LKG1H472MESABK

The LKG1H472MESABK from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LKG series, rated 4700 µF (4.7 mF) at 50 V with ±20% tolerance. Engineered for audio applications, this TYPE‑II (BK) grade unit emphasizes balanced fidelity and broad usability through electrode foil optimization.

Its snap‑in radial can package and audio‑focused construction make it suitable for power filtering and energy smoothing in high‑grade and HD audio equipment, while meeting RoHS requirements.

Key Features

• High Capacitance: 4700 µF (4.7 mF) provides bulk energy storage and smoothing for audio power rails.
• Rated Voltage: 50 V rating supports common amplifier and audio power supply voltages.
• Audio‑Oriented Grade (TYPE‑II — BK): Center grade optimized with electrode foil for sound quality and multiple use in audio equipment.
• Snap‑In, Radial Can Package: Snap‑in terminal mounting for secure PCB installation and robust mechanical retention.
• Operating Temperature and Endurance: Specified for −40 °C to +85 °C with an endurance specification of 1000 hours at 85 °C (capacitance change within ±20%).
• Loss and Ripple Characteristics: Specified tan δ of 0.3 (measurement at 120 Hz, 20 °C) and rated ripple current of 3.4 A at 120 Hz for stable performance under AC load.
• Leakage Current Specification: Leakage current after 5 minutes at 20 °C does not exceed 3√(C·V) μA, providing predictable DC behavior for precision audio circuits.
• Compact Dimensions: 25 mm diameter × 35 mm length in a snap‑in can suitable for space‑conscious audio designs.
• RoHS Compliant: Meets RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances.

Typical Applications

• High‑Grade Audio Amplifiers: Bulk filtering and energy buffering on amplifier rails to support transient response and reduce supply ripple.
• HD Audio Equipment: Power smoothing in high‑fidelity preamps and consumer/professional audio gear where tonal clarity is a priority.
• Power Supply Reservoirs: Energy storage and decoupling in audio power supplies to maintain stable voltage under dynamic load.

Unique Advantages

• Audio‑Focused Electrolyte and Foil: TYPE‑II construction targets tonal balance and broad applicability in audio circuits.
• High Bulk Capacitance in a Compact Can: 4700 µF in a 25 mm × 35 mm package saves board space while delivering required energy storage.
• Robust Endurance Rating: 1000 hours at 85 °C with defined limits for capacitance, tan δ and leakage current supports reliable long‑term operation.
• Predictable AC Performance: Specified tan δ and ripple current at 120 Hz enable designers to model thermal and AC behavior accurately.
• Snap‑In Mounting for Mechanical Stability: Radial snap‑in terminals provide secure PCB attachment in assemblies subject to vibration or handling.
• RoHS Compliance: Meets contemporary environmental substance restrictions for global product integration.
