LKG1K182MESBAK

The LKG1K182MESBAK from Nichicon is an aluminum electrolytic, snap‑in terminal capacitor in the LKG series configured for audio applications. It provides 1.8 mF (1800 µF) nominal capacitance at an 80 V rating with a polarized radial can and snap‑in mounting for secure board installation.

Designed for audio use within the LKG series, this part combines high capacitance and 80 V voltage capability with a low‑profile φ30 × 25 mm can size. RoHS compliant; tray packed. Note: this part is designated End of Life.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 µF) nominal capacitance with an 80 V rated voltage and ±20% tolerance for energy storage and smoothing in higher‑headroom audio circuits.
• Audio‑Oriented Series Design — Part of Nichicon’s LKG series specified “For Audio Use,” developed to prioritize sound quality for audio equipment applications.
• Loss & Ripple Characteristics — Specified tangent of loss angle (tan δ) of 0.25 and an LF ripple current rating of 2.4 A at 120 Hz to support AC ripple handling and stable performance under audio power conditions.
• Leakage Current — Listed leakage current of 1130 µA, providing a measurable baseline for bias and standby current planning.
• Thermal & Endurance — Rated operating range from −40°C to +85°C with an endurance specification of 1000 hours at 85°C, enabling predictable lifetime behavior under elevated temperature stress.
• Package & Mounting — Radial, can type with snap‑in terminals (φ30 × 25 mm), provided in tray packing for board assembly.
• Compliance — RoHS compliant as stated in the product data.

Typical Applications

• Professional and Consumer Audio Power Supplies — Bulk energy storage and smoothing for amplifier rails and audio power circuits where 80 V rating and 1.8 mF capacitance are required.
• Audio Signal Conditioning — Decoupling and filtering in audio equipment to support stable DC rails and reduce supply ripple that can affect audio fidelity.
• Loudspeaker Crossover and Filter Networks — Use in passive or active crossover networks where high capacitance and stable performance under audio‑grade demands are needed.

Unique Advantages

• High Voltage Headroom — 80 V rating allows use in higher‑voltage audio supply sections compared with lower‑voltage electrolytics.
• Substantial Capacitance in a Compact Can — 1.8 mF in a φ30 × 25 mm package offers significant energy storage while conserving board area.
• Audio‑Focused Series Engineering — LKG series design intent for audio use supports selection for high‑fidelity equipment designs.
• Defined Ripple and Loss Metrics — Specified 2.4 A ripple at 120 Hz and tan δ of 0.25 provide quantifiable parameters for thermal and ripple budgeting in power designs.
• RoHS Compliant — Conforms to RoHS requirements for materials compliance.
• Snap‑In Mounting — Radial snap‑in terminals simplify mechanical retention on PCBs and are suited to through‑hole assembly methods.
