Key Features

• Capacitance & Voltage — 1200 µF nominal capacitance with a 35 V rated voltage and ±20% tolerance at 20°C, 120 Hz.
• Audio-focused Grade — Part of the LKG series and identified as TYPE-III (Super Through), optimized for high-tone quality in audio applications.
• Electrical Performance — Specified tangent of loss angle (tan δ) of 0.22 (measured at 20°C, 120 Hz), low-frequency ripple current capability of 1.45 A at 120 Hz, and a leakage current specified at 610 µA.
• Endurance & Temperature Range — Rated life of 1000 hours at 85°C with an operating temperature range of −40°C to +85°C.
• Construction & Termination — Snap-in terminal (radial can, snap-in package) for secure mounting; TYPE-III grade features low-drag gold-plated terminal adoption as described for the LKG series.
• Physical & Packaging — Compact size φ22 × 30 mm (L: 3 cm × D: 2.2 cm), supplied in tray packing for production handling.
• Compliance — RoHS-compliant construction in accordance with the LKG series specifications.

Typical Applications

• High-Fidelity Amplifiers — Energy reservoir and power-supply stabilization in premium audio amplifiers where tone quality is a priority.
• Studio and Professional Audio Equipment — Power filtering and decoupling in studio-grade preamplifiers, mixers, and signal-processing racks that demand consistent audio performance.
• High-End Consumer Audio — Power-supply smoothing and transient support in high-grade consumer audio products targeting improved acoustic fidelity.

Unique Advantages

• Audio-Optimized Construction: LKG series TYPE-III (Super Through) design emphasizes high-tone quality and sound fidelity for HD audio equipment.
