UCA2E100MPD

The UCA2E100MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UCA series. It is a polarized, standard-type component designed for general-purpose power applications requiring a compact, high-voltage capacitor with elevated ripple handling and extended life.

Key electrical characteristics include 10 µF capacitance at a 250 V rating, a temperature range of −25 °C to 105 °C, and a rated life of 10,000 hours at 105 °C. Status: End Of Life — products are scheduled to be discontinued and are not recommended for new designs.

Key Features

• Capacitance & Voltage — 10 µF nominal capacitance with a 250 V rated voltage and capacitance tolerance of −20% to +20%.
• High ripple capability — Specified low-frequency ripple current 150 mA (120 Hz) and high-frequency ripple current 300 mA (100 kHz) to support power-supply and ballast applications.
• Long life at elevated temperature — Rated endurance of 10,000 hours at 105 °C under DC bias plus rated ripple conditions for φD = 10 mm cases.
• Controlled dissipation factor — tan δ (DF) of 0.15 measured at 20 °C, 120 Hz for stable AC characteristics.
• Leakage current — Specified leakage current of 200 µA (measured after 1 minute at 20 °C under rated voltage conditions).
• Compact radial can — Physical size φ10 × 20 mm with radial lead mounting (lead spacing 5.0 mm, tolerance ±0.5 mm), suitable for through-hole assemblies.
• Packaging options — Supplied in bulk (no terminal forming) or bag packing.
• Environmental compliance — RoHS compliant.

Typical Applications

• Power Supplies — Bulk filtering and decoupling in general-purpose power-supply circuits where 250 V rating and compact size are required.
• Ballasts — Designed to handle the ripple and thermal demands typical of ballast applications.
• General Purpose Power Circuits — Through-hole radial-lead format for legacy boards, bench equipment, and repair applications.

Unique Advantages

• High-voltage capability: 250 V rating supports a broad range of power-system designs without upsizing the capacitor.
• Compact footprint: φ10 × 20 mm can body provides a small package for space-constrained through-hole layouts.
• Enhanced ripple handling: Specified ripple currents at 120 Hz and 100 kHz help manage AC stress in power and ballast circuits.
• Extended operating life at elevated temperature: 10,000 hours at 105 °C enables reliable operation under sustained thermal load for maintenance and repair use cases.
• Clear electrical limits: Specified tan δ and leakage current values allow predictable selection and validation in design and test.
• RoHS compliant: Meets RoHS requirements for environmentally managed programs.

Why Choose UCA2E100MPD?

UCA2E100MPD delivers a focused combination of 250 V capability, compact φ10 × 20 mm radial-can packaging, and defined ripple and life specifications that make it suitable for replacement, repair, and general-purpose power applications where a polarized electrolytic capacitor is required. Its specified TAN δ, leakage current, and ripple ratings enable straightforward electrical evaluation and reliable use within the declared temperature and life limits.

While this part is End Of Life and scheduled for discontinuation, it remains a clear, specification-driven option for existing designs and service inventories that require a known, documented performance profile from the Nichicon UCA series.
