LKSN2152MESY

The LKSN2152MESY is a snap-in aluminum electrolytic capacitor from Nichicon’s LKS series, optimized for audio equipment and general-purpose applications. It delivers bulk capacitance in a compact radial can with snap-in terminals, offering a balance of audio-oriented performance and board-level mechanical retention.

Key Features

• Capacitance & Rated Voltage — 1.5 mF nominal capacitance with a 56 V rated voltage, providing substantial energy storage for power filtering and decoupling in mid-voltage circuits.
• Snap-in Package — Snap-in terminal type in a radial can package for secure mechanical mounting and straightforward PCB assembly.
• Audio-oriented design — Described as smaller and delivering higher tone quality compared to the LKG TYPE-1 grade, intended specifically for audio equipment applications.
• Operating temperature & endurance — Rated for operation from −40°C to +85°C with an endurance specification of 1000 hours at 85°C when the rated voltage is applied.
• Ripple current — 1.6 A at 120 Hz, suitable for smoothing and ripple handling in power supply stages operating at mains-frequency rectification.
• Electrical characteristics — Polarized capacitor with capacitance tolerance of −20% to +20% and leakage-current specification of not more than 3√(C·V) μA after 5 minutes at 20°C.
• RoHS compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Used in power supply and coupling stages where replacing smaller standard parts can improve perceived tone quality.
• General-purpose Power Filtering — Bulk smoothing and decoupling in mid-voltage power rails that require snap-in mounting and reliable ripple handling.
• Equipment Requiring Secure Mounting — Systems that benefit from snap-in terminal retention for mechanical stability on the PCB.

Unique Advantages

• Audio-focused performance: Designed and specified for audio equipment with a stated improvement in tone quality versus a smaller standard product.
• Substantial bulk storage: 1.5 mF at 56 V provides meaningful capacitance for power smoothing and energy reserve in amplifier and supply circuits.
• Effective ripple handling: 1.6 A ripple current rating at 120 Hz supports mains-rectified power stages and reduces ripple-related noise.
• Wide operating range with defined endurance: −40°C to +85°C operation and a 1000-hour endurance at 85°C under rated voltage provide predictable aging and stability metrics.
• Leakage and endurance specifications: Leakage current limit (≤ 3√CV μA after 5 minutes at 20°C) and post-endurance limits on capacitance and tan δ help with predictable design margins.
• Regulatory compliance: RoHS conformity supports use in designs targeting restricted-substance compliance.
