UPW1H220MDD

The UPW1H220MDD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UPW series designed for low-impedance, high-reliability power applications. It provides 220 µF capacitance at a 50 V rating with a compact φ5 × 11 mm can and 2 mm lead spacing for dense board layouts.

Engineered for sustained operation across a wide temperature range (−55 °C to 105 °C) and rated for 2000 hours at 105 °C, this part is suited to demanding switching power supplies and applications requiring AEC-Q200-level reliability for automotive designs. Status: End Of Life.

Key Features

• Capacitance and Voltage: 220 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance, suitable for bulk and decoupling roles in power circuits.
• Low dissipation (tan δ): Dissipation factor specified at 0.10 (measured at 20 °C, 120 Hz), supporting lower losses in AC ripple conditions.
• Ripple current capability: Specified low-frequency ripple current of 51 mA (120 Hz) and high-frequency ripple current of 170 mA (10 kHz), enabling effective smoothing in switching supplies.
• Low leakage current: Leakage current listed at 33 µA, minimizing standby and quiescent losses.
• High-temperature endurance: Rated life of 2000 hours at 105 °C, providing predictable aging characteristics in elevated-temperature environments.
• Compact radial package: φ5 × 11 mm can (L: 1.1 × D: 0.5 cm) with 2 mm lead spacing and radial lead mounting for through-hole assembly and secure mechanical retention.
• Automotive-grade reliability: AEC-Q200 listed in the product specifications, indicating suitability for automotive electronics applications where that qualification is required.
• Polarized design: Polar aluminum electrolytic construction for standard DC power filtering and energy storage functions.
• Packaging options: Supplied in bulk (no terminal forming) or bag-packed formats for flexible procurement and assembly handling.

Typical Applications

• Switching Power Supplies: Bulk filtering and output smoothing in compact DC–DC converters and switch-mode power supplies where low impedance and ripple handling are required.
• Automotive Electronics: Power supply filtering and decoupling in automotive modules and control units, supported by the part’s AEC-Q200 listing and high-temperature endurance.
• Compact Power Conversion Modules: Space-constrained power stages and modules that benefit from the capacitor’s miniature φ5 × 11 mm package and radial lead mounting.

Unique Advantages

• Space-efficient power smoothing: φ5 × 11 mm can size and 2 mm lead spacing help reduce board area for power filtering components.
• Measured low-loss performance: tan δ = 0.10 at 20 °C, 120 Hz supports efficient operation with controlled dielectric losses in AC environments.
• Targeted ripple handling: Specified ripple currents at both low and high frequencies address real-world switching supply ripple spectra.
• Controlled leakage: 33 µA leakage current reduces parasitic drain on supply rails and aids in power-sensitive designs.
• Designed for elevated temperatures: 2000 hours at 105 °C rating provides predictable life characteristics in hot operating conditions.
• Automotive-ready qualification: Inclusion of AEC-Q200 in specifications supports selection for automotive electronics where that qualification is required.
