UCA2D470MHD

The UCA2D470MHD is a miniature, radial-lead aluminum electrolytic capacitor designed for high ripple current and long operational life. It delivers 47 µF at a rated voltage of 200 V in a compact radial can package suited for power-handling circuits.

Typical use cases include power supply and ballast applications where compact size, sustained ripple capability, and extended endurance are required. The device is RoHS compliant and built to operate across a wide temperature range.

Key Features

• Capacitance and Voltage: 47 µF nominal capacitance with a rated voltage of 200 V and ±20% tolerance at 120 Hz, 20°C.
• High ripple current capability: Rated ripple current of 780 mA at 105°C and 100 kHz, and 390 mA at 120 Hz (lower-frequency rating).
• Long life endurance: Rated for 12,000 hours at 105°C under DC bias plus rated ripple current.
• Low-loss performance: Tangent of loss angle (tan δ) max. 0.15 measured at 120 Hz, 20°C.
• Leakage current: Typical specification of 476 µA after 1 minute at rated voltage and 20°C.
• Temperature range: Operates from −25°C to +105°C.
• Compact radial package: Radial lead, can-style package with 5 mm lead spacing and dimensions approximately L: 2.0 cm × D: 1.25 cm.
• Regulatory compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies: Bulk or filtering capacitor in power supply circuits where high ripple handling and long life at elevated temperatures are required.
• Ballasts: Designed for ballast applications that demand sustained ripple endurance and reliable performance over extended periods.
• General Purpose Electronics: General-purpose radial-lead use in electronic equipment requiring a compact 200 V, 47 µF electrolytic solution.

Unique Advantages

• High ripple tolerance: 780 mA at 100 kHz (105°C) provides headroom for high-frequency ripple environments and demanding power circuits.
• Extended operational life: 12,000-hour endurance at 105°C supports long-term reliability in thermal-stressed applications.
• Compact footprint: Small can-style radial package with 5 mm lead spacing and compact L×D footprint helps conserve board area in dense designs.
• Predictable AC loss behavior: Low tan δ (0.15 at 120 Hz, 20°C) gives predictable dissipation characteristics for thermal and ripple budgeting.
• Regulatory readiness: RoHS compliance simplifies environmental qualification for industrial and commercial products.
