UCY2C390MPD

The UCY2C390MPD is a Nichicon UCY series aluminum electrolytic capacitor in a compact radial-lead can, delivering 39 µF capacitance at a 160 V rated voltage. Engineered for high ripple handling and long life, this part is suited to power-supply smoothing, DC bus, and ballast applications where compact size and reliable performance at elevated temperatures are required.

This device combines high-frequency ripple capability, AEC‑Q200 qualification, and a 10,000‑hour endurance at 105°C to support robust designs in demanding environments while remaining RoHS compliant.

Key Features

• Capacitance and Voltage — 39 µF nominal capacitance with a rated voltage of 160 V and capacitance tolerance of −20% to +20%.
• Low Loss Characteristics — tanδ (DF) max 0.20 measured at 20°C, 120 Hz, supporting efficient filtering and lower dissipation in AC applications.
• High Ripple Current Capability — Rated low-frequency ripple current 295 mA at 120 Hz and high-frequency ripple current 590 mA at 100 kHz, with series frequency coefficients applicable across common operating frequencies.
• Long Life Endurance — Rated life of 10,000 hours at 105°C under rated DC bias plus ripple current, with specified recovery to published limits after test conditions.
• Compact Radial Package — φ10 × 16 mm can with 5.0 mm lead spacing (±0.5 mm), radial-lead mounting for through-hole assemblies; available in bulk (no terminal forming) or bag packing.
• Leakage Current — Typical leakage current value provided as 349.6 µA (measured condition per product data).
• Quality and Compliance — AEC‑Q200 qualified and RoHS compliant for use in regulated production environments.

Typical Applications

• Power Supplies — DC filtering and bulk decoupling where 160 V rating and high ripple current capability improve ripple attenuation and thermal performance.
• Ballasts and Lighting Electronics — Smoothing and energy storage in ballast circuits benefiting from the part’s high-frequency ripple handling and long endurance at elevated temperature.
• Automotive Electronics — Suitable for automotive-related designs that require AEC‑Q200 qualified components with extended high-temperature life and robust ripple performance.
• Industrial Control — Power conditioning and transient absorption in industrial control modules where reliability at −40°C to +105°C operating range is required.

Unique Advantages

• High ripple current rating: Enables reduced temperature rise and improved life in applications with significant AC content by supporting 295 mA at 120 Hz and 590 mA at 100 kHz.
• Extended high-temperature life: 10,000 hours at 105°C provides predictable aging and durability for long-term deployments.
• AEC‑Q200 qualification: Supports designs that require industry-recognized qualification for demanding environments.
• Compact footprint: φ10 × 16 mm can with 5 mm lead spacing minimizes board area while providing necessary capacitance and voltage margin.
• RoHS compliant: Meets environmental regulatory requirements for lead-free production.
• Flexible packing: Available in bulk (no terminal forming) or bag packing to match assembly and handling workflows.
