UHW1J122MHD6

The UHW1J122MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from the Nichicon UHW series, supplied in a radial-lead can. It delivers 1200 µF of capacitance at a 63 V rating with design attributes focused on low impedance and high ripple-current capability for general-purpose electronic applications.

Designed for compact circuits where sustained ripple handling and long-term endurance are required, this part is offered in bulk/bag packing and is in mass production.

Key Features

• Capacitance and tolerance — 1200 µF with a capacitance tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Rated voltage — 63 V working voltage suitable for mid-voltage power rails.
• Low impedance — Impedance specified at 110 mΩ, supporting improved AC performance in filtering and decoupling roles.
• High ripple-current capability — Low-frequency ripple current of 1.758 A (120 Hz) and high-frequency ripple current of 2.93 A (10 kHz) for demanding AC conditions.
• Long endurance — Life specification of 12,000 hours at 105°C under rated conditions.
• Temperature range — Operating range from -40°C to 105°C for wide environmental tolerance.
• Leakage and dissipation — Leakage current 756 µA and tan δ (DF) of 0.09 measured at 20°C, 120 Hz.
• Form factor — Radial lead can, dimensions φ18 × 25L mm with 7.5 mm lead spacing (±0.5 mm), available in bulk/no terminal forming or bag packing.
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose electronics — Provides bulk energy storage and smoothing in general-purpose circuits where reliable ripple handling and compact size are needed.
• Power supply filtering — Low impedance (110 mΩ) combined with 1.758 A (120 Hz) / 2.93 A (10 kHz) ripple ratings support AC ripple suppression on mid-voltage rails.
• Industrial equipment — Extended operating temperature (-40°C to 105°C) and 12,000-hour endurance at 105°C make it suitable for sustained operation in industrial environments.

Unique Advantages

• High ripple-current capability: Specified ripple currents at both low and high frequencies enable reliable handling of AC stress in compact layouts.
• Low impedance performance: 110 mΩ impedance helps reduce voltage ripple and improve transient response in power circuits.
• Compact radial-lead package: φ18 × 25L mm can size with 7.5 mm lead spacing provides a space-efficient option for through-hole assemblies.
• Long high-temperature life: 12,000 hours at 105°C supports predictable long-term performance in elevated-temperature applications.
• Wide operating temperature: -40°C to 105°C range accommodates a broad set of environmental conditions.
• RoHS compliance: Meets RoHS directive requirements for restricted substances.
