• Audio-Grade Construction — LKG series, TYPE-I (Gold Tune) grade tuned for high-grade audio equipment and high-fidelity sound priorities as indicated in the LKG series documentation.
• Electrical Performance — Specified tangent of loss angle (tan δ) of 0.57 and a measured leakage current of 2,170 µA; ripple current rating of 3.65 A at 120 Hz.
• Mounting & Package — Snap-in terminal, radial can package (φ35 × 35L) designed for secure PCB assembly; tray packing.
• Reliability & Life — Endurance rated to 1,000 hours at 85°C with specified limits on capacitance change, tan δ, and leakage current after the test period.
• Operating Environment — Rated for operation from −40°C to +85°C; RoHS compliant.

Typical Applications

• High-fidelity Audio Equipment — Bulk energy storage and smoothing for power supplies in audio amplifiers and preamplifiers where large capacitance and audio-focused component selection are required.
• Power Supply Reservoirs — Main or auxiliary reservoir capacitor for low-frequency ripple filtering at 120 Hz in linear and discrete power supply designs.
• Signal Processing Systems — Energy buffering for audio signal processing racks and studio equipment that demand stable capacitance and specified endurance at elevated temperatures.

Unique Advantages

• Large Energy Storage: 33,000 µF capacitance at 16 V provides significant reservoir capability to stabilize low-frequency power rails.
