Key Features

• Audio‑grade design: Engineered for high‑grade audio equipment with a focus on high‑fidelity sound quality as described by the LKG series.
• Capacitance & voltage: 4700 µF (4.7 mF) nominal capacitance with a 100 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Snap‑in, radial can package: Snap‑in terminal mounting (radial, can – snap‑in) for secure PCB installation and mechanical stability.
• Compact dimensions: Case diameter φ35 mm with length 50 mm (size listed as L: 5 × D: 3.5 cm), suitable for power reservoir and filtering in audio power stages.
• Operating temperature & endurance: Rated for −40°C to +85°C with an endurance of 1000 hours at 85°C when operated at rated voltage.
• Ripple capability: Rated ripple current of 4.5 A at 120 Hz, supporting audio power supply decoupling and smoothing.
• Polarized electrolytic: Polarized construction for DC filtering and bulk energy storage in audio circuits.
• RoHS compliant: Conforms to RoHS directive requirements (2011/65/EU, (EU)2015/863).
• Series configuration options: The LKG series offers TYPE‑I, TYPE‑II and TYPE‑III grades for varying audio performance preferences (series‑level information).

Typical Applications

• Professional audio amplifiers: Bulk energy storage and smoothing in amplifier power supplies to support clean, stable power delivery for high‑fidelity output.
• High‑resolution audio equipment: Power filtering and reservoir duties in DACs, preamps, and playback systems where audio fidelity is a priority.
• Studio and broadcast gear: Reliable DC filtering in mixing consoles, studio power supplies, and signal processing racks that demand consistent performance.

Unique Advantages

• Designed for audio fidelity: Series focus on high‑grade audio ensures components and construction target sonic performance requirements.
• High voltage headroom: 100 V rating provides margin for high‑voltage audio and power supply designs.
• High capacitance in a compact can: 4700 µF in a φ35×50 mm package offers substantial bulk capacitance while conserving board space.
• Robust thermal and endurance profile: −40°C to +85°C operating range and 1000‑hour endurance at 85°C for predictable long‑term behavior under rated conditions.
• Strong ripple handling: 4.5 A ripple current at 120 Hz supports filtering performance in audio power rails.
• Regulatory compliance: RoHS compliance supports environmental and regulatory requirements for modern electronics production.
