Overview of LKS1K122MESY – Snap-in Aluminum Electrolytic Capacitor for Audio Equipment

The LKS1K122MESY is a snap-in terminal aluminum electrolytic capacitor in Nichicon's LKS series, designed for audio equipment and general-purpose applications. It delivers 1.2 mF capacitance at an 80 V rating in a compact snap-in, radial can package optimized for replacement of smaller standard parts to improve tone characteristics.

Built to operate across a wide temperature range and compliant with RoHS (2011/65/EU, (EU)2015/863), the LKS1K122MESY combines audio-focused performance with robust endurance characteristics for reliable service in powered audio and general electronic systems.

Key Features

  • Capacitance & Voltage — 1.2 mF capacitance rated at 80 V for energy storage and decoupling in higher-voltage audio circuits and general-purpose power rails.
  • Snap-in Radial Can Package — Snap-in terminals for secure mechanical mounting to chassis or PC boards; radial, can-style package for straightforward installation and replacement.
  • Audio-focused Design — Part of the LKS series specified “for audio equipment” and noted for tone-quality improvement when replacing smaller standard components.
  • Temperature Range & Endurance — Category temperature range −40 to +85 °C with a rated endurance of 1000 hours at 85 °C as specified by the series datasheet.
  • Leakage Current Specification — Leakage current defined in the datasheet: after 5 minutes at rated voltage and 20 °C, leakage is not more than 3√(C·V) μA (C in μF, V in V).
  • Tolerance & Polarization — Capacitance tolerance ±20% (measured at 120 Hz, 20 °C) and polarized construction for correct orientation in DC circuits.
  • Ripple Current Rating — Specified low-frequency ripple current of 1.7 A at 120 Hz for handling AC ripple in power-supply applications.
  • Compact Dimensions — Small form factor (L: 3 × D: 2 cm) to ease integration where board space and compact enclosures are required.

Typical Applications

  • Audio Equipment — Use as a reservoir or smoothing capacitor in analog audio power supplies; specified for audio applications and suitable for upgrades from smaller standard parts to influence tone quality.
  • Power Supply Filtering — Bulk and decoupling capacitor for higher-voltage rails where 1.2 mF at 80 V is required to reduce ripple and stabilize supply under load.
  • General-Purpose Electronics — Polarized electrolytic for general DC energy storage and smoothing in control and power circuitry across consumer and industrial devices operating within −40 to +85 °C.

Unique Advantages

  • Audio-Optimized Series: Designed and specified for audio equipment with documented benefits when replacing smaller standard parts to improve perceived tone quality.
  • Robust Endurance: Rated for 1000 hours at 85 °C with defined post-endurance limits for capacitance, tan δ and leakage, supporting predictable long-term behavior.
  • Defined Leakage Performance: Leakage current limit expressed by the datasheet formula (≤ 3√(C·V) μA after 5 minutes), enabling predictable power-loss budgeting in designs.
  • Practical Ripple Handling: 1.7 A ripple current rating at 120 Hz supports use in audio and power-supply filtering where AC ripple must be managed.
  • RoHS Compliant: Conforms to RoHS directives (2011/65/EU, (EU)2015/863), facilitating use in commercial and consumer electronics that require restricted-substance compliance.
  • Secure Mounting: Snap-in terminals and radial can package provide reliable mechanical retention for chassis- or board-mounted applications.
