LKG1H122MESBCK

The LKG1H122MESBCK is an aluminum electrolytic capacitor in a snap‑in radial can designed for audio applications. It provides 1.2 mF (1200 μF) capacitance at a 50 V rating with ±20% tolerance, packaged for snap‑in mounting.

Built for audio equipment use within the Nichicon LKG series, this part combines a compact footprint (φ30 × 25 mm) with a specified ripple current of 1.9 A (120 Hz), low leakage characteristics, and endurance testing of 1000 hours at 85°C for reliable performance in audio power supply and smoothing roles.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 μF) rated at 50 V with ±20% tolerance (measured at 120 Hz, 20°C), suitable for bulk energy storage and decoupling in audio power stages.
• Audio‑Focused Series — Part of the Nichicon LKG family, which is specified "for audio use" and designed with tone quality and high‑grade audio applications in mind.
• High Ripple Current — Rated ripple current of 1.9 A at 120 Hz, enabling effective smoothing and filtering in audio power supplies.
• Low Leakage — Product listing shows leakage current of 730 μA; the LKG series datasheet specifies the leakage limit using the 3√(C·V) rule after 5 minutes at 20°C.
• Package & Mounting — Snap‑in terminal, radial can construction for secure board mounting; nominal size φ30 × 25 mm (L: 2.5 cm × D: 3.0 cm).
• Temperature & Endurance — Rated operating range −40°C to +85°C with endurance specified as 1000 hours at 85°C (restored to 20°C for final measurement).
• Regulatory — RoHS compliant, reflecting adherence to applicable restricted substance requirements included in the product data.

Typical Applications

• High‑Fidelity Audio Equipment — Bulk filtering and power smoothing in amplifiers and preamplifiers where audio quality and stable power rails are required.
• Professional Audio Electronics — Energy storage and decoupling in mixing consoles, studio equipment, and audio processing hardware.
• Power Supply Filtering — Line and post‑regulator smoothing in audio power supplies, leveraging the rated ripple current for effective performance at 120 Hz.

Unique Advantages

• Audio‑centric design: Specified in the LKG series "for audio use," making the part appropriate where tone quality and sound fidelity are priorities.
• High ripple handling: 1.9 A ripple current rating at 120 Hz supports robust filtering and reduces voltage ripple under audio load conditions.
• Compact snap‑in package: φ30 × 25 mm radial can with snap‑in terminals simplifies PCB mounting while providing a secure mechanical and electrical connection.
• Wide temperature range with proven endurance: −40°C to +85°C rating and 1000 hours endurance at 85°C provide measurable reliability data for design validation.
• Measurable leakage control: Low leakage (product listing: 730 μA) and datasheet leakage limits (3√(C·V) after 5 minutes at 20°C) allow predictable bias and discharge behavior in circuits.
• RoHS compliance: Conforms to RoHS directives as indicated in the product information, supporting environmental compliance requirements.
