Key Features

• Capacitance & Voltage: 47 µF nominal capacitance with a rated voltage of 160 V and capacitance tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• High Ripple Current Capability: Rated low‑frequency ripple current of 375 mA at 120 Hz and high‑frequency ripple current of 750 mA at 100 kHz to support demanding power filtering applications.
• Long Endurance: Load‑life rated for 8000 hours at 105°C, providing stable performance over extended operating periods when used within specified limits.
• Electrical Loss Characteristics: Tangent of loss angle (tan δ) specified at 0.20 (measurement condition: 20°C, 120 Hz) for predictable ESR behavior in circuit design.
• Leakage Current: Specified leakage current of 400.8 µA (measured after 1 minute at 20°C), aiding in power‑budget and standby calculations.
• Compact Radial Package: φ10 × 20 mm aluminum can with radial leads (5.0 mm spacing, ±0.5 mm), available in bulk or bag packing for through‑hole assembly.
• Wide Operating Temperature: Rated for −40°C to +105°C to cover a broad range of industrial temperature environments.
• RoHS Compliant: Conforms to RoHS requirements for environmental compliance.

Typical Applications

• Power Supplies: Bulk filtering, smoothing and decoupling in medium‑voltage power supply rails where 160 V rating and high ripple capability are required.
• Ballast Circuits: Energy storage and ripple handling in ballast applications, leveraging the part’s ripple current rating and long endurance at elevated temperature.
• General‑Purpose Electronic Circuits: Through‑hole radial mounting for a variety of industrial and commercial electronic designs that need compact, polarized aluminum electrolytic capacitance.

Unique Advantages

• Compact footprint with substantial capacitance: φ10 × 20 mm case provides 47 µF at 160 V, balancing size and energy storage for space‑constrained boards.
• Designed for sustained ripple: 375 mA at 120 Hz and 750 mA at 100 kHz ripple ratings reduce thermal stress and improve reliability in continuous‑load applications.
• Proven long life at elevated temperature: 8000 hours endurance at 105°C supports designs requiring predictable long‑term performance.
• Measured loss characteristics: tan δ = 0.20 (20°C, 120 Hz) offers predictable dissipation for thermal and ESR budgeting in power designs.
• Manufacturing‑friendly radial format: Standard 5.0 mm lead spacing and bulk/bag packing options simplify through‑hole assembly and inventory handling.
• Regulatory compliance: RoHS conformity helps meet environmental requirements for commercial and industrial products.
