Key electrical and reliability characteristics include a loss tangent (tanδ) of 0.20 (measured at 20°C, 120 Hz), low- and high-frequency ripple handling of 620 mA (120 Hz) and 992 mA (10 kHz), and an endurance rating of 2000 hours at 105°C. Status: End Of Life.

Key Features

• Capacitance & Tolerance — 220 µF nominal with ±20% tolerance (measured at 120 Hz, 20°C).
• Rated Voltage — 315 V DC rating suitable for higher-voltage general-purpose designs.
• Loss Tangent (tanδ) — 0.20 maximum at 20°C, 120 Hz, providing a specified dissipation characteristic for AC conditions.
• Ripple Current Capability — Low-frequency ripple current 620 mA at 120 Hz and high-frequency ripple current 992 mA at 10 kHz, specified per the part data.
• Leakage Current — Specified leakage current of 2872 µA under rated conditions.
• Temperature & Endurance — Operating range −40°C to +105°C with a rated life of 2000 hours at 105°C.
• Package & Mounting — Radial lead, can-style package (φ22 × 50 mm overall), lead spacing 10 mm (±0.5 mm), supplied Bulk (no terminal forming) or Bag packing.
• RoHS Compliance — Manufactured to meet RoHS requirements as noted in product information.
• Polarized Device — Designed for polarized applications; observe polarity in assembly.

Typical Applications

• General-purpose power electronics — Provides bulk capacitance and smoothing where a 315 V, 220 µF polarized capacitor is required.
• Industrial equipment — Suited for designs that require operation across −40°C to +105°C and a specified 2000-hour endurance at elevated temperature.
• Boards with radial mounting — Radial-lead can package and 10 mm lead spacing simplify through-hole placement and assembly in conventional PCB layouts.

Unique Advantages

• High-voltage capability: 315 V rating enables use in higher-voltage, general-purpose circuits requiring substantial capacitance.
• Defined ripple handling: Specified ripple current values at both low (120 Hz) and high (10 kHz) frequencies let designers size thermal and ripple performance precisely.
• Wide operating temperature: −40°C to +105°C range supports applications exposed to broad environmental conditions.
• Long endurance at elevated temperature: 2000 hours at 105°C offers predictable life performance for thermal-stressed designs.
• Compact radial can format: φ22 × 50 mm package with 10 mm lead spacing simplifies through-hole integration and handling.
• RoHS compliant: Conforms to RoHS directive requirements included in the product documentation.
