LKG1J681MESBCK

The LKG1J681MESBCK is a Nichicon LKG series snap‑in aluminum electrolytic capacitor specified at 680 µF and 63 V. It is a polarized, radial snap‑in can designed for audio equipment use, offering a compact φ30 × 20 mm package with tray packing.

Engineered for audio applications, the part combines a 1.9 A low‑frequency ripple capability, measured tangent of loss angle (tanδ) of 0.22 (20°C, 120 Hz), and a 1000 hour endurance at 85°C for stable performance in high‑fidelity audio power supplies and related circuits.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a rated voltage of 63 V and a tolerance of ±20% (‑20% to +20%).
• Audio‑oriented design — Part of the LKG series specified "For Audio Use" with series features aimed at high‑grade audio equipment.
• Loss characteristics — Tangent of loss angle (tanδ) specified at 0.22 when measured at 20°C, 120 Hz, supporting predictable dissipation in audio circuits.
• Ripple handling — Low frequency ripple current rated at 1.9 A (at 120 Hz), suitable for smoothing and decoupling in audio power rails.
• Leakage and endurance — Specified leakage current of 620 µA and endurance of 1000 hours at 85°C under rated voltage conditions.
• Temperature stability — Operating range from ‑40°C to 85°C; series impedance behavior at low temperature is specified (Z(‑25°C)/Z(+20°C) ≤ 4, Z(‑40°C)/Z(+20°C) ≤ 12).
• Package & mounting — Snap‑in radial can, compact size φ30 × 20 mm, supplied in tray packing for efficient handling.
• Compliance — RoHS‑compliant material status.

Typical Applications

• High‑fidelity audio power supplies — Bulk smoothing and reservoir capacitance where stable ripple handling and long endurance are required.
• Amplifier rails — Decoupling and energy storage for discrete and integrated audio amplifier circuits.
• Professional audio equipment — Used in mixers, preamps, and other audio systems that prioritize tonal fidelity and stable supply filtering.

Unique Advantages

• Audio‑focused specification — Part of a series explicitly designed "For Audio Use," aligning component choice with high‑fidelity design goals.
• Measured dissipation — Specified tanδ at 20°C/120 Hz provides a verifiable parameter for estimating internal losses in audio circuit design.
• Robust ripple capability — 1.9 A ripple rating at 120 Hz supports demanding smoothing tasks on audio power rails.
• Compact snap‑in form — φ30 × 20 mm snap‑in can provides a space‑efficient radial mounting option for chassis and PCB assemblies.
• Elevated temperature endurance — 1000 hours at 85°C under rated voltage offers a defined long‑term operating window for thermal stress planning.
• Traceable marking — Series marking is printed in gold on a black sleeve for clear identification during assembly and inventory.
