circuits.
• ESD Protection: ESD suppressors (e.g., 0402-sized TVS diodes) in parallel with the capacitor for electrostatic discharge protection during assembly and operation.
• Mounting Clips (Optional): Plastic capacitor clips (for 4 mm width bodies) to secure the component in vibration-prone applications (e.g., industrial machinery).

5. Packaging & Handling Accessories

5.1 Standard Factory Packaging

• Bulk Packaging: Anti-static plastic tubes (default for small-to-medium volume orders) to prevent ESD damage and physical scratches during storage/transport.
• Labeling: Each tube includes product model, capacitance, voltage rating, tolerance, and batch traceability code.
• Tape & Reel Option: Available for high-volume automated SMT assembly (contact WIMA for customization); compliant with EIA-481 standards.

5.2 Handling & Storage Accessories (User-Required)

• ESD Protection: ESD-safe workstation, wrist straps, and tweezers mandatory during handling (polycarbonate dielectric is sensitive to electrostatic discharge).
• Storage Conditions: Store in sealed anti-static bags with desiccants; ambient temperature: -20°C to +40°C, relative humidity: 15%–75% (non-condensing) to prevent moisture absorption.
• Shelf Life: 2 years from manufacturing date when stored per WIMA guidelines; re-inspect capacitance and insulation resistance if stored beyond shelf life.

6. Application-Specific Compatibility Accessories

6.1 Target Application Scenarios

Optimized for high-frequency switching circuits, pulse-width modulation (PWM) systems, and high-dv/dt environments, including:

• High-speed digital circuit decoupling.
• Switch-mode power supply (SMPS) filter circuits.
• RF communication equipment (resonant frequency applications).
• Industrial control systems (PLCs, inverters).

6.2 Compatible System Requirements

• PCB Design: Separate power and signal planes to minimize crosstalk; maintain ≥2 mm clearance from high-temperature components (e.g., resistors, diodes) to avoid dielectric degradation.
• Voltage Derating: Recommend 20% voltage derating for long-term reliability (e.g., use at ≤128 VDC for 160 VDC rating).
• Frequency Limitation: AC operation limited to ≤400 Hz; consult WIMA for derating guidelines at higher frequencies.

8. Key Notes & Accessories Compatibility

1. Lead Spacing Criticality: LS10 (10 mm PCM) is fixed; alternative lead spacings (7.5 mm, 15 mm) are available via model variations (e.g., LS7.5, LS15) but require PCB layout adjustments.
2. No Proprietary Accessories: All mounting, soldering, and protection accessories are industry-standard; no WIMA-exclusive components required.
3. Tolerance Compatibility: ±5% tolerance suits precision applications; for lower tolerance (±10%), refer to model FKC3 6800/160/10 LS10.
4. Toped Version: A sealed "toped" variant (for enhanced moisture resistance) is available; specify "toped" when ordering (see WIMA FKC 3 datasheet page 92).
5. Replacement Compatibility: Directly interchangeable with other FKC 3 series capacitors of the same capacitance, voltage, and lead spacing (e.g., FKC3 6800/160/5 PCM10).
