Designed for general-purpose power filtering and switching power supply circuits, this capacitor delivers a combination of high voltage capability, elevated operating temperature rating, and long endurance for demanding applications. Status: End Of Life.

Key Features

• Capacitance & Voltage: 220 µF nominal capacitance with a 160 V rated voltage and ±20% tolerance for power rail and energy-storage applications.
• Low-loss Performance: tan δ = 0.15 (DF) measured at 20°C and 120 Hz, supporting stable AC performance in filtering and decoupling roles.
• High Ripple Handling: 500 mA ripple current at 120 Hz (low frequency) and 800 mA at 10 kHz (high frequency), enabling effective smoothing in both line- and switch-frequency domains.
• Long Endurance: Rated for 3000 hours at 105°C under DC bias plus rated ripple current, providing extended service life in elevated-temperature environments.
• Temperature Range: Operating from −40°C to 105°C for wide environmental tolerance in industrial and commercial equipment.
• Compact Radial Package: φ20 × 31 mm can, radial lead mounting with 10 mm ±0.5 mm lead spacing; available in bulk or bag packing for straightforward through-hole assembly.
• Leakage Current: Specified leakage current of 1508 µA (measured after 1 minute at 20°C), enabling predictable standby and leakage behavior in designs.
• RoHS Compliant: Manufactured to meet RoHS requirements for environmental compliance.

Typical Applications

• Switching Power Supplies: Bulk filtering and output smoothing where high voltage rating and ripple current capability are required.
• Power Conversion Modules: Energy storage and decoupling in DC–DC converters and power-management circuits that operate across a wide temperature range.
• Industrial & Commercial Electronics: General-purpose power filtering for control systems and instrumentation benefiting from long endurance at elevated temperatures.

Unique Advantages

• High Voltage Capability: 160 V rating supports higher-voltage rails without requiring series stacking or additional parts.
• Designed for Switching Environments: Measured ripple ratings at both 120 Hz and 10 kHz provide explicit guidance for line- and high-frequency switching applications.
• Extended High-Temperature Life: 3000 hours at 105°C gives predictable lifetime performance in thermally stressed designs.
• Compact Footprint with Through-Hole Robustness: Small φ20 × 31 mm can and radial leads simplify board-level assembly while maintaining physical durability.
• Controlled Dielectric Loss: Specified tan δ supports designers in predicting AC losses and thermal rise under ripple conditions.
