LKG1C103MESZBK

The Nichicon LKG1C103MESZBK is an aluminum electrolytic, snap-in terminal capacitor designed for audio equipment. It delivers 10,000 µF capacitance at a 16 V rating with a ±20% tolerance, targeted toward power-supply smoothing and filtering in high-fidelity audio designs.

The part is supplied in a radial snap-in can (φ22 × 40 mm) with tray packing. Key performance attributes include a 2.65 A ripple‑current rating at 120 Hz, a loss tangent (tan δ) of 0.35, a rated operating range of −40°C to +85°C and an endurance of 1,000 hours at 85°C. Product status: End of Life.

Key Features

• Capacitance & Voltage — 10,000 µF nominal capacitance rated at 16 V with ±20% tolerance for bulk energy storage and low-frequency smoothing.
• Audio‑Grade Construction (TYPE‑II) — Designation BK in the LKG series indicates the TYPE‑II center grade optimized for audio applications with electrode foil tuned for sound quality and multiple-use scenarios.
• Low‑frequency loss (tan δ) — tan δ = 0.35 (measured per series specification at 120 Hz, 20°C), supporting acceptable dissipation characteristics for audio power stages.
• Ripple Current — Rated ripple current 2.65 A at 120 Hz, enabling robust handling of power-supply ripple in amplifier and filter circuits.
• Leakage Current — Specified leakage current consistent with the LKG series (product description lists 1,200 µA), suitable for typical audio power supply designs.
• Endurance & Temperature Range — Specified for 1,000 hours at 85°C; operating temperature range −40°C to +85°C for reliable performance in ambient and enclosure environments.
• Package & Mounting — Radial snap‑in can (snap‑in terminal) in a compact φ22 × 40 mm form factor for secure chassis/PCB mounting in audio equipment.
• RoHS Compliance & Marking — RoHS‑compliant material set; capacitors are printed with gold color lettering on a black sleeve for clear identification.

Typical Applications

• High‑fidelity audio amplifiers — Bulk reservoir and power-supply smoothing to support low-frequency dynamics and stable rail voltage in audio power stages.
• Audio preamplifiers and signal processing — Decoupling and filtering where large capacitance and controlled dissipation characteristics help maintain audio integrity.
• Audio power supplies — Filtering and ripple suppression in discrete power-supply sections for consumer and professional audio equipment.

Unique Advantages

• Audio-focused grade (TYPE‑II): Electrode foil and construction tuned for audio use—aligns product behavior with high‑fidelity equipment needs.
• High bulk capacitance: 10,000 µF provides substantial energy storage for low-frequency smoothing and reduced supply sag during dynamic audio passages.
• Robust ripple handling: 2.65 A ripple rating at 120 Hz reduces operating stress and heating in power-supply filter banks.
• Broad temperature capability with defined endurance: −40°C to +85°C operating range and 1,000 hours endurance at 85°C for predictable life under specified thermal conditions.
• Secure snap‑in mounting: Radial snap‑in can simplifies mechanical retention and assembly for chassis- or board-mounted filter modules.
• RoHS compliant and clearly marked: Conforms to RoHS directives and uses gold lettering on a black sleeve for quick visual identification.
