Key Features

• Capacitance and Voltage — 3.9 mF nominal capacitance with a 35 V rated voltage and ±20% tolerance, suitable for bulk energy storage in polarized circuits.
• Snap-in Radial Package — Snap-in terminal, radial can construction for secure chassis or board mounting while saving assembly time compared with threaded or screw-mount types.
• Audio-focused Performance — Specifically marketed for audio equipment with an indicated effect of tone-quality improvement when replacing small standard capacitors.
• Temperature and Lifetime — Rated for -40 °C to +85 °C with an endurance specification of 1000 hours at 85 °C; capacitance change is within ±20% after endurance testing per the datasheet.
• Leakage and Loss Characteristics — Leakage current specified as not more than 3√CV (μA) after 5 minutes at rated voltage (20 °C); tangent of loss angle (tan δ) measured at 120 Hz, 20 °C with endurance allowance up to 200% of initial specified value.
• Ripple Current — Low-frequency ripple capability: 1.7 A at 120 Hz, suitable for smoothing applications at mains-related frequencies.
• Compact Dimensions — Smaller-sized can with overall dimensions L: 2.5 cm × D: 2.2 cm and a seated height max of 2.5 cm for space-constrained layouts.
• Regulatory — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Bulk filtering and energy storage in amplifiers and audio circuits where replacing a small standard capacitor can improve perceived tone quality.
• General-Purpose Electronics — Polarized bulk capacitance for smoothing and decoupling in a variety of general-purpose power supply designs.
• OEM and Retrofit Designs — Compact snap-in form factor for equipment upgrades or replacements where space and improved audio characteristics are priorities.

Unique Advantages

• Audio-oriented specification — Marketed for audio equipment with a documented effect on tone quality when used as a replacement for smaller standard capacitors.
• High bulk capacitance in a compact package — 3.9 mF in a 2.5 × 2.2 cm can provides significant energy storage while conserving board/chassis space.
• Snap-in mounting for secure installation — Snap-in terminals simplify assembly and mechanical retention compared with loose-lead types.
• Defined endurance and shelf-life — Endurance: 1000 hours at 85 °C with capacitance within ±20% and leakage within initial limits; shelf-life treatment and requirements are specified in the datasheet.
• Measurable leakage and loss specifications — Leakage current specified by the 3√CV formula and tan δ measured at 120 Hz/20 °C supports predictable design margins.
• RoHS compliant — Meets the RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances.
