• Audio-grade Design Designed specifically for high-grade audio equipment with emphasis on high-fidelity sound quality as part of the LKG series.
• Capacitance & Rated Voltage 2.7 mF (2700 µF) nominal capacitance at a rated voltage of 25 V.
• Tolerance & Polarization ±20% capacitance tolerance at 120 Hz, 20°C; polarized device suitable for DC power applications.
• Ripple Current Rated ripple current of 2.15 A at 120 Hz to support audio power-supply filtering and transient loads.
• Operating Temperature & Endurance Specified operating range −40°C to +85°C with an endurance rating of 1000 hours at 85°C under rated voltage.
• Leakage and Stability Leakage current specified as not more than 3√(C·V) µA after 5 minutes at 20°C; endurance limits include capacitance change within ±20% and controlled tan δ increase after 1000 hours at 85°C.
• Environmental Compliance Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).
• Series Options The LKG series includes TYPE-I, TYPE-II and TYPE-III grading options in the family to address different tone-quality requirements in audio designs.

Typical Applications

• Professional audio amplifiers — Power-supply smoothing and reservoir capacitance to support clean, stable supply rails for high-fidelity amplification.
• High-fidelity consumer AV equipment — Decoupling and energy storage in receivers, integrated amplifiers, and other HD audio components.
• Studio and live sound gear — Bulk capacitance for mixers, preamps, and signal-chain power modules where sustained performance under audio loads is required.

Unique Advantages

• Audio-focused electrical design — Series and part-level design emphasize sound quality for high-grade and HD audio systems.
• Compact snap-in packaging — φ25 × 35 mm can with snap-in terminals for reliable mechanical mounting and straightforward assembly in audio chassis.
• High ripple capability — 2.15 A ripple current at 120 Hz supports demanding audio power-supply filtering and transient currents.
• Wide temperature and proven endurance — Rated for −40°C to +85°C and specified for 1000 hours at 85°C, providing predictable long-term behavior in thermal environments common to audio equipment.
• Predictable leakage and stability limits — Leakage current and endurance criteria are defined (leakage ≤ 3√CV µA after 5 minutes; endurance limits on capacitance and tan δ), aiding design margining and reliability planning.
• RoHS compliance — Meets contemporary environmental requirements for electronic assemblies.
