UHW1H182MHD

The UHW1H182MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can package. It delivers 1800 µF capacitance at a 50 V rating with a compact φ16 × 30.5 mm case and 7.5 mm lead spacing.

Designed for general-purpose applications that require high ripple handling and long endurance, this radial-lead unit combines low impedance, high-frequency ripple capability, and a wide operating temperature range of −40 °C to 105 °C.

Key Features

• Electrical Performance: 1.8 mF capacitance at 50 V with an impedance of 57 mΩ, providing substantial bulk capacitance in a small package.
• High Ripple Current: Low-frequency ripple current of 2.058 A (120 Hz) and high-frequency ripple current of 3.43 A (10 kHz), suitable for applications with significant AC ripple content.
• Dissipation & Loss: Tangent of loss angle (tan δ) of 0.1 measured at 20 °C, 120 Hz (note: tan δ increases with capacitance as noted in the series datasheet).
• Leakage Current: Specified leakage current of 900 µA.
• Reliability & Lifetime: Endurance rated for 10,000 hours at 105 °C under rated voltage and ripple stress.
• Temperature Range: Broad operating range from −40 °C to 105 °C for stable performance across typical environmental conditions.
• Package & Mounting: Radial lead can (φ16 × 30.5 mm) with 7.5 mm lead spacing; available in bulk (no terminal forming) or bag packing.
• RoHS Compliant: Meets RoHS requirements as indicated in the product data.

Typical Applications

• General Purpose Electronics — Suited to circuits requiring compact bulk capacitance and reliable long-term operation under continuous bias.
• High-Ripple Power Sections — Used where elevated ripple currents and low impedance at higher frequencies are required, leveraging the UHW series’ high ripple capability.
• Temperature-Variable Environments — Applicable in designs that demand stable performance across −40 °C to 105 °C and extended endurance at elevated temperature.

Unique Advantages

• Compact, high-capacitance solution: 1800 µF in a φ16 × 30.5 mm can minimizes board area while providing substantial energy storage.
• High ripple handling: Specified ripple currents of 2.058 A (120 Hz) and 3.43 A (10 kHz) reduce stress on upstream regulators and smoothing networks.
• Low core impedance: 57 mΩ series impedance supports improved transient response and reduced voltage ripple.
• Long endurance at high temperature: 10,000-hour rated life at 105 °C supports reliable operation in demanding thermal environments.
• Radial-lead flexibility: Standard lead spacing (7.5 mm) and bulk/bag packing options simplify through-hole assembly and inventory choices.
• Regulatory compliance: RoHS compliance supports use in designs targeting restricted-substance conformity.
