UBW1K220MPD

The UBW1K220MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UBW series designed for high-temperature, long-life applications. It provides 22 µF nominal capacitance at an 80 V rating with polarization and is optimized for applications requiring stable performance to +135 °C.

Engineered for use in environments where thermal endurance, controlled leakage and predictable ripple handling matter, this part is suitable for automotive and industrial power electronics that demand compact, robust passives.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance with an 80 V rated voltage and a tolerance of −20% to +20% for predictable energy storage and design margins.
• High-Temperature Endurance — Rated operating range −55 °C to +135 °C with an endurance specification of 1000 hours at 135 °C.
• Ripple & Loss Characteristics — Low-frequency ripple current 100.5 mA (120 Hz) and high-frequency ripple current 150 mA (10 kHz), with tan δ = 0.08 measured at 20 °C, 120 Hz for controlled dissipation.
• Leakage & Impedance — Specified leakage current 52.8 µA and impedance of 1.5 Ω, aiding in stable bias performance and predictable power-loss behavior.
• Package & Mounting — Compact radial-can package (φ8 × 11.5 mm length) with 3.5 mm lead spacing (±0.5 mm) for through-hole PCB mounting in confined assemblies.
• Automotive-Grade Qualification — AEC-Q200 rating suitable for designs that require recognized automotive component qualification.
• Availability & Packaging — Mass production status with Bulk (no terminal forming) and Bag packing options to support production procurement.

Typical Applications

• Automotive electronics — Suited for power filtering and decoupling in automotive systems where the AEC-Q200 rating and +135 °C endurance are required.
• Industrial power supplies — Provides bulk smoothing and ripple filtering in high-voltage 80 V rails operating in elevated-temperature environments.
• DC–DC converters and power modules — Compact radial form factor and defined ripple current ratings support energy storage and transient suppression in power conversion stages.
• Embedded and control electronics — Reliable polarized capacitance with low leakage for long-life operation in control units and electronic modules exposed to wide temperature swings.

Unique Advantages

• High-temperature capability: Rated −55 °C to +135 °C with 1000 hours endurance at 135 °C, enabling deployment in thermally challenging applications.
• Automotive qualification: AEC-Q200 rating provides documented suitability for automotive design requirements and verification workflows.
• Compact footprint: Small φ8 × 11.5 mm radial can with 3.5 mm lead spacing allows placement in space-constrained through-hole designs.
• predictable ripple handling: Specified ripple currents at 120 Hz and 10 kHz (100.5 mA and 150 mA respectively) let designers account for AC stress across the expected frequency range.
• Measured dissipation and leakage: tan δ = 0.08 (20 °C, 120 Hz) and 52.8 µA leakage current provide quantifiable electrical behavior for thermal and power-loss calculations.
• Production-ready supply: Mass production status and standard bulk/bag packing simplify BOM sourcing and volume procurement.
