UCS2E100MPD

The UCS2E100MPD is a Nichicon UCS series aluminum electrolytic capacitor: a polarized, radial‑lead can designed for high ripple current and long operational life. This 10 µF, 250 V part delivers compact energy storage and ripple handling for high‑voltage DC rails and ballast or power‑supply circuits.

Built for elevated‑temperature operation, the part is rated for –40°C to +105°C and is RoHS compliant, making it suitable for equipment that requires sustained performance under thermal stress.

Key Features

• Electrical: 10 µF, 250 V — Nominal capacitance of 10 µF with a rated voltage of 250 V and capacitance tolerance of ±20% (at 120 Hz, 20°C).
• High ripple capability — Designed for high ripple handling: 175 mA at 120 Hz (low frequency) and 350 mA at 100 kHz (high frequency). Frequency coefficients (series data) show 0.50 at 120 Hz and 1.00 at 100 kHz for ripple scaling.
• Long elevated‑temperature life — Rated lifetime of 8000 hours at +105°C for the specified part; the UCS series supports load life in the 8000–10000 hour range at +105°C.
• Wide operating temperature — Operates from –40°C to +105°C to accommodate demanding thermal environments.
• Radial lead, compact package — Radial can package with 5 mm lead spacing and size approximately L: 2 cm × D: 1 cm for space‑conscious board layouts.
• Polarized with controlled leakage — Polarized electrolytic design; series leakage-current specification: after 1 minute at rated voltage and 20°C, leakage current ≤ 0.04CV + 100 µA (where C = µF, V = rated voltage).
• RoHS compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supplies — Bulk smoothing and high‑voltage rail decoupling where compact size and high ripple endurance are required.
• Ballasts and lighting drivers — Suited for ballast circuits that demand stable performance under continuous AC‑derived ripple and elevated temperature.
• Industrial power conversion — High‑voltage sections of converters and power modules that need reliable, long‑life capacitive filtering.

Unique Advantages

• Compact footprint with high voltage rating — 10 µF at 250 V in a small radial can enables space savings on high‑voltage boards.
• Demonstrated ripple performance — Specified ripple currents at both 120 Hz and 100 kHz provide predictable behavior across common power‑conversion frequencies.
• Designed for long life at elevated temperature — 8000 hours at +105°C supports durable operation in thermally stressed applications.
• Clear leakage specification — Leakage‑current formula allows engineers to calculate expected leakage for power‑budget and reliability planning.
• Radial lead convenience — Through‑hole radial mounting simplifies mechanical retention and rework in prototyping and production.
• Regulatory compliance — RoHS compliance supports environmental and supply‑chain requirements.
