LKG1V183MESBAK

The LKG1V183MESBAK is a snap‑in aluminum electrolytic capacitor from Nichicon’s LKG series, optimized for audio equipment applications. It combines high capacitance and robust low‑frequency ripple handling in a radial, snap‑in can package suited for power supply filtering and reservoir duties in high‑grade audio systems.

Designed for use across −40°C to +85°C with a rated voltage of 35 V and a capacitance of 18,000 µF (±20%), this component targets designers requiring large bulk energy storage and stable performance under typical audio system conditions.

Key Features

• High Capacitance — 18,000 µF (±20%) provides substantial energy reserve for power rails and smoothing in audio power supplies.
• Rated Voltage — 35 V rating suitable for common audio amplifier and preamplifier power rails.
• Low‑Frequency Ripple Handling — 4.3 A ripple current (120 Hz) to support demanding power supply ripple currents found in audio amplifiers.
• Loss Tangent (tan δ) — tanδ = 0.3 measured at 20°C, 120 Hz, enabling predictable loss characteristics in filter designs.
• Leakage Current — 2,380 µA (measured after rated voltage application), allowing designers to budget standby and bias currents.
• Endurance — Rated for 1,000 hours at 85°C with specified limits on capacitance change, tanδ, and leakage current after recovery to 20°C.
• Operating Temperature Range — −40°C to +85°C for broad environmental tolerance in consumer and professional audio equipment.
• Snap‑In Radial Package — φ30 × 50 mm (L: 5 × D: 3 cm) snap‑in can style for secure board mounting; supplied in tray packing for handling and assembly.
• Polarized — Designed for DC power applications where polarity is observed.
• RoHS Compliant — Conforms to applicable RoHS directives.

Typical Applications

• High‑Fidelity Audio Amplifiers — Bulk reservoir and smoothing for amplifier power rails to support transient current demands and reduce supply ripple.
• Audio Power Supplies — Filtering and energy storage in switchmode or linear supplies used in professional and consumer audio equipment.
• Preamp and Signal Chain Power — Stabilization and decoupling of DC rails feeding sensitive audio circuitry where large capacitance is required.

Unique Advantages

• Large Energy Reserve: 18,000 µF capacitance provides significant stored energy to support sustained and transient loads in audio systems.
• Robust Ripple Capability: 4.3 A ripple current rating at 120 Hz helps maintain low ripple under heavy supply loading typical of amplifier stages.
• Temperature and Endurance Rated: Specified for −40°C to +85°C operation and 1,000 hours endurance at 85°C, enabling predictable life performance in warm operating environments.
• Practical Mounting: Snap‑in radial can simplifies mechanical retention on PCBs and supports reliable assembly in tray packing.
• Predictable Loss and Leakage: Specified tanδ (0.3) and leakage current (2,380 µA) values allow straightforward power‑loss and standby current budgeting.
• RoHS Compliant: Meets environmental requirements for a wide range of commercial audio products.
