• Capacitance & Voltage 4.7 mF (4700 µF) rated at 16 V with ±20% tolerance, providing bulk energy storage for audio power stages and supply smoothing.
• Electrical Loss and Ripple Performance Specified tangent of loss angle (tan δ) of 0.35 at 20°C / 120 Hz and low‑frequency ripple current rating of 1.75 A at 120 Hz to support audio supply demands.
• Leakage & Endurance Leakage current specified at 820 µA and life/endurance rated to 1000 hours at 85°C with recovery to room temperature meeting endurance criteria.
• Temperature Range Operating temperature from −40°C to +85°C to cover a broad range of audio equipment environments.
• Package & Mounting Snap‑in radial can (φ22 × 25 mm) for secure chassis or PCB mounting; supplied in tray packing for handling and assembly.
• RoHS‑Compliant Manufactured in compliance with RoHS requirements.
• Distinctive Marking Printed with gold‑color lettering on a black sleeve for clear identification consistent with the LKG series marking scheme.

Typical Applications

• High‑Fidelity Audio Amplifiers Bulk energy storage and smoothing in power rails to support clean, stable supply performance for amplifier stages.
• Preamplifiers and Signal Conditioning Local decoupling and supply buffering where audio‑grade capacitor characteristics contribute to consistent tonal behavior.
• Audio Power Supplies Filtering and ripple attenuation in supply circuits for consumer and professional audio equipment operating within the specified temperature range.

Unique Advantages

• Audio‑Focused Grade: As a Type‑II LKG part (code BK), the component is tailored to audio applications where balanced tonal response and versatility are priorities.
• High Ripple Handling: 1.75 A low‑frequency ripple current rating at 120 Hz supports demanding supply ripple conditions common in audio power stages.
• Compact Snap‑In Form Factor: φ22 × 25 mm snap‑in can provides a space‑efficient solution for chassis or board mounting while maintaining high capacitance.
• Endurance at Elevated Temperature: Rated for 1000 hours at 85°C, enabling predictable lifespan characteristics under thermal stress and recovery to specified limits.
• Traceable Identification: Gold lettering on a black sleeve simplifies part identification during assembly and service.
• Regulatory Compliance: RoHS‑compliant construction supports environmental requirements in regulated markets.
