LKSH2272MESC

The LKSH2272MESC is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LKS series, designed specifically for audio equipment and smaller-sized installations. It delivers 2.7 mF capacitance at a 71 V rating in a compact radial can with snap-in mounting.

Part of the LKS series, this capacitor is intended for general-purpose electronic use in applications where improved tone quality is desired by upgrading from smaller standard parts. The device is RoHS compliant.

Key Features

• Electrical Performance — Capacitance: 2.7 mF with a tolerance of −20% to +20%; rated voltage: 71 V; polarized design for correct polarity-aware applications.
• Ripple Handling — Low-frequency ripple current specified at 2.5 A (120 Hz), suitable for power-supply smoothing in audio and general-purpose circuits.
• Thermal and Reliability — Operating temperature range: −40°C to +85°C; endurance specified as 1000 hours at 85°C. Leakage-current specification follows the series requirement of not more than 3√CV (μA) after 5 minutes at 20°C.
• Mechanical and Mounting — Snap-in terminal type in a radial can package for secure board retention and straightforward PCB assembly.
• Compact Footprint — Smaller-sized form factor with dimensions L: 2 × D: 3.5 cm, enabling tighter layouts in audio and electronic equipment.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Series Context (LKS) — The LKS series covers rated voltages from 25 to 100 V and capacitances from 680 μF to 33,000 μF, with series-level characteristics such as tan δ and low-temperature impedance stability documented in the datasheet.

Typical Applications

• Audio Equipment — Used in audio amplifiers and related circuits where replacing smaller standard capacitors can produce an audible improvement in tone quality.
• Power Supply Filtering — Bulk smoothing and ripple reduction in general-purpose power supplies, leveraging the 2.5 A (120 Hz) ripple rating.
• Electronic Equipment — General-purpose decoupling and energy storage in compact electronic and consumer devices requiring a snap-in radial can solution.

Unique Advantages

• Designed for audio tone improvement — Specifically referenced as smaller-sized with an effect on tone quality when used to replace small standard parts.
• High ripple capability for its size — 2.5 A at 120 Hz ripple current supports demanding smoothing tasks in audio power rails.
• Compact, board-friendly package — Snap-in radial can enables secure mechanical retention while minimizing board footprint (L: 2 × D: 3.5 cm).
• Operational temperature range — −40°C to +85°C supports a wide range of environmental conditions for general-purpose electronics.
• Endurance documented — Specified for 1000 hours at 85°C, with post-test limits for capacitance change, tan δ, and leakage current defined by the series specification.
• RoHS compliance — Meets RoHS (2011/65/EU, (EU)2015/863) requirements for restricted substances.
