Key Features

• Capacitance & Voltage: 3.9 mF (3.9 mF) rated at 63 V, providing substantial bulk capacitance for decoupling and energy storage in audio and general-purpose circuits.
• Package & Mounting: Snap-in terminal, radial can (snap-in) package that supports secure board mounting in vertical assemblies.
• Audio-focused Performance: Marketed for use in audio equipment with a smaller-sized design that can contribute to tone-quality improvement when replacing smaller standard parts.
• Ripple Current Capability: Rated ripple current of 2.7 A at 120 Hz, suitable for applications with AC ripple at typical line frequencies.
• Temperature & Endurance: Operating temperature range of −40 °C to +85 °C with an endurance rating of 1000 hours at 85 °C under rated voltage conditions.
• Tolerance & Polarization: Capacitance tolerance of ±20% and polarized construction, appropriate for circuits that require electrolytic polarity.
• Environmental Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Dimensions: Physical size approximately L: 4.0 cm × D: 2.2 cm, offering a smaller footprint relative to larger snap-in designs.

Typical Applications

• Audio Equipment: Used in audio circuits where replacing a small standard capacitor can yield a measurable tone-quality improvement and where polarized bulk capacitance is required.
• General-Purpose Electronics: Suitable for general-purpose applications that require polarized aluminum electrolytic capacitors with snap-in mounting.
• Power Filtering in Consumer and Pro Audio Systems: Applied where 3.9 mF at 63 V bulk capacitance and 2.7 A ripple capability at 120 Hz are needed for smoothing and decoupling.

Unique Advantages

• Designed for audio tone improvement: Specifically specified for audio equipment and noted for delivering tonal benefits when replacing small standard capacitors.
• Robust ripple handling: 2.7 A ripple current rating at 120 Hz supports applications with significant AC ripple at line-related frequencies.
• Thermal endurance: Rated for 1000 hours at 85 °C under rated voltage, providing predictable performance over the specified lifetime condition.
• Wide operating temperature: Operates from −40 °C to +85 °C, accommodating a broad range of ambient conditions.
• RoHS-compliant construction: Meets RoHS (2011/65/EU, (EU)2015/863) requirements for restricted substances.
• Compact snap-in form factor: Smaller-sized radial can with snap-in terminals enables higher-density assemblies compared with larger snap-in variants.
