UHW1A182MPD

The UHW1A182MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for general-purpose electronic applications. It delivers high capacitance (1800 µF) at a 10 V rating while maintaining low impedance and elevated ripple-current capability for demanding power and filtering tasks.

Built for sustained operation across a wide temperature range, this radial-lead component is optimized for designs that require compact size, long endurance, and robust ripple handling in general-purpose equipment.

Key Features

• Capacitance & Voltage: 1800 µF rated at 10 V, with a capacitance tolerance of -20%/+20% for predictable bulk energy storage.
• High ripple-current capability: Low-frequency ripple current of 1.5 A (120 Hz) and high-frequency ripple current of 2.5 A (10 kHz), enabling effective AC ripple handling.
• Low impedance: Specified impedance of 60 mΩ supports lower voltage drop under dynamic load conditions.
• Loss characteristic (tan δ): tanδ 0.18 measured at 20°C, 120 Hz, supporting stable dissipation characteristics for this part.
• Reliability and endurance: Rated for 10,000 hours at 105°C, reflecting suitability for long-life applications under elevated temperature stress.
• Temperature range: Operational from -40°C to +105°C to accommodate a broad range of environmental conditions.
• Package and mounting: Radial lead can, size φ10 × 20 L, lead spacing 5 mm (±0.5 mm), supplied bulk or bag-packed (no terminal forming) for flexible assembly options.
• Leakage current: Specified leakage current of 180 µA under rated conditions to support predictable standby characteristics.
• RoHS compliant: Conforms to RoHS directive requirements for restricted substances.

Typical Applications

• General-purpose electronic equipment: Bulk energy storage and smoothing in a variety of consumer and industrial boards where a reliable, compact electrolytic capacitor is required.
• Power supply modules: Filtering and ripple suppression in power-supply sections that demand elevated ripple-current capability at both low and high frequencies.
• Industrial control electronics: Energy buffering and decoupling in control modules that operate across a wide temperature range and require long endurance.
• Compact assemblies: Space-constrained designs benefitting from the φ10 × 20 L can and radial-lead mounting with 5 mm lead spacing.

Unique Advantages

• High ripple-current handling: Rated for 1.5 A at 120 Hz and 2.5 A at 10 kHz, enabling stable performance under significant AC stress.
• Compact, high-capacitance footprint: 1800 µF in a φ10 × 20 L radial can reduces board area compared with larger-diameter options.
• Long endurance at elevated temperature: 10,000-hour rating at 105°C provides predictable service life in thermally demanding environments.
• Low impedance: 60 mΩ impedance supports improved dynamic response and reduced power dissipation in filtering applications.
• Robust environmental range: Operating from -40°C to +105°C suits a wide variety of deployment conditions.
• Supply flexibility: Available in bulk (no terminal forming) or bag packing to accommodate different assembly workflows.
