• Voltage Rating: Rated for 16 V DC operation.
• High Ripple Current: Low-frequency ripple current of 3.57 A at 120 Hz and high-frequency ripple current of 4.2 A at 10 kHz, supporting demanding AC superimposed conditions.
• Low Impedance: Impedance specified at 30 mΩ, supporting effective high-current filtering and reduced voltage droop under load.
• Reliability / Lifetime: Endurance specified as 10,000 hours at 105°C when subjected to rated DC bias plus rated ripple current; capacitance change and tan δ limits defined per series performance.
• Temperature Range: Operates from −40°C to +105°C to accommodate a wide range of environmental conditions.
• Mechanical / Mounting: Radial lead can package, size φ16 × 35.5 mm length, lead spacing 7.5 mm (±0.5 mm), suitable for through-hole PCB mounting.
• Leakage and Loss: Specified leakage current of 1312 µA and tan δ (DF) of 0.29 measured at 20°C, 120 Hz, enabling predictable loss and leakage behavior.
• Packaging & Compliance: Available in bulk (no terminal forming) or bag packing and RoHS compliant.

Typical Applications

• Power Supply Filtering — Provides bulk smoothing and ripple handling where 8.2 mF at 16 V and multi-amp ripple capability are required.
• DC Link and Energy Storage — Suitable for general-purpose designs that need compact bulk capacitance with low impedance to support transient currents.
• General Electronic Equipment — Fits through-hole assemblies requiring long-life capacitors rated for −40°C to 105°C and 10,000 hours endurance at elevated temperature.

Unique Advantages

• High Ripple Current Capacity: Delivers 3.57 A at 120 Hz and 4.2 A at 10 kHz to handle sustained AC stress without excessive heating.
• Compact Radial Can: φ16 × 35.5 mm form factor with 7.5 mm lead spacing balances board space and bulk capacitance for through-hole designs.
• Long Endurance at Elevated Temperature: Rated for 10,000 hours at 105°C, offering predictable life performance under high-temperature operating conditions.
• Low Impedance: 30 mΩ impedance supports effective filtering and reduced voltage ripple in power stages.
• Wide Operating Temperature: −40°C to +105°C specification supports a broad range of environmental conditions.
• Regulatory Compliance: RoHS compliant for use in assemblies that require restriction of certain hazardous substances.
