Key Features

• Capacitance and Voltage — 680 µF rated capacitance at 200 V for bulk energy storage and smoothing in DC link and filter circuits.
• Long‑life Endurance — Specified to withstand 5000 hours of rated ripple current at 105°C, supporting longevity in high‑temperature environments.
• Temperature Range — Operates across −25°C to +105°C to accommodate elevated‑temperature power electronics applications.
• Ripple Current Performance — Rated ripple current of 1.87 A at 120 Hz and 2.805 A at 50 kHz to handle both low‑ and high‑frequency switching stress.
• Leakage Current Specification — Leakage behavior defined by I ≤ 3√CV (μA) after rated voltage for 5 minutes at 20°C; datasheet table lists a leakage current value of 1.10 mA for this part.
• Package and Mounting — Radial can, snap‑in terminal type for secure PCB installation and mechanical stability in through‑hole assemblies.
• Polarized with ±20% Tolerance — Polarized capacitor with capacitance tolerance of −20% to +20% at 120 Hz, 20°C for predictable filtering performance.
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• General Inverter Rectifiers — Provides DC smoothing and bulk storage in rectifier stages for inverter systems.
• Switching Power Supplies — Supports output filtering and energy buffering in switched‑mode power supplies subjected to sustained ripple currents.
• General Purpose Power Filtering — Used where high capacitance and reliable endurance at elevated temperature are required for smoothing and decoupling.

Unique Advantages

• High stored energy at 200 V: 680 µF capacitance enables substantial bulk energy capacity for DC link and smoothing duties.
• Extended high‑temperature life: Rated for 5000 hours under rated ripple at 105°C, reducing maintenance and replacement frequency in hot operating environments.
• Strong ripple handling across frequencies: Specified ripple currents of 1.87 A (120 Hz) and 2.805 A (50 kHz) accommodate both low‑ and high‑frequency switching profiles.
• Secure, serviceable mounting: Snap‑in terminal and radial can package simplify through‑hole assembly while providing robust mechanical retention.
• Documented leakage limits: Leakage current defined by I ≤ 3√CV (μA) after rated voltage application, with part‑specific leakage listed at 1.10 mA in the datasheet table.
• Regulatory compliance: RoHS compliance supports use in designs targeting restricted‑substance conformance.
