Key Features

• Capacitance & Voltage — Rated capacitance of 4.7 mF (4.7 mF) with an 80 V working voltage, suitable for higher-voltage audio and general-purpose circuits.
• Snap-in Terminal Package — Snap In mounting, radial can design provides secure panel/PCB mounting for power and filter applications.
• Audio-focused, Smaller-sized Design — Specified for audio equipment and described as smaller-sized; recommended as a replacement upgrade from smaller standard products to improve tone quality.
• Operating Temperature & Endurance — Rated for −40 °C to +85 °C with an endurance rating of 1000 hours at 85 °C, meeting stability and life expectations for sustained use.
• Ripple Current Capability — Low-frequency ripple current rating of 3.6 A at 120 Hz for effective smoothing in power circuits.
• Polarized Construction — Polarized electrolytic design for DC applications where polarity-aware capacitors are required.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances.
• Compact Size — Physical size noted as L: 4 × D: 3 cm, providing a smaller footprint for space-constrained designs.

Typical Applications

• Audio Equipment — Used as power supply and smoothing capacitors or as upgrade replacements in audio circuits to help improve perceived tone quality.
• General Purpose Electronics — Suitable for a wide range of general-purpose DC filtering and decoupling applications in electronic assemblies.
• Power Filtering — Employed where polarized, high-capacitance components are required to manage low-frequency ripple and stabilize supply rails.
