This part supports continuous operation from −25°C to +105°C, offers a rated endurance of 3000 hours at 105°C, and is supplied in tray packing for mass production use.

Key Features

• Capacitance & Tolerance — 82 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C for predictable energy storage and decoupling.
• High Voltage Rating — 400 V rated voltage suitable for higher-voltage power circuits where robust DC bus capacitance is required.
• Snap-in Radial Package — Snap-in terminal type in a radial can (φ25 × 20 mm) for secure board mounting and reliable mechanical retention in assemblies.
• Ripple Current Capability — 700 mA rated ripple at 120 Hz (low frequency) and 1.001 A rated ripple at 50 kHz (high frequency) to support AC ripple and switching workloads within specified limits.
• Leakage Current — Specified leakage current of 540 µA after voltage application, enabling predictable standby and leakage behavior in designs.
• Operating Range & Endurance — Specified for −25°C to +105°C operation with 3000 hours lifetime at 105°C, supporting sustained high-temperature use within the rated envelope.
• Polarized Device — Polarized electrolytic design for DC applications requiring correct polarity handling.
• Production & Packaging — Tray-packed and indicated for mass production deployment.

Typical Applications

• General-purpose power circuits — Provides bulk capacitance and smoothing in higher-voltage DC circuits where 400 V rating and 82 µF capacitance are required.
• Power supply filtering — Supports ripple handling with specified ripple currents at both low and high frequencies for filtering and decoupling tasks.
• Industrial and equipment electronics — Suitable for general-purpose use in equipment that operates within −25°C to +105°C and requires proven endurance at elevated temperatures.

Unique Advantages

• High-voltage bulk capacitance: 82 µF at 400 V delivers substantial energy storage in a compact, snap-in can for DC bus and smoothing applications.
• Dual-frequency ripple performance: Rated ripple figures at 120 Hz and 50 kHz give designers clear, verifiable limits for both low- and high-frequency ripple scenarios.
• Measured leakage spec: The 540 µA leakage current value provides predictable quiescent behavior for power budgeting and safety margin calculations.
• Temperature endurance: 3000 hours at 105°C specification supports long-term reliability in thermally demanding installations.
• Snap-in mechanical retention: Radial snap-in package simplifies board assembly and secures the capacitor in mechanical vibration and handling environments.
• Mass-production-ready packaging: Tray packing facilitates efficient handling and integration into automated assembly lines.
