LKSA2822MESA

The LKSA2822MESA is an 8.2 mF (8200 μF), 42 V snap-in aluminum electrolytic capacitor from Nichicon's LKS series, designed for audio equipment and general-purpose applications. It provides a smaller-sized snap-in radial can option intended to deliver tone-quality improvement when replacing smaller standard products.

Engineered for board-mounted power and audio circuits, this polarized, snap-in terminal capacitor combines a compact footprint (L: 4.5 × D: 2.5 cm) with specifications tuned for reliable operation across a wide temperature range.

Key Features

• Capacitance & Voltage — 8.2 mF (8200 μF) rated at 42 V for bulk energy storage in audio and general-purpose circuits.
• Tolerance & Electrical Character — Capacitance tolerance ±20% (measured at 120 Hz, 20°C); leakage current controlled per datasheet formula for predictable behavior after voltage application.
• Mounting & Package — Snap-in terminal, radial can (snap-in) package for secure PCB mounting and mechanical stability in assemblies.
• Polarized Construction — Polarized aluminum electrolytic design for correct orientation in DC power and audio circuits.
• Temperature Range — Rated for operation from −40°C to +85°C to support a range of environmental conditions.
• Endurance — Specified lifetime of 1000 hours at 85°C with defined limits for capacitance change, tan δ, and leakage.
• Ripple Handling — Low-frequency ripple current rating of 3.2 A at 120 Hz for handling ripple in power-supply and audio applications.
• RoHS Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).
• Marking — Printed with silver color letters on a black sleeve for clear identification.

Typical Applications

• Audio Equipment — Used in audio power supplies and amplifier smoothing stages where replacing smaller standard capacitors can improve perceived tone quality.
• General Purpose Power Filtering — Bulk energy storage and ripple suppression in board-level power circuits for consumer and pro-audio electronics.
• Industrial Electronics — DC link or reservoir capacitor in non-automotive industrial systems operating within the specified temperature and lifetime limits.

Unique Advantages

• Improved tone potential: Sized and specified for audio applications where upgrading from smaller capacitors can produce audible improvements.
• High ripple capability: 3.2 A ripple current rating at 120 Hz supports higher AC stress environments common in power-supply filtering.
• Robust thermal performance: −40°C to +85°C operating range and 1000-hour endurance at 85°C provide predictable long-term behavior under rated conditions.
• Secure snap-in mounting: Radial snap-in can design simplifies PCB assembly while providing reliable mechanical retention.
• Clear identification: Silver-on-black sleeve marking for straightforward part recognition during production and service.
• Regulatory compliance: RoHS-compliant construction supports regulatory requirements for many product lines.
