• Voltage rating — 25 V working voltage suitable for typical audio supply rails.
• Package & mounting — Radial lead, aluminum can; physical size φ10 × 12.5 mm with 5.0 mm lead spacing (lead spacing tolerance ±0.5 mm).
• Temperature and endurance — Operating range −55 °C to 105 °C with endurance specified as 1000 hours at 105 °C.
• Ripple current capability — Low-frequency ripple current 380 mA and high-frequency ripple current 1710 mA as specified for this part.
• Loss and leakage — Tangent of loss angle (tan δ) 0.18 (measured at 120 Hz, 20 °C); leakage current 352.5 µA after 1 minute and 117.5 µA after 2 minutes (at rated voltage, 20 °C).
• Polarized design — Polarized capacitor suitable for DC electrolytic applications.
• Quality and compliance — AEC-Q200 rating listed in product specifications and RoHS compliant.
• Packaging options — Available in bulk (no terminal forming) or bag packing.

Typical Applications

• General audio equipment — Designed for smoothing and decoupling in audio electronics where a compact, radial-lead electrolytic capacitor is required.
• Miniature audio devices — Small form-factor audio modules and PCBs benefiting from the capacitor's compact φ10 × 12.5 mm footprint.
• Audio assemblies and modules — Use in assemblies that require sustained operation across a wide temperature range and defined endurance at elevated temperature.

Unique Advantages

• Compact radial-lead form factor: φ10 × 12.5 mm can and 5 mm lead spacing reduce PCB area while preserving needed capacitance for audio circuits.
• Wide operating temperature: Rated from −55 °C to 105 °C to support audio equipment exposed to varied environmental conditions.
• Specified endurance at high temperature: 1000 hours at 105 °C provides predictable long-term performance for thermal-stressed designs.
• High ripple current handling: Defined low- and high-frequency ripple current ratings support filtering and decoupling across audio-relevant frequency ranges.
• Measurable loss and leakage characteristics: tan δ (0.18 at 25 V, 120 Hz) and specified leakage currents (352.5 µA after 1 minute, 117.5 µA after 2 minutes) allow precise margining in power designs.
• Quality and regulatory compliance: AEC-Q200 listing and RoHS compliance support reliability and regulatory requirements documented in the part specifications.
