Key Features

• Capacitance & Voltage — 4.7 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance, suitable for a range of audio crossover values.
• Bi‑Polar Construction — Bi‑polarized electrolytic design specified for speaker network use, appropriate where polarity reversals can occur in crossover circuits.
• Audio‑Focused Electrical Performance — Low loss characteristics with tan δ ≤ 0.10 at 1 kHz and ≤ 0.15 at 5 kHz; leakage current specified at 7.05 µA (typical table value for this capacitance and voltage) after standard test conditions.
• Ripple Handling — Allowable continuous current characterized at 4.2 kHz with rated ripple current of 480 mArms, supporting real-world audio ripple and transient demands.
• Package & Mounting — Radial lead, can‑type package (φD × L = 10 × 20 mm) with 5 mm lead spacing for straightforward through‑hole mounting and mechanical stability.
• Operating Range & Marking — Operates from –40 °C to +85 °C; sleeve is printed with white lettering on a black background for clear identification.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Hi‑Fi Speaker Crossovers — Designed specifically for crossover networks in Hi‑Fi sound systems, providing the capacitance and bipolar behavior expected in speaker filter paths.
• Passive Audio Filters — Useful in passive filter sections where stable audio‑frequency loss and controlled leakage current matter for tone and clarity.
• General‑Purpose Audio Circuits — Suitable for audio coupling and filtering tasks in consumer and pro audio electronics requiring a compact radial can package.

Unique Advantages

• Audio‑oriented design — Bi‑polar series specifically targeted at speaker networks, aligning electrical characteristics with common audio crossover requirements.
• Compact radial can — 10 × 20 mm package with 5 mm lead spacing enables compact through‑hole layouts while retaining robust mechanical mounting.
• Measured leakage and loss — Specified leakage current and low tan δ at audio frequencies support sustained performance in crossover and filter circuits.
• Ripple endurance for audio use — Rated ripple current of 480 mArms at the characteristic frequency provides headroom for real‑world audio ripple and transient currents.
• Wide operating temperature — –40 °C to +85 °C range supports typical consumer and professional audio operating environments.
• Regulatory compliance — RoHS compliance supports environmentally conscious designs and regulatory requirements.
