UPZ2W180MPD

The UPZ2W180MPD is a radial‑lead aluminum electrolytic capacitor in Nichicon’s UPZ series, engineered for compact, high‑voltage, general‑purpose applications. It delivers 18 µF capacitance at a 450 V rated voltage in a miniature φ10 × 30.5 mm can with radial leads.

Designed for assemblies that require elevated temperature endurance and defined ripple handling, this part combines a small footprint with measurable electrical characteristics (tan δ, leakage current and ripple current) to help engineers specify predictable performance in high‑voltage circuits.

Key Features

• Electrical Rating: 18 µF nominal capacitance with a tolerance of −20% to +20% at 120 Hz, 20 °C, and a 450 V rated voltage.
• Dissipation Factor (tan δ): tan δ = 0.20 (measured at 20 °C, 120 Hz for 450 V rating), providing a quantified measure of AC loss for design verification.
• Leakage Current: Specified leakage current 424 µA (measured condition per product data), enabling predictable bias‑current budgeting in high‑voltage designs.
• Ripple Current Capability: Low‑frequency ripple current 180 mA at 120 Hz and high‑frequency ripple current 270 mA at 10 kHz, with frequency coefficients provided for scaling across frequencies.
• Compact Radial Can: Case size φ10 × 30.5 mm (L 30.5 mm, D 10 mm) with radial lead spacing 5.0 mm (±0.5 mm) and lead diameter φd = 0.6 mm for the φ10 case.
• Temperature and Endurance: Rated for −40 °C to +105 °C operation with life/endurance specified as 2000 hours at 105 °C under rated voltage plus rated ripple current.
• Polarized, Through‑Hole Mounting: Radial lead configuration and polarized construction for straightforward through‑hole assembly; packaging available in bulk (no terminal forming) or bag packing.

Typical Applications

• High‑voltage power supply filtering: Use on 450 V rails where compact, defined capacitance and ripple handling are required for smoothing and decoupling.
• DC link and energy buffering: Small‑form high‑voltage circuits that need compact capacitance with specified leakage and dissipation characteristics.
• Industrial and general‑purpose electronics: Circuits operating across −40 °C to +105 °C that require predictable long‑term endurance (2000 h at 105 °C) in a radial lead package.

Unique Advantages

• High‑voltage capability in a miniature package: 450 V rating in a φ10 × 30.5 mm can minimizes board area for high‑voltage designs.
• Quantified AC and leakage parameters: Specified tan δ (0.20) and measured leakage current (424 µA) allow engineers to budget losses and bias currents precisely.
• Frequency‑aware ripple performance: Published ripple current values at 120 Hz and 10 kHz with frequency coefficients support ripple scaling for both low and high frequency applications.
• Robust thermal endurance: Rated for −40 °C to +105 °C with a 2000‑hour life at 105 °C, supporting long‑life operation in elevated temperature environments.
• Through‑hole convenience and packaging flexibility: Radial lead form (5.0 mm spacing, 0.6 mm lead diameter for φ10) and bulk or bag packing simplify assembly and handling for production or prototyping.
• Mass production availability: Product status listed as mass production for predictable sourcing and supply continuity.
