LKSH2272MESZ

The LKSH2272MESZ is a polarized aluminum electrolytic capacitor in Nichicon’s LKS series, featuring a snap-in radial can package and designed for audio equipment and general-purpose applications. It offers 2.7 mF capacitance at a 71 V rating in a compact 4.0 × 2.2 cm can, aimed at delivering improved tone characteristics when used as an upgrade from smaller standard capacitors.

Engineered for reliability in compact power and audio circuits, this RoHS-compliant unit supports a wide operating temperature range and defined endurance characteristics suitable for equipment-level use.

Key Features

• Capacitance & Voltage — 2.7 mF capacitance rated at 71 V for bulk energy storage and smoothing in power and audio circuits.
• Compact Snap-in Package — Radial, can-style snap-in mounting with overall size L: 4.0 cm × D: 2.2 cm, enabling secure board retention and simplified assembly for chassis-mounted or PCB-mounted designs.
• Audio‑focused Design — Specified for audio equipment with a smaller-sized footprint; described to provide an effect of tone quality improvement when replacing smaller standard parts.
• Electrical Performance — Ripple current rating of 2.5 A at 120 Hz (low frequency) and capacitance tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• Operating Range & Reliability — Rated to operate from −40 °C to +85 °C with a lifetime specification of 1000 hours at 85 °C under applied rated voltage.
• Leakage Current Limit — Leakage current specified as not more than 3√CV (µA) after 5 minutes’ application of rated voltage at 20 °C, per series specification.
• Endurance Characteristics — After endurance test (1000 h at 85 °C with rated voltage), capacitance change is within ±20% and leakage current remains at or below initial specified values (tan δ ≤ 200% of initial specification).
• Regulatory — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).
• Identification — Printed with silver lettering on a black sleeve for clear marking.

Typical Applications

• Audio Equipment — As a replacement or upgrade capacitor in amplifiers and audio power supplies to help achieve the described tone-quality improvement versus smaller standard parts.
• Power Supply Smoothing — Bulk energy storage and ripple filtering in general-purpose DC power supplies where a 71 V rating and 2.7 mF capacitance are required.
• General-Purpose Electronics — Use in electronic equipment requiring polarized electrolytic bulk capacitance with snap-in board mounting and defined endurance at elevated temperature.

Unique Advantages

• Compact, serviceable snap-in form — The radial snap-in can (4.0 × 2.2 cm) enables secure mechanical retention and easier replacement or retrofit in existing assemblies.
• Designed for audio upgrades — Explicitly intended for audio equipment and noted to provide a tone-quality improvement when replacing smaller standard capacitors.
• Measurable ripple capability — 2.5 A ripple current rating at 120 Hz supports low-frequency power-conditioning demands in amplifier and power-supply circuits.
• Defined high-temperature endurance — Lifetime and endurance specifications (1000 hours at 85 °C with rated voltage) give clear expectations for long-term performance under elevated temperature stress.
• Documented leakage limits — Leakage current bounded by the 3√CV (µA) formula after initial voltage application, enabling predictable standby and quiescent behavior.
• RoHS compliance — Meets RoHS directives (2011/65/EU, (EU)2015/863) for restricted substances compliance in compatible assemblies.
