LKG1J122MESAAK

The LKG1J122MESAAK is a Nichicon LKG series snap‑in aluminum electrolytic capacitor specified at 1.2 mF (1200 µF) and 63 V, engineered for high‑grade audio equipment where fidelity is prioritized. As a TYPE‑I (AK) grade of the LKG family, it features a low‑profile, tone‑quality focused electrolyte formulation intended for HD audio applications and equipment power rails.

Key Features

• Capacitance & Voltage: 1.2 mF (1200 µF) rated at 63 V for bulk energy storage and decoupling in audio power supplies.
• TYPE‑I Audio Grade (AK): Low‑profile, high‑tone quality grade of the LKG series designed with a new electrolyte for improved audio characteristics.
• Snap‑In Mounting: Radial, can style with snap‑in terminals for secure chassis or PCB mounting and easier assembly.
• Operating Range: Specified for −40 °C to +85 °C operating temperature and a rated endurance of 1000 hours at 85 °C under rated voltage.
• Ripple Handling: Rated ripple current of 1.65 A at 120 Hz (low frequency) to support power supply filtering in audio circuits.
• Polarized: Polarized aluminum electrolytic construction for DC bulk-capacitance applications.
• Tolerance & Stability: Capacitance tolerance ±20% at 120 Hz, 20 °C; impedance stability specified for low‑temperature performance (Z(−25 °C)/Z(+20 °C) ≤ 4, Z(−40 °C)/Z(+20 °C) ≤ 12 for the series).
• RoHS Compliant: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Marking: Identified with gold color printing on a black sleeve as part of LKG series marking convention.

Typical Applications

• High‑Grade Audio Amplifiers: Bulk filtering and power decoupling where audio fidelity and stable supply rails are required.
• HD Audio Equipment: Power supply smoothing in consumer and professional HD audio devices that prioritize tone quality.
• Power Supply Reservoirs: Energy storage for linear and discrete switching supplies in audio electronics, leveraging the 1.2 mF capacitance at 63 V.

Unique Advantages

• Audio‑Focused Electrolyte: TYPE‑I low‑profile electrolyte formulation tuned for tone quality, delivering a component designed specifically with audio performance in mind.
• Assembly‑Friendly Snap‑In Package: Radial can with snap‑in terminals simplifies mechanical retention and placement in chassis or PCB assemblies.
• Verified Endurance: Endurance characterized to meet specified values after 1000 hours at 85 °C with rated voltage applied, supporting predictable long‑term behavior.
• Measured Ripple Capability: 1.65 A ripple current rating at 120 Hz provides a quantified basis for selecting this capacitor in audio power supply designs.
• Wide Operating Temperatures: −40 °C to +85 °C specification supports a broad range of environmental conditions encountered in audio equipment.
• Regulatory Compliance: RoHS conformity supports use in designs requiring hazardous‑substance compliance.
