Key Features

• Audio-focused design — Series-level design emphasis for high-grade audio equipment and high-fidelity sound quality.
• Capacitance and voltage — 3.3 mF (3300 µF) nominal capacitance with a 25 V rated voltage and ±20% tolerance for power reservoir and decoupling duties.
• Low-loss characteristic — Specified tangent of loss angle (tan δ) of 0.22 (measured at 120 Hz, 20°C) for controlled dissipation in audio circuits.
• High ripple handling — 2.4 A ripple current rating at 120 Hz supports filtering and smoothing in power stages.
• Leakage current — Typical leakage current specified at 860 µA, allowing predictable bias behavior after voltage application.
• Snap-in, radial can package — Robust snap-in terminals for secure board mounting and straightforward assembly in power modules and chassis-mounted audio assemblies.
• Temperature and reliability — Operates from −40°C to +85°C with a 1000-hour endurance rating at 85°C to meet long-term performance expectations.
• RoHS compliant — Conforms to RoHS requirements as stated for the series.

Typical Applications

• High-grade audio amplifiers — Bulk filtering and power smoothing to support steady supply rails for audio amplifier stages.
• Preamp and signal-chain power sections — Energy storage and decoupling where low loss and stable capacitance contribute to consistent audio performance.
• Audio power supplies — Ripple attenuation and transient support in power supply modules for consumer and professional audio equipment.

Unique Advantages
