LKG1J821MESABK

The LKG1J821MESABK is an LKG series snap‑in aluminum electrolytic capacitor from Nichicon, optimized for audio equipment. It is a TYPE‑II grade snap‑in radial can designed with audio performance in mind and intended for use in high‑grade audio systems.

Key specifications include 820 µF capacitance at ±20% tolerance, a 63 V rated voltage, low‑frequency ripple current rating of 1.65 A (120 Hz), and an operating temperature range of −40 °C to +85 °C. Status: End Of Life.

Key Features

• Audio‑oriented LKG Series (TYPE‑II) TYPE‑II grade from the LKG series—specified in the series documentation as the center grade intended to provide improved sound characteristics for audio applications.
• Capacitance and Tolerance 820 µF nominal capacitance with a tolerance of −20% to +20% (measured at 120 Hz, 20 °C), supporting bulk energy storage and low‑frequency coupling requirements.
• Voltage Rating 63 V rated voltage for applications requiring higher DC headroom.
• Low‑Frequency Ripple Handling Rated low‑frequency ripple current of 1.65 A at 120 Hz, suitable for filtering and smoothing at line‑frequency ripple conditions.
• Dissipation and Leakage tan δ (dissipation factor) of 0.3 (measured at 20 °C, 120 Hz) and a typical leakage current of 680 µA, specified for predictable circuit behavior.
• Endurance and Temperature Range Rated for 1000 hours at 85 °C and specified to operate from −40 °C to +85 °C, supporting sustained operation in elevated ambient temperatures.
• Mechanical Package Snap‑in, radial can package (φ25 × 20 mm) designed for secure PCB mounting and straightforward assembly; supplied in tray packing.
• Regulatory Compliance RoHS compliant as indicated in the product data.

Typical Applications

• High‑grade Audio Equipment Intended for use in premium audio systems where component selection is tuned for sound quality.
• HD Audio Systems Suited to devices and modules targeting high‑definition audio performance as highlighted in the LKG series documentation.
• Audio Power Modules Applicable where robust bulk capacitance and ripple handling at 120 Hz are required for audio power supply filtering.

Unique Advantages

• Audio‑Focused Design: Part of the LKG series and specified as TYPE‑II, aligning the capacitor’s characteristics with audio fidelity considerations described in the series literature.
• High Voltage Capability: 63 V rating provides additional design margin where higher DC voltages are present.
• Reliable Endurance: 1000‑hour endurance at 85 °C gives predictable lifetime behavior for elevated‑temperature applications.
• Effective Ripple Performance: 1.65 A ripple current rating at 120 Hz supports line‑frequency filtering needs common in audio power stages.
• Robust Mounting: Snap‑in radial can package simplifies board attachment for larger electrolytic capacitor placements and system assembly.
• Regulatory Conformance: RoHS compliance for materials and processes as stated in the product data.
