UCA2E101MHD

The UCA2E101MHD is a miniature, radial-lead aluminum electrolytic capacitor designed for high ripple current and long operational life. It provides 100 µF capacitance at a 250 V rating in a compact can-style radial package, suited for general-purpose power applications such as power supplies and ballasts.

Key value propositions include high ripple handling (1.4 A at 100 kHz), a long rated life of 12,000 hours at 105°C, and RoHS compliance. Note: this part is scheduled to be discontinued and is not recommended for new designs.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with ±20% tolerance at 120 Hz, rated for 250 V operation.
• High Ripple Current — Rated ripple current of 1.4 A at 100 kHz (high frequency) and 700 mA at 120 Hz (low frequency), enabling robust filtering in high-frequency power circuits.
• Long Life / Endurance — Load-life rated for 12,000 hours at +105°C under DC bias plus rated ripple current, with specified limits on capacitance change, tan δ, and leakage current after test.
• Electrical Characteristics — Tangent of loss angle (tan δ) 0.15 (max) at 120 Hz, 20°C; leakage current 1,100 µA (per 0.04·C·V + 100 μA formula) after 1 minute at 20°C.
• Temperature Range — Operates from −25°C to +105°C for broad thermal compatibility in power applications.
• Package & Mounting — Radial lead, can-style package with 7.5 mm lead spacing and compact dimensions of 3.05 × 1.6 cm (L × D) for through-hole assemblies.
• Environmental Compliance — RoHS compliant.
• Polarized — Standard polarized electrolytic construction for DC filtering and energy-storage tasks.

Typical Applications

• Power Supplies — Bulk filtering and high-frequency decoupling where 250 V capability and strong ripple handling are required.
• Ballasts — Intended for ballast circuits as noted in the product series specification, providing stable capacitance and endurance at elevated temperatures.
• General-Purpose High-Voltage Filtering — Through-hole radial package suited for repair, prototyping, or legacy board designs that require a compact 250 V electrolytic.

Unique Advantages

• High ripple capability: 1.4 A at 100 kHz and 700 mA at 120 Hz allow reliable operation in high-frequency switching environments.
• Extended operational life: 12,000-hour endurance at 105°C supports designs requiring sustained high-temperature operation.
• Compact, through-hole form factor: Small can dimensions (3.05 × 1.6 cm) and 7.5 mm lead spacing simplify integration into existing through-hole boards and legacy layouts.
• Predictable electrical behavior: Specified tan δ (0.15) and a clear leakage-current specification (0.04·C·V + 100 μA) make it straightforward to model performance in power designs.
• RoHS compliance: Environmentally compliant for regions and programs requiring restricted-substance adherence.

Why Choose UCA2E101MHD?

The UCA2E101MHD positions itself as a compact, high-voltage electrolytic solution for engineers who need dependable ripple performance and long life in through-hole power applications. Its combination of 250 V rating, strong high-frequency ripple capability, and 12,000-hour endurance at 105°C makes it suitable for power supplies, ballast circuits, and general-purpose high-voltage filtering on legacy or service-oriented boards.

Choose this part when you require verifiable electrical characteristics—tolerance, tan δ, leakage current, and ripple current—backed by Nichicon's UCA series specifications. Keep in mind the part is scheduled for discontinuation and is therefore best suited for maintenance, repair, or existing-design continuity rather than new product introductions.
