UCP2W101MHD

The UCP2W101MHD is a miniature, high-voltage aluminum electrolytic capacitor in Nichicon’s UCP series, delivered in a radial-lead can for through-hole mounting. Engineered for long-life operation, this polarized capacitor provides 100 µF capacitance at a 450 V rating and is targeted for general-purpose high-voltage circuits where durable, compact energy storage and smoothing are required.

Its design emphasizes long endurance and stable performance across a wide temperature range, making it suitable for applications that require predictable behavior under continuous DC bias and elevated ambient temperatures.

Key Features

• Capacitance & Tolerance — 100 µF nominal with tolerance of −20% to +20% measured at 120 Hz, 20°C.
• High Voltage Rating — Rated for 450 V DC to support high-voltage system requirements.
• Long Endurance — Rated lifetime of 10,000 hours at 105°C with DC bias plus rated ripple current applied; capacitance change within ±20% after endurance test.
• Ripple Current Handling — Low-frequency ripple current 730 mA at 120 Hz and high-frequency ripple current 1.095 A at 10 kHz, enabling effective ripple absorption across a range of frequencies.
• Loss Characteristics — tan δ (DF) maximum 0.24 measured at 120 Hz, 20°C for controlled dissipation factor.
• Leakage Current — Specified leakage current of 1900 µA (measured after 1 minute at 20°C under rated voltage conditions).
• Temperature Range — Operates from −40°C to +105°C for broad environmental compatibility.
• Compact Radial Package — Case size φ16 × 35.5 mm (L: 3.55 × D: 1.6 cm) with 7.5 mm lead spacing (±0.5 mm); supplied as radial lead, polarized can in bulk or bag packing.

Typical Applications

• General-purpose power filtering — Provides 100 µF at 450 V for smoothing and bulk energy storage in high-voltage circuits that require long life at elevated temperatures.
• High-voltage DC circuits — Suited for DC link or high-voltage smoothing tasks where a compact, high-voltage polarized capacitor is needed.
• Industrial electronics — Use in assemblies that demand stable capacitance and controlled dissipation over long endurance periods up to 10,000 hours at 105°C.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage designs without up‑grading to larger packages.
• Designed for long service life: 10,000 hours endurance at 105°C provides predictable long-term performance under continuous load.
• Wide operating temperature range: −40°C to +105°C supports deployment across varied thermal environments.
• Balanced ripple performance: Specified ripple currents at both low (120 Hz) and high (10 kHz) frequencies support multi-frequency ripple absorption requirements.
• Compact radial form factor: φ16 × 35.5 mm can with 7.5 mm lead spacing offers a space-efficient through-hole solution for board-level assemblies.
