UCS2W100MHD

The UCS2W100MHD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's UCS series. It delivers a 10 µF capacitance at a 450 V rating in a compact radial can package designed for high-ripple and long-life applications.

Targeted for power supply and ballast applications, this part combines high ripple-current capability and extended endurance at elevated temperature to support robust, high-voltage electronic designs while remaining RoHS compliant.

Key Features

• High Voltage Rating — Rated for 450 V, enabling use in high-voltage sections of power electronics where elevated DC voltage handling is required.
• Capacitance & Tolerance — 10 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C, providing predictable filtering and decoupling behavior.
• High Ripple Current Performance — Capable of 225 mA ripple at 120 Hz and 450 mA at 100 kHz, supporting heavy ripple conditions found in switching power supplies and ballast circuits.
• Long Endurance at Elevated Temperature — Specified lifetime of 10,000 hours at +105°C (series life noted as 8,000–10,000 hours at +105°C), making it suitable for continuous high-temperature operation.
• Compact Radial Can Package — Radial lead, can-style package with dimensions L: 2.0 cm × D: 1.25 cm and 5 mm lead spacing, enabling space-efficient placement on through-hole PCBs.
• Wide Operating Temperature — Rated for −40°C to +105°C operation to accommodate a broad range of environmental conditions.
• Polarity — Polarized aluminum electrolytic design for typical DC filtering and energy-storage roles.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863), supporting regulatory requirements for restricted substances.

Typical Applications

• Power Supplies — Bulk filtering and smoothing in high-voltage switching and linear power supplies where elevated ripple-current capability and 450 V rating are needed.
• Lighting Ballasts — Energy storage and ripple handling in ballast circuits, benefitting from the part’s high ripple current and long endurance at +105°C.
• General Purpose Electronic Circuits — DC filtering and decoupling in general-purpose designs that require a compact, high-voltage electrolytic capacitor.

Unique Advantages

• High ripple-current tolerance: Meets application demands for ripple handling with 225 mA at 120 Hz and 450 mA at 100 kHz, reducing stress on upstream components.
• Extended high-temperature life: 10,000-hour rated lifetime at +105°C supports long-term reliability in elevated-temperature installations.
• Compact footprint: Small radial can (2.0 cm × 1.25 cm) and 5 mm lead spacing save board area in through-hole designs without sacrificing voltage rating.
• Wide operating range: −40°C to +105°C rating allows deployment across diverse ambient conditions.
• Regulatory compliance: RoHS conformity supports adoption in designs that must meet restricted-substance requirements.
