LKG1H272MESZBK

The LKG1H272MESZBK is a 2700 µF, 50 V aluminum electrolytic snap‑in capacitor designed for high‑grade audio equipment where high fidelity sound is a priority. It is part of the Nichicon LKG series, a family developed specifically for audio applications with variation grades that address different tonal and construction preferences.

This snap‑in, radial can package (22 mm diameter × 45 mm length) offers polarized capacitance with a ±20% tolerance, measured at 120 Hz and 20°C, and is RoHS compliant (2011/65/EU, (EU)2015/863).

Key Features

• Audio‑focused design — Developed for high‑grade audio equipment with series variations (TYPE‑I, TYPE‑II, TYPE‑III) that prioritize tone quality and sound fidelity.
• Capacitance & voltage — 2.7 mF (2700 µF) rated at 50 V with ±20% tolerance, suitable for power smoothing and energy storage in audio power supplies.
• Low loss (tan δ) — Specified tan δ of 0.3 (measurement frequency 120 Hz at 20°C), supporting low dissipation in audio signal and power paths.
• Ripple handling — Rated ripple current of 2.45 A at 120 Hz, supporting typical low‑frequency power filtering in audio equipment.
• Reliability and lifetime — Endurance rating: 1000 hours at 85°C with specified limits for capacitance change, tan δ and leakage current after the test; shelf life and leakage limits defined per datasheet.
• Temperature performance — Operating range from −40°C to +85°C with low‑temperature impedance stability (Z(−25°C)/Z(+20°C) ≤ 4, Z(−40°C)/Z(+20°C) ≤ 12 at 120 Hz for rated voltages).
• Mechanical/package — Snap‑in radial can package for board mounting; compact footprint with overall size approximately 22 mm diameter × 45 mm length.
• Leakage current specification — After 5 minutes at rated voltage and 20°C, leakage current is specified as not more than 3√(C·V) μA (C in μF, V in V) per the datasheet.
• RoHS compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑end audio amplifiers — Bulk smoothing and power reservoir duties where capacitor characteristics influence dynamic range and tonal balance.
• Professional audio equipment — Power supply filtering and decoupling in mixers, studio preamps and other HD audio systems requiring long term stability.
• Consumer high‑fidelity gear — Used in power sections of home audio components where compact snap‑in mounting and reliable ripple performance are required.

Unique Advantages

• Audio‑centred engineering — LKG series development emphasizes sound quality, offering graded variations (TYPE‑I/II/III) aligned to different tonal requirements.
• Measurable electrical performance — Clear specifications for tan δ, ripple current and leakage current provide predictable behavior when designing audio power rails.
• Compact snap‑in form factor — Radial can, snap‑in mounting simplifies PCB assembly for power supply modules in constrained enclosures.
• High temperature endurance — 1000 hours at 85°C endurance characterization helps ensure component longevity in demanding audio environments.
• Low‑temperature stability data — Published impedance ratios at −25°C and −40°C allow designers to assess performance across the specified operating range.
• Regulatory compliance — RoHS compliance supports environmental and materials requirements for international product lines.
