UHW1K270MED

The UHW1K270MED is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UHW series, supplied in a radial lead can. It provides 27 µF capacitance at an 80 V rated voltage and is designed for general-purpose power applications that need compact size, high ripple handling and reduced impedance at higher frequencies.

Key performance highlights include low impedance at high frequency, rated ripple current support at both low and high frequencies, and an endurance rating of 8000 hours at 105°C. Status: End Of Life.

Key Features

• Capacitance & Voltage — 27 µF nominal capacitance with an 80 V rated voltage and a capacitance tolerance of -20% to +20%.
• High ripple capability — Low-frequency ripple current 200 mA (120 Hz) and high-frequency ripple current 500 mA (10 kHz), supporting power smoothing and ripple absorption in compact designs.
• Low dissipation factor — tanδ of 0.09 measured at 20°C, 120 Hz, indicating efficient AC performance for filtering and decoupling tasks.
• Miniature radial can — Compact dimensions φ6.3 × 11 mm (D × L) with radial lead mounting and 2.5 mm lead spacing (±0.5 mm), suited for space-constrained circuit layouts.
• Temperature and endurance — Rated operating temperature range of -40°C to +105°C and endurance of 8000 hours at 105°C under rated conditions.
• Leakage current — Specified leakage current of 21.6 µA, measured per the product specification after application of rated voltage.
• RoHS compliant — Manufactured in compliance with RoHS requirements.
• Packaging — Supplied in bulk (no terminal forming) or bag packing for through-hole assembly processes.

Typical Applications

• Power supply filtering — Smoothing and bulk filtering on power rails where 80 V rating and defined ripple current capability are required.
• High-frequency decoupling — Lower impedance at higher frequencies makes this part suitable for decoupling tasks in switching power stages and converters.
• Compact electronic modules — Small φ6.3 × 11 mm can and radial-lead format fit space-constrained assemblies and through-hole PCB designs.
• General-purpose electronics — Versatile choice for general-purpose power-electronic circuits that require a dependable electrolytic capacitor solution.

Unique Advantages

• Compact footprint: φ6.3 × 11 mm can and radial leads minimize PCB area while retaining useful capacitance for small power modules.
• Dual-frequency ripple support: Rated ripple currents specified at both 120 Hz and 10 kHz give clarity on performance across low- and high-frequency power conditions.
• High-temperature endurance: 8000 hours at 105°C provides a defined lifetime for designs that operate in elevated ambient temperatures.
• Predictable AC behavior: Measured tanδ (0.09 at 20°C, 120 Hz) and specified leakage current enable reliable loss and leakage budgeting in power designs.
• RoHS conformity: Meets RoHS requirements for use in regulated markets and assemblies.
