UCA2C101MHD

The UCA2C101MHD is a miniature-sized, radial-lead aluminum electrolytic capacitor designed for general-purpose power applications. It delivers 100 µF capacitance at a 160 V rating in a compact φ16 × 25 mm can, with polarized radial leads and 7.5 mm lead spacing.

Engineered for high ripple handling and extended endurance, this part is specified for 1.28 A ripple at 100 kHz (105 °C) and a rated lifetime of 12,000 hours at 105 °C. The device is RoHS compliant and supplied in bulk (no terminal forming). Note: this product is scheduled for discontinuation and is not recommended for new designs.

Key Features

• Electrical Performance — 100 µF capacitance with ±20% tolerance and a rated voltage of 160 V, suitable for polarized DC applications.
• High Ripple Capability — Rated ripple current of 1.28 A at 100 kHz and 105 °C; frequency coefficient data supports use across low- and high-frequency ripple environments.
• Long Life Endurance — Specified for 12,000 hours at 105 °C under DC bias plus rated ripple current, with post-test limits of capacitance change within ±20% and leakage current at or below initial specified values.
• Thermal Range — Operating temperature range from −25 °C to +105 °C to cover a wide range of thermal environments.
• Low Loss Characteristic — Tangent of loss angle (tan δ) of 0.15 at 120 Hz and 20 °C for the 160 V rating, supporting efficient energy handling.
• Compact Radial Can Package — 16 mm diameter × 25 mm length can with 7.5 mm lead spacing and radial lead mounting for through-hole PCB designs; supplied in bulk (no terminal forming).
• Leakage Current — Specified leakage current of 740 µA (as provided for this part) after 1 minute at 20 °C.
• Compliance — RoHS compliant.

Typical Applications

• Power Supplies — Bulk and smoothing capacitor in power supply rails where high ripple current capability and long-life endurance are required.
• Ballasts and Lighting Drivers — Suited for ballast-type circuits that demand sustained ripple performance at elevated temperatures.
• General Purpose Power Electronics — Through-hole radial mounting for industrial and consumer assemblies requiring compact high-voltage capacitors.

Unique Advantages

• High Ripple Endurance: Rated 1.28 A at 100 kHz and 105 °C, enabling stable operation under continuous AC superimposed on DC.
• Extended Lifecycle: 12,000-hour rating at 105 °C provides predictable long-term behavior for deployed systems.
• Compact High-Voltage Form Factor: 160 V rating in a φ16 × 25 mm can offers a space-efficient solution for through-hole designs.
• Low Loss Operation: tan δ = 0.15 at 120 Hz (160 V) helps minimize dissipation in filtering and decoupling roles.
• Industry-Ready Compliance: RoHS compliance supports environmental directive requirements for assembled products.
• Practical Packaging: Supplied in bulk (no terminal forming), easing stocking and high-volume assembly workflows for compatible production lines.

Why Choose UCA2C101MHD?

The UCA2C101MHD positions itself as a compact, high-voltage electrolytic solution for designs that require sustained ripple handling and long thermal endurance. With a 160 V rating, 100 µF capacitance, and a 12,000-hour life at 105 °C, it is targeted at engineers specifying durable bulk and smoothing capacitors for power supplies, ballasts, and general-purpose power electronics where through-hole mounting is preferred.

This part is appropriate for teams prioritizing reliable long-term performance and clear electrical limits (leakage, tan δ, ripple current) in a small radial can. Keep in mind the product is scheduled for discontinuation and is not recommended for new designs; it remains a viable option for maintaining or repairing existing designs that call for this exact specification set.
