Key Features

• Conductive polymer solid electrolyte — Solid electrolyte construction for low ESR and stable performance.
• Capacitance and voltage — 47 µF capacitance rated at 25 V with ±20% tolerance at 120 Hz, 20°C.
• Low ESR — 24 mΩ equivalent series resistance measured at 100 kHz, 20°C, supporting efficient power delivery and low loss.
• High ripple current capability — Rated ripple currents of 360 mA at 120 Hz and 3.6 A at 300 kHz enable handling of significant AC ripple in power circuits.
• Extended load life — Load life specified at 2000/5000 hours at 105°C (endurance test conditions at rated voltage), supporting long-term reliability under elevated temperature stress.
• Wide operating temperature range — −55°C to +105°C for deployment across varied thermal environments.
• Radial lead, compact package — Radial, can-style package with 3.5 mm lead spacing and dimensions L: 1.15 × D: 0.8 cm for through-hole mounting and compact board layouts.
• Compliance and solderability — Lead-free flow soldering condition correspondence and RoHS directive compliance (2011/65/EU, (EU) 2015/863).
• Polarized — Standard polarized capacitor for correct polarity installation in circuits.

Typical Applications

• General-purpose power filtering — Use where low ESR and significant ripple-current tolerance are required for smoothing and decoupling.
• Decoupling and local energy storage — Suitable for stabilizing rail voltages and supporting transient loads in compact through-hole designs.
• Board-mounted power modules — Radial can package fits through-hole assemblies that require compact, reliable capacitors with lead spacing of 3.5 mm.

Unique Advantages

• Low-impedance performance: 24 mΩ ESR at 100 kHz reduces voltage ripple and power loss in high-frequency circuits.
• High ripple-current handling: Rated ripple currents up to 3.6 A at 300 kHz enable the capacitor to manage demanding AC stress in power applications.
• Thermal and lifetime resilience: Operates from −55°C to +105°C and specified for 2000/5000 hours at 105°C for extended reliability under elevated temperatures.
• Compact through-hole form factor: Radial, can-style package with 3.5 mm lead spacing and small footprint simplifies integration into space-constrained PCBs.
• Regulatory and assembly readiness: RoHS-compliant materials and lead-free flow soldering correspondence support modern manufacturing and environmental requirements.
