This part delivers a combination of high capacitance, a 2.45 A low-frequency ripple current rating (120 Hz), and a compact φ35 × 20 mm package. Product status: End Of Life.

Key Features

• Capacitance & Voltage — 1800 µF nominal capacitance at a rated voltage of 63 V, with a tolerance of ±20% (–20% to +20%).
• Audio-Focused Design — Series-level design intent for high-grade audio equipment aimed at prioritizing high-fidelity sound quality.
• Ripple Handling — Low-frequency ripple current rating of 2.45 A at 120 Hz, suitable for power-smoothing roles in audio circuits.
• Electrical Characteristics — Dissipation factor (tan δ) of 0.3 measured at 20°C, 120 Hz, and a measured leakage current of 1010 µA after standard application conditions.
• Endurance & Temperature Range — Rated lifetime of 1000 hours at 85°C and specified operating temperature range of −40°C to +85°C.
• Package & Mounting — Snap-in radial can (φ35 × 20 mm) for secure chassis or chassis-submount installation and tray packing for handling.
• RoHS Compliant — Conforms to applicable RoHS directive requirements as indicated for the series.

Typical Applications

• High‑grade audio amplifiers — Bulk and smoothing capacitance where high capacitance at 63 V and robust ripple handling support stable audio power rails.
• Professional audio consoles and mixers — Energy storage and decoupling to help maintain low-noise supplies for sensitive audio circuitry.
• Audio power supply filtering — Use as reservoir and filter capacitors in power supply stages to support consistent performance under varying load conditions.

Unique Advantages

• High capacitance in a compact can — 1800 µF in a φ35 × 20 mm snap-in package provides significant energy storage while minimizing space impact.
• Audio-oriented series design — Part of the LKG series, which is specified for high-fidelity audio use, aligning component selection with audio performance goals.
• Designed for ripple-heavy environments — 2.45 A ripple current rating at 120 Hz supports filtering and smoothing in demanding supply conditions common in audio equipment.
• Temperature and endurance specification — 1000-hour endurance at 85°C and an operating range of −40°C to +85°C provide predictable behavior over typical audio equipment thermal envelopes.
• Clear electrical parameters — Specified tan δ and leakage current figures allow engineers to account for loss and bias behavior during system design.
