UHW1H102MHD

The UHW1H102MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UHW series. It is a radial-lead, polarized can-type capacitor specified at 1000 µF and 50 V, designed for general-purpose electronic equipment requiring robust ripple handling and low impedance at higher frequencies.

Key value propositions include high ripple-current capability, a wide operating temperature range of −40°C to +105°C, and long endurance (10000 hours at 105°C), making it suitable for applications that demand stable bulk capacitance and reliable performance over time.

Key Features

• Capacitance & Voltage — 1000 µF nominal capacitance with ±20% tolerance, rated for 50 V operation.
• Low Impedance — Specified impedance of 60 mΩ, with the UHW series engineered for lower impedance at high frequencies to improve ripple attenuation.
• High Ripple Current — Handles 2.1 A at 120 Hz (low frequency) and 3.5 A at 10 kHz (high frequency), supporting applications with significant AC ripple loads.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.10 when measured at 20°C, 120 Hz for the 50 V rating.
• Reliability & Endurance — Rated for 10000 hours at 105°C under specified conditions, with defined limits for capacitance change, tan δ, and leakage after endurance testing.
• Leakage Current — Specified leakage current of 500 µA.
• Mechanical & Mounting — Radial lead / can package with dimensions φ12.5 × 30.5 mm (L), 5 mm lead spacing (±0.5 mm), and available in bulk or bag packing (no terminal forming).
• Environmental Compliance — RoHS compliant and available in mass-production quantities.

Typical Applications

• General-purpose power filtering — Bulk smoothing and decoupling in electronic power supplies that require 1000 µF capacitance at up to 50 V.
• High-ripple power circuits — Circuits with significant AC ripple benefit from the capacitor’s 2.1 A (120 Hz) and 3.5 A (10 kHz) ripple-current ratings.
• Thermally demanding environments — Systems operating across −40°C to +105°C that require long-term endurance (10000 h at 105°C).

Unique Advantages

• Designed for high ripple environments — Elevated ripple-current ratings reduce thermal stress and improve longevity in ripple-heavy circuits.
• Low high-frequency impedance — The UHW series’ lower impedance at higher frequencies supports improved AC performance and stability in decoupling roles.
• Compact radial form factor — φ12.5 × 30.5 mm can with radial leads and 5 mm lead spacing balances space efficiency and ease of through-hole mounting.
• Long endurance at elevated temperature — 10000-hour life at 105°C provides predictable aging characteristics for designs requiring long-term reliability.
• Regulatory compliance and availability — RoHS compliance and mass-production status simplify procurement and regulatory acceptance for production volumes.
