LKG1E123MESBBK

The LKG1E123MESBBK is a Nichicon LKG-series snap‑in aluminum electrolytic capacitor specified at 12,000 µF and 25 V. Designed for audio applications, it is a snap‑in, radial can package intended to support power filtering and energy storage in high‑fidelity audio equipment.

This part combines high capacitance, a 3.55 A low‑frequency ripple rating (at 120 Hz), and a temperature range of −40 °C to +85 °C, delivering durable performance where large capacitance and audio‑grade characteristics are required.

Key Features

• Capacitance & Voltage — 12,000 µF nominal capacitance with a rated voltage of 25 V and a tolerance of ±20% (measured at 120 Hz, 20 °C).
• Audio‑Grade Series — Part of the Nichicon LKG series for audio use; the part code suffix BK identifies the TYPE‑II (Gold Tune) grade focused on sound quality via electrode foil design.
• Loss and Leakage — Tangent of loss angle (tan δ) specified at 0.3 (20 °C, 120 Hz) and measured leakage current 1,640 µA, providing clear electrical characteristics for design verification.
• Ripple Current Capability — Low‑frequency ripple current rated at 3.55 A (120 Hz), suitable for smoothing and bulk energy roles in audio power supplies.
• Operating Temperature & Endurance — Rated for −40 °C to +85 °C with an endurance specification of 1,000 hours at 85 °C. After endurance testing and restoration to 20 °C, capacitance change remains within ±20% and tan δ remains within 200% of initial value per series specifications.
• Package & Mounting — Snap‑in radial can construction (φ30 × 45 mm nominal), polarization provided; supplied in tray packing for handling and assembly.
• RoHS Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863) as documented for the LKG series.
• Low‑Temperature Stability — Impedance ratios specified for low temperatures: Z(−25 °C)/Z(+20 °C) ≤ 4 and Z(−40 °C)/Z(+20 °C) ≤ 12, informing cold‑start and low‑temperature performance expectations.

Typical Applications

• High‑Fidelity Audio Equipment — Bulk energy storage and power supply smoothing in HD audio amplifiers and preamplifiers where audio‑grade capacitor characteristics are prioritized.
• Audio Power Supplies — Filtering and decoupling in power rails for audio systems, leveraging the high capacitance and 3.55 A ripple rating at 120 Hz.
• Professional Audio Electronics — Use in mixers, studio processors, and consumer high‑end audio components that specify audio‑focused capacitor grades.

Unique Advantages

• Large Capacitance in a Snap‑In Can — 12,000 µF provides substantial bulk energy for audio power circuits while using a snap‑in radial package for secure PCB mounting.
• Audio‑Focused Grade (TYPE‑II / BK) — Series grading indicates center‑grade, sound‑quality optimization via electrode foil selection, useful when tone and fidelity matter.
• Measured Electrical Parameters — Specified tan δ and measured leakage current provide concrete metrics for designers to evaluate electrical losses and standby drain.
• Robust Ripple Handling — 3.55 A low‑frequency ripple capability at 120 Hz supports smoothing under typical audio power conditions.
• Wide Operating Range and Endurance — −40 °C to +85 °C rating with 1,000 hours endurance at 85 °C aligns with long‑term performance expectations for stationary audio equipment.
• RoHS‑Compliant — Meets current RoHS requirements, facilitating environmental and regulatory alignment in product designs.
