UCP2W151MHD

The UCP2W151MHD is a radial‑lead aluminum electrolytic capacitor in Nichicon's UCP series, designed for high‑voltage, miniature‑sized, long‑life applications. It delivers 150 µF at a 450 V rating with a compact φ18 × 40 mm can and 7.5 mm lead spacing.

This part is targeted at general‑purpose high‑voltage designs that require extended endurance (10,000 hours at 105°C), stable loss characteristics (tanδ 0.24 at 120 Hz, 20°C) and practical ripple handling across low and high frequencies.

Key Features

• Core electricals — 150 µF capacitance with a tolerance of -20% to +20% and a rated voltage of 450 V.
• Loss angle (tanδ) — Maximum tanδ 0.24 measured at 20°C and 120 Hz, enabling predictable dissipation characteristics.
• Ripple current capability — Rated low‑frequency ripple current 970 mA (120 Hz) and high‑frequency ripple current 1.455 A (10 kHz), supporting both mains‑frequency and higher‑frequency ripple environments.
• Leakage current — Specified leakage current 2800 µA (after 1 minute at 20°C under rated voltage), enabling straightforward power‑budgeting.
• Long endurance — Designed for 10,000 hours at 105°C under DC bias plus rated ripple current, with defined limits for capacitance change, tanδ and leakage after endurance testing.
• Robust operating range & mounting — Polarized radial‑lead mounting for through‑hole assemblies; operating temperature range -40°C to +105°C; package size φ18 × 40 mm with 7.5 mm lead spacing and 0.5 mm spacing tolerance.
• Packaging & availability — Supplied in bulk or bag packing (no terminal forming) and listed as mass production status.

Typical Applications

• General‑purpose high‑voltage circuits — Use where a 450 V rated capacitor is required for energy storage and smoothing in high‑voltage designs.
• Power supply ripple suppression — Suited to filtering and ripple handling at 120 Hz and at higher frequencies given the specified ripple current coefficients.
• Thermally demanding environments — Appropriate for designs requiring extended operation at elevated temperatures up to 105°C thanks to the 10,000‑hour endurance rating.

Unique Advantages

• High voltage capability: 450 V rating supports designs that require higher DC voltage handling without series stacks.
• Compact, serviceable form factor: φ18 × 40 mm radial can with 7.5 mm lead spacing provides a balance of capacitance and PCB footprint for through‑hole assemblies.
• Frequency‑spanning ripple performance: Specified ripple current at both 120 Hz and 10 kHz enables predictable thermal and lifetime planning across common ripple sources.
• Long life at elevated temperature: 10,000 hours at 105°C under rated conditions delivers a quantifiable endurance metric for lifetime planning.
• Measurable loss and leakage specs: Defined tanδ (0.24) and leakage current (2800 µA) at standardized conditions help with thermal and leakage budgets during design.
• Production readiness: Available in bulk or bag packing and listed as mass production for predictable procurement and supply.
