Key value propositions include a high ripple current rating and industry‑grade endurance: designed for audio use with performance characteristics tuned for HD audio equipment and long operation at elevated temperatures.

Key Features

• Capacitance & Voltage — 3300 µF (3.3 mF) nominal capacitance with an 80 V rated voltage and capacitance tolerance of ±20% (‑20% to +20%).
• Audio‑Oriented Design — Part of the LKG series designed for high‑grade audio equipment; intended to support high fidelity sound quality in audio power and filtering circuits.
• Electrical Loss and Leakage — Tangent of loss angle (tanδ) specified at 0.25 (measured at 20°C, 120 Hz) and a measured leakage current of 1540 µA after voltage application, enabling predictable behavior in DC filtering and coupling.
• Ripple Current Capability — Low frequency ripple current rating of 3.15 A at 120 Hz, suitable for power supply smoothing and high‑current audio stages.
• Reliability & Endurance — Endurance rated for 1000 hours at 85°C (specifications met after restoration to 20°C), supporting sustained operation in elevated ambient temperatures.
• Operating Temperature Range — Specified for −40°C to +85°C operating environment.
• Package & Mounting — Snap‑in radial can package (φ30 × 40L) for secure mechanical retention; supplied in tray packing for board‑level handling.
• RoHS Compliance — Compliant with RoHS requirements.

Typical Applications

• Professional audio power supplies — Bulk smoothing and decoupling in amplifier and preamplifier power rails where 80 V rating and high ripple current are required.
• High‑fidelity amplifier stages — Energy storage and coupling in high‑grade audio circuits benefiting from the LKG series’ audio‑focused construction.
• Studio and broadcast equipment — Power reservoir and filtering capacitors for consoles, mixers, and other HD audio equipment operating within −40°C to +85°C.
• Audio filter networks — Low‑frequency filtering and crossover network support where stable capacitance and controlled tanδ are needed.

Unique Advantages

• Audio‑focused series engineering — LKG series design prioritizes sound quality, making the capacitor appropriate for HD audio equipment and high‑grade designs.
• High ripple handling — 3.15 A ripple current rating at 120 Hz reduces stress on power rails in demanding audio and power applications.
• Robust thermal endurance — Rated for 1000 hours at 85°C, supporting reliable operation in warm enclosures and sustained‑load conditions.
• Secure snap‑in mounting — Radial snap‑in can simplifies PCB mounting and mechanical retention for heavy or vibration‑exposed assemblies.
• Clear electrical characterization — Specified tanδ and measured leakage current enable predictable circuit design and easier validation in audio power systems.
• RoHS compliant — Meets environmental restrictions for lead‑free manufacturing processes.
