It delivers low ESR and high ripple-handling capability in a low-profile φ8×8 package, and is offered in mass-production quantities.

Key electrical and mechanical characteristics include 180 µF capacitance at 16 V rated voltage, ESR of 12 mΩ measured at 20°C/100 kHz, a wide operating temperature range of -55°C to 105°C, and an endurance rating up to 5000 hours at 105°C.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a rated voltage of 16 V and capacitance tolerance of -20% to +20%.
• Low ESR — 12 mΩ ESR specified at 20°C/100 kHz, supporting efficient high-frequency performance and low heat generation.
• High Ripple Current Capability — Rated ripple current of 500 mA at 120 Hz and 5 A at 300 kHz, with frequency coefficients provided for design use.
• Temperature & Endurance — Operating temperature range from -55°C to +105°C and a life/endurance rating of 5000 hours at 105°C.
• Leakage & Loss Angle — Leakage current specified (576 µA) and tan δ (DF) of 0.12 measured at 20°C, 120 Hz, 16 V.
• Compact Radial Package — Low-profile φ8×8L can with 3.5 mm lead spacing (±0.5 mm tolerance) for compact board layouts; radial lead type supports lead-free flow soldering conditions.
• Compliance — RoHS compliant.

Typical Applications

• General-Purpose Electronics — Suitable for a wide range of general-purpose circuits where stable capacitance and low-profile packaging are required.
• High-Frequency Power Filtering — With 12 mΩ ESR at 100 kHz and rated ripple current up to 5 A at 300 kHz, the part supports high-frequency ripple suppression and decoupling needs.
• Thermally Demanding Environments — Rated for operation from -55°C to 105°C and endurance up to 5000 hours at 105°C, making it applicable where extended thermal stress handling is required.

Unique Advantages

• Low-profile design: The φ8×8L package provides compact board footprint without sacrificing capacitance.
• High ripple tolerance: 5 A ripple capacity at high frequency reduces stress on the capacitor in high-speed power applications.
• Low ESR for efficiency: 12 mΩ ESR at 100 kHz minimizes I²R losses and improves power-conversion efficiency.
• Robust thermal endurance: 5000-hour life at 105°C supports longer operational lifetimes in hot environments.
• Radial-lead convenience: 3.5 mm lead spacing (±0.5 mm) and lead-free flow soldering compatibility simplify through-hole assembly processes.
• Regulatory compliance: RoHS compliance supports use in regulated markets and product lines.
