Key Features

• Capacitance & Voltage — 82 µF rated capacitance with a 450 V rated voltage for high-voltage DC applications.
• Polarized Radial-Lead Package — Radial lead, can-style construction for through-hole mounting and secure mechanical connection.
• Operating Temperature & Endurance — Rated for −40 °C to +105 °C with a specified lifetime of 2000 hours at 105 °C under rated DC bias plus rated ripple current.
• Ripple Current Performance — Rated ripple current of 730 mA at 120 Hz and 1.095 A at 10 kHz, supporting smoothing and decoupling under AC ripple conditions.
• Loss Angle (tan δ) — Maximum tan δ of 0.20 at the 450 V rating (measured at 120 Hz, 20 °C), indicating the dielectric loss limits for design calculations.
• Leakage Current Specification — Leakage current after 1 minute at 20 °C is specified as not more than 0.04CV+100 (µA), enabling predictable bias-related leakage behavior.
• Size — Compact dimensions (L: 5 × D: 1.25 cm) for space-constrained boards while maintaining high-voltage capability.
• Tolerance — Capacitance tolerance of −20% to +20% (±20% at 120 Hz, 20 °C) for predictable performance in bulk energy and filtering roles.

Typical Applications

• High-Voltage Power Supplies — Provides bulk energy storage and smoothing for DC rails up to 450 V, leveraging its rated voltage and ripple-handling capability.
• Power Conversion — Useful for DC link and filtering stages in compact inverters and converters where a miniature high-voltage capacitor is required.
• Industrial Electronics — Suited for general-purpose high-voltage smoothing and decoupling in industrial control and power-management circuits that operate across −40 °C to +105 °C.

Unique Advantages

• High-Voltage Capability: 450 V rating enables use in circuits with elevated DC bus voltages without requiring larger components.
