LKSA2272MESZ

The LKSA2272MESZ is a snap-in, radial can aluminum electrolytic capacitor from Nichicon's LKS series, designed for audio equipment and general-purpose applications. It delivers 2.7 mF rated capacitance at 42 V in a compact snap-in package, combining a smaller footprint with specifications targeted at reliable power filtering and mechanical board retention.

Engineered for -40 °C to 85 °C operation and a rated lifetime of 1000 hours at 85 °C, this RoHS-compliant component is intended for designs that require a compact, durable electrolytic capacitor with measurable ripple handling and defined endurance characteristics.

Key Features

• Capacitance & Voltage — 2.7 mF nominal capacitance with a 42 V rated voltage and tolerance of ±20% (–20% to +20%).
• Snap-in Radial Can Package — Snap-in mounting provides secure mechanical retention for through‑hole PCB designs; package type listed as radial, can - snap-in.
• Compact Dimensions — Small-sized construction with overall dimensions L: 2.5 × D: 2.2 cm and maximum seated height 2.5 cm, supporting space‑constrained layouts.
• Temperature & Endurance — Operating range −40 °C to +85 °C; endurance specification of 1000 hours at 85 °C with defined limits on capacitance change, tan δ, and leakage current after test.
• Ripple Handling — Rated low-frequency ripple current of 1.7 A at 120 Hz for specified operating conditions.
• Leakage Current Specification — After 5 minutes’ application of rated voltage at 20 °C, leakage current is specified as not more than 3√CV (μA), where C is capacitance (μF) and V is voltage (V), per datasheet standard.
• Polarized Device — Polar capacitor construction suitable for circuits that accept a polarized electrolytic capacitor.
• RoHS Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863), supporting regulatory requirements for electronics assemblies.
• Marking — Identified with silver color printing on a black sleeve for easy visual verification.

Typical Applications

• Audio Equipment — Intended for use in audio systems where replacing a smaller standard product can produce a measurable effect on tone quality; suitable where designers require audio-focused electrolytic capacitors.
• General-Purpose Power Filtering — Provides bulk capacitance and ripple handling for general-purpose smoothing and filtering in power supply circuits that accept snap-in radial cans.
• Board-Mounted Power Modules — Snap-in mounting offers robust mechanical attachment for through‑hole PCB assemblies in compact power modules and chassis-mounted electronics.

Unique Advantages

• Compact audio-focused form factor: Smaller-sized LKS construction targets applications where space is limited but audio performance impact is desired.
• Secure mechanical mounting: Snap-in terminal design improves board retention and mechanical stability compared with loose-leaded alternatives.
• Defined ripple capability: The 1.7 A (120 Hz) ripple current rating provides a quantifiable parameter for thermal and ripple-loss design tradeoffs.
• Clear endurance specification: 1000 hours at 85 °C with specified limits on capacitance change, tan δ, and leakage current supports predictable lifetime planning.
• Regulatory alignment: RoHS compliance simplifies integration into regulated product lines and global shipments.
