UCA2D680MHD

The UCA2D680MHD is a miniature, radial‑lead aluminum electrolytic capacitor rated 68 µF at 200 V. It is designed for through‑hole power applications where high ripple handling, compact footprint, and long operational life at elevated temperature are required.

Key use cases include power supply filtering and ballast applications. The device offers a high rated ripple current and long endurance at 105°C, and is RoHS compliant. Note: this product is scheduled to be discontinued and is not recommended for new designs.

Key Features

• Capacitance & Voltage — 68 µF rated capacitance with a 200 V DC rating and ±20% tolerance at 120 Hz, 20°C.
• High Ripple Current — Rated ripple current of 950 mArms at 105°C and 100 kHz (475 mA at 120 Hz), supporting demanding AC superimposed workloads.
• Long Endurance at Elevated Temperature — Designed for a load life of 12,000 hours at +105°C under rated DC bias plus rated ripple current.
• Low Loss Characteristic — Tangent of loss angle (tan δ) specified at 0.15 (measurement at 120 Hz, 20°C) for predictable dissipation behavior.
• Temperature Range — Category operating temperature from −25°C to +105°C for extended environmental capability.
• Construction & Mounting — Polarized radial‑lead can package for through‑hole assembly; lead spacing 5.0 mm and case footprint L: 2.5 × D: 1.25 cm.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies — Bulk filtering and smoothing where high ripple current and elevated‑temperature endurance are required.
• Ballasts — Suitable for ballast circuits that demand sustained ripple performance and long life at 105°C.
• General Purpose Through‑Hole Power Electronics — Useful in industrial and commercial through‑hole assemblies needing polarized electrolytic capacitance.

Unique Advantages

• High ripple capability: 950 mArms at 105°C/100 kHz lets designs handle significant AC superposition without exceeding the rated ripple spec.
• Extended high‑temperature life: 12,000 hours at 105°C provides predictable end‑of‑life characteristics for power applications.
• Compact radial package: Small can footprint (L: 2.5 × D: 1.25 cm) and radial leads simplify through‑hole assembly and layout density.
• Measured dissipation data: Specified tan δ (0.15 at 120 Hz, 20°C) supports thermal and ESR budgeting in designs.
• Regulatory assurance: RoHS compliance supports restricted‑substance requirements for many commercial applications.

Why Choose UCA2D680MHD?

UCA2D680MHD is positioned for engineers who need a compact, high‑ripple, long‑life aluminum electrolytic capacitor for through‑hole power designs. The combination of 200 V rating, 68 µF capacitance, and a high rated ripple current at elevated temperature makes it suitable for demanding filtering and ballast use cases where predictable endurance is important.

While the part is RoHS compliant and built to provide consistent dissipation and endurance characteristics, please note it is scheduled for discontinuation and is therefore best suited for legacy support or replacement scenarios rather than new designs.
