LKG1J122MESABK

The LKG1J122MESABK is an aluminum electrolytic, snap-in terminal capacitor from Nichicon's LKG series, engineered specifically for audio equipment. It is a TYPE-II grade unit (code BK) designed to prioritize high-fidelity sound quality for HD audio applications.

Key electrical and mechanical attributes include a capacitance of 1.2 mF, a 63 V rated voltage, snap-in radial can package, and RoHS compliance. These characteristics make it suitable for power filtering and decoupling tasks in audio power supplies and signal-related circuits where audible quality is important.

Key Features

• Audio-grade design (TYPE-II) — The BK code denotes TYPE-II grade; configured for center-grade performance aimed at delivering improved sound quality using electrode foil for versatile use.
• Capacitance and rating — 1.2 mF capacitance with a 63 V rated voltage and ±20% tolerance, providing bulk energy storage and filtering capacity for audio power stages.
• Snap-in radial can package — Snap-in mounting and radial can construction simplify secure chassis or PCB installation in rack, amp, and enclosure designs.
• Ripple current handling — Rated ripple current of 1.9 A at 120 Hz supports power-supply ripple smoothing in audio applications.
• Operating and endurance profile — Specified operating range of −40°C to +85°C with endurance defined as 1000 hours at 85°C; after this test the capacitance change is within ±20% and leakage current remains within initial limits.
• Polarized construction — Polarized electrolytic capacitor for DC power applications commonly found in audio amplifiers and power supply rails.
• RoHS compliant and identifiable marking — Complies with RoHS (2011/65/EU, (EU)2015/863) and is printed with gold-color lettering on a black sleeve for easy identification.
• Compact footprint — Physical dimensions L: 2.5 × D: 2.5 cm and a seated height specification suitable for low-profile audio installations.

Typical Applications

• High-grade audio amplifiers — Bulk energy storage and ripple filtering in amplifier power supplies to support consistent audio performance.
• HD audio systems — Designed to meet high tone-quality requirements in HD audio equipment where sound fidelity is a priority.
• Professional and studio equipment — Suitable for power rail decoupling and smoothing in mixing consoles, preamps, and other studio gear.
• Consumer audio electronics — Used in home audio components where a compact, snap-in electrolytic provides reliable filtering and power conditioning.

Unique Advantages

• Audio-focused grade: TYPE-II (BK) grade provides center-grade performance targeted at improved sound characteristics using electrode foil construction.
• High voltage capability: 63 V rating allows use in higher-voltage rails within audio power supplies and related circuits.
• Robust ripple handling: 1.9 A ripple current rating at 120 Hz supports effective smoothing under typical audio supply loads.
• Durability under stress: 1000 hours endurance at 85°C with defined post-test limits for capacitance, tan δ, and leakage current ensures predictable long-term behavior.
• Installation-friendly package: Snap-in radial can simplifies mechanical mounting in chassis and PCB assemblies.
• Regulatory compliance and clear ID: RoHS compliance and gold-on-black sleeve marking ease regulatory alignment and part identification.
