Overview of LKS1E123MESY – Snap-in Aluminum Electrolytic Capacitor (25 V, 12 mF)
The LKS1E123MESY is a snap-in terminal aluminum electrolytic capacitor designed for audio equipment and general-purpose power filtering. It delivers 12,000 µF (12 mF) capacitance at a 25 V rating in a smaller-sized, radial snap-in can intended to improve tone quality when replacing smaller standard capacitors.
Key operational characteristics include a -40 °C to +85 °C temperature range, a rated lifetime of 1,000 hours at 85 °C, and RoHS compliance (2011/65/EU, (EU)2015/863), making it suitable for equipment-level power smoothing and reservoir applications in audio systems and other general-purpose electronics.
Key Features
- Capacitance & Voltage — 12,000 µF (12 mF) capacitance with a 25 V rated voltage and ±20% tolerance, providing bulk energy storage for power supply filtering and reservoir duties.
- Snap-in Radial Can — Snap-in terminal mounting in a radial can package for secure chassis or board retention in larger power modules and audio assemblies.
- Audio-focused, Smaller-sized — Marketed for audio equipment with a smaller footprint than comparable LKG TYPE-1 parts, intended to provide a tone quality improvement when substituted for smaller standard capacitors.
- Operating Range & Endurance — Specified for -40 °C to +85 °C operation with endurance rated to meet capacitance, tan δ and leakage limits after 1,000 hours at 85 °C.
- Ripple Performance — Rated ripple current of 2.65 A at 120 Hz (for the 20 × 50 mm size), supporting smoothing of rectified supplies and audio power stages.
- Loss Angle (tan δ) — tan δ = 0.30 measured at 120 Hz, 20 °C (part-specific value for the 12,000 µF / 25 V size).
- Leakage Current Specification — Leakage current after 5 minutes at 20 °C is specified as not more than 3√CV (µA) [C: µF, V: V], per the datasheet requirement.
- RoHS Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).
- Physical Size — Size listed as approximately L: 5 × D: 2 cm (20 × 50 mm for this part code), with marking printed in silver on a black sleeve for easy identification.
Typical Applications
- Audio Equipment — Bulk filtering and reservoir capacitance in amplifiers and power supplies where improved tone quality is desired by upgrading from smaller standard capacitors.
- General Purpose Power Supplies — Smoothing and decoupling in power rails for consumer and pro-audio electronics operating within the specified temperature range.
- Power Modules and Chassis-mounted Systems — Snap-in mounting offers mechanical stability for larger capacitors used in bench and rack systems requiring robust retention.
Unique Advantages
- High Bulk Capacitance in a Compact Snap-in Can: 12,000 µF at 25 V provides substantial energy storage while maintaining a smaller-sized profile compared to some standard parts.
- Audio-Oriented Design Goal: Marketed specifically for audio equipment with an expected tone-quality improvement when replacing smaller capacitors.
- Measured Loss and Ripple Ratings: Specified tan δ (0.30 at 120 Hz, 20 °C) and rated ripple current (2.65 A at 120 Hz) give engineers clear, testable performance parameters for design validation.
- Endurance-Backed Reliability: Endurance defined by 1,000 hours at 85 °C with limits for capacitance change, tan δ increase and leakage current ensures predictable behavior over the rated life.
- Regulatory Compliance: RoHS conformity supports use in regions requiring restricted substance compliance without additional qualification work.
Why Choose LKS1E123MESY?
LKS1E123MESY positions itself as a high-capacitance, snap-in aluminum electrolytic solution targeted at audio and general-purpose power applications where increased bulk capacitance and stable ripple handling are required. Its measured electrical characteristics (12,000 µF at 25 V, 2.65 A ripple at 120 Hz, tan δ 0.30) and defined endurance make it suitable for engineers needing verifiable filtering performance within the -40 °C to +85 °C operational window.
This part is appropriate for designers upgrading from smaller standard capacitors to improve audio system performance or increase hold-up in power supplies, while maintaining RoHS compliance and predictable lifetime behavior backed by datasheet endurance criteria.
