LKSH2122MESY

The LKSH2122MESY is a snap-in terminal aluminum electrolytic capacitor in Nichicon's LKS series designed for audio equipment and general-purpose applications. It offers a compact snap-in can package with polarization and a capacitance of 1.2 mF at a rated voltage of 71 V.

Engineered for compact assemblies, the part provides measurable tone-quality improvement when replacing smaller standard capacitors, while delivering defined endurance and ripple-handling characteristics for reliable performance in typical audio and power-electronic environments.

Key Features

• Capacitance & Voltage — 1.2 mF nominal capacitance with a 71 V rated voltage, suitable for applications requiring this specific energy-storage point.
• Compact Snap‑In Package — Radial, can-style snap-in mounting with physical size L: 2.5 × D: 2 cm and a seated height up to 2.5 cm for space-constrained assemblies.
• Polarized, General‑Purpose — Polar capacitor construction intended for general-purpose use and specifically indicated for audio equipment.
• Operating Range — Rated for operation from −40 °C to +85 °C to cover common environmental conditions for electronic equipment.
• Endurance — Rated lifetime of 1000 hours at 85 °C; after this test condition, capacitance change remains within ±20%, and leakage/tan δ meet specified recovery criteria.
• Ripple Handling — Low-frequency ripple current rating of 1.6 A at 120 Hz for stable filtering and decoupling at that frequency.
• Leakage Current Specification — After 5 minutes at rated voltage and 20 °C, leakage current is specified not more than 3√(C·V) μA (where C is μF and V is volts).
• RoHS Compliant — Conforms to RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Used in audio circuitry where replacing smaller standard capacitors can improve perceived tone quality while providing stable capacitance and ripple performance.
• General‑Purpose Electronic Equipment — Suitable for applications requiring a polarized aluminum electrolytic capacitor at 1.2 mF / 71 V with snap-in mounting.
• Power Filtering at 120 Hz — Employed where low-frequency ripple handling is required, leveraging the 1.6 A ripple rating at 120 Hz.

Unique Advantages

• Compact form factor with snap‑in convenience: The radial snap-in can and small physical dimensions (L: 2.5 × D: 2 cm) simplify mechanical installation in dense assemblies.
• Audio-focused performance: Specified for use in audio equipment and noted for tone-quality improvement when replacing smaller standard parts.
• Defined endurance profile: 1000 hours at 85 °C with controlled post-test capacitance and leakage behavior supports predictable long-term performance planning.
• Clear leakage specification: Leakage current limit defined by the 3√(C·V) μA rule provides a verifiable electrical parameter for design validation.
• Rated ripple capability: 1.6 A at 120 Hz gives a measured basis for specifying filter and smoothing performance at low frequency.
• Directive compliance: RoHS conformity supports use in products targeting markets that require restricted-substance compliance.
