LKSH2222MESA

The LKSH2222MESA is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LKS series, designed for audio equipment and general-purpose use. Its smaller-sized snap-in can and specified electrical characteristics make it suitable for replacing standard parts to achieve audible tone-quality improvement in audio circuits.

Key attributes include a 2.2 mF capacitance at 71 V, polarized construction, RoHS compliance, and a compact radial snap-in package for robust panel or board mounting.

Key Features

• Capacitance & Voltage — 2.2 mF nominal capacitance rated at 71 V for energy storage and filtering in mid- to high-voltage audio and general-purpose circuits.
• Snap-in Radial Can Package — Snap-in mounting type in a radial, can-style package with dimensions L: 2.5 × D: 2.5 cm and a seated height of 2.5 cm for secure, easy installation.
• Polarized Construction — Designed as a polarized electrolytic capacitor for DC filtering and bulk decoupling applications.
• Operating Temperature — Rated for −40 °C to +85 °C to support a wide range of operating environments.
• Endurance — Specified lifetime of 1000 hours at 85 °C with voltage applied, meeting LKS series endurance criteria for long-term operation.
• Ripple Current (120 Hz) — 2.25 A ripple current rating at 120 Hz, suitable for low-frequency filtering and power smoothing tasks.
• Capacitance Tolerance — ±20% tolerance (measured at 120 Hz, 20 °C) for predictable performance in filter and coupling networks.
• RoHS Compliant — Conforms to RoHS directives noted for the LKS series (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Bulk filtering and coupling in amplifiers and audio power supplies where replacement with a smaller, higher-tone-quality capacitor can improve perceived sound quality.
• Power Supply Smoothing — DC smoothing and ripple reduction in general-purpose power supplies and regulator circuits operating within the rated voltage and temperature range.
• Replacement/Upgrade — Direct replacement for small standard snap-in electrolytic capacitors to improve tonal characteristics and maintain compact packaging.

Unique Advantages

• Tone-Quality Focused Design — Marketed for audio equipment with a smaller-sized LKS construction intended to deliver audible improvements when used as a replacement part.
• Compact Snap-In Form Factor — Radial, snap-in can with compact 2.5 × 2.5 cm footprint and secured mounting for reliable mechanical retention and simplified assembly.
• Robust Ripple Handling — 2.25 A ripple current rating at 120 Hz enables effective low-frequency filtering without excessive heating under rated conditions.
• Wide Operating Range — −40 °C to +85 °C rating supports a range of ambient conditions commonly encountered in consumer and professional audio equipment.
• Endurance for Long-Term Use — 1000 hours at 85 °C endurance specification provides a measurable reliability baseline for design validation.
• Regulatory Compliance — RoHS compliance supports use in products targeting regulated markets.
