Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High‑Temperature Endurance — Rated for 2000 hours of operation at 105°C when biased with DC plus rated ripple current, with defined post-test limits for capacitance, tan δ and leakage.
• Ripple Current Capability — Specified ripple handling of 1.7 A (120 Hz) and 2.04 A (10 kHz), supporting AC ripple currents encountered in power circuits.
• Electrical Loss & Leakage — Tangent of loss angle (tan δ) ≤ 0.20 at 120 Hz and 20°C; leakage current defined by I ≤ 3√(C·V) µA after 5 minutes’ application of rated voltage.
• Safety & Robustness — Pressure relief vent and improved safety design for abnormally excessive voltage conditions to limit hazardous outcomes under abnormal stress.
• Mounting & Package — Snap‑in terminal, radial can construction in a φ30 × 40 mm form factor; supplied in tray packing for mass production.
• Temperature Range — Specified operating range from −25°C to +105°C.
• Environmental Compliance — RoHS compliant in accordance with the directive cited in the product documentation.

Typical Applications

• General Purpose Power Equipment — Bulk capacitance and rated voltage suitable for smoothing and energy storage in general-purpose power designs.
• Voltage‑Fluctuating Environments — Intended for equipment operating where supply voltages vary, leveraging the series’ enhanced safety features for abnormal voltage.
• Industrial Systems — Suitable where long high-temperature lifetime and reliable ripple handling are required for continuous operation.

Unique Advantages

• Extended High‑Temperature Life: 2000 hours at 105°C provides predictable aging and performance over extended high-temperature operation.
• Designed for Abnormal Voltage Tolerance: Safety features including a pressure relief vent and construction designed to limit hazardous failures under excessive voltage conditions.
• High Capacitance at 200 V: 680 µF at a 200 V rating delivers substantial energy storage in a compact snap‑in package for robust power designs.
• Quantified Ripple Performance: Published ripple current values at both low and high frequencies (1.7 A @120 Hz, 2.04 A @10 kHz) allow engineers to size the capacitor against measured ripple loads.
• Clear Electrical Limits: Defined tan δ and leakage current specifications (including the I ≤ 3√CV rule) enable reliable selection and margin analysis.
• Production‑Ready Packaging: Tray packing and mass production availability facilitate BOM planning and assembly throughput.
