UTHW6111MND

The UTHW6111MND is a radial-lead aluminum electrolytic capacitor from Nichicon's UTH series, offering 110 µF capacitance at a 420 V rating. Designed for general-purpose high-voltage circuits, it delivers long-term endurance and compact, miniature sizing for space-conscious power designs.

Key value comes from its high-voltage capability, extended 5,000 hour life at 105°C, and measurable ripple-current performance across low and high frequencies—attributes aimed at reliable bulk energy storage and smoothing in demanding power applications.

Key Features

• Electrical Characteristics — 110 µF nominal capacitance with tolerance ±20% (at 120 Hz, 20°C) and rated voltage 420 V; tangent of loss angle (tan δ) max. 0.20 at 120 Hz, 20°C.
• Ripple Current Performance — Low-frequency ripple current 740 mA (120 Hz) and high-frequency ripple current 1.184 A (10 kHz), enabling effective handling of both mains-frequency and higher-frequency ripple components.
• Leakage Current — Specified leakage current up to 1,948 µA (measurement conditions shown in datasheet), with standard leakage formulas provided for post-application limits.
• Long-Life Endurance — Rated for 5,000 hours at 105°C under DC bias plus rated ripple current; after this test capacitance remains within ±20% and tan δ remains ≤200% of initial specified value.
• Thermal and Low-Temperature Stability — Operating range −40°C to +105°C; impedance stability at low temperature is specified in the series datasheet.
• Mechanical and Packaging — Compact radial can, size φ18 × 26 mm with 7.5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing. Mass production status.

Typical Applications

• General-purpose high-voltage power circuits — Bulk capacitance and smoothing in circuits operating up to 420 V where long-term stability is required.
• Power supply filtering — Ripple attenuation and energy buffering for high-voltage power supplies within the −40°C to +105°C operating window.
• Industrial electronics — Use in industrial power modules and control equipment that require robust temperature endurance and reliable ripple handling.

Unique Advantages

• High-voltage capability: 420 V rating supports higher-voltage designs without resorting to larger components.
• Long operational life: 5,000 hours at 105°C under rated conditions provides predictable aging and lifecycle planning for products.
• Compact footprint: φ18 × 26 mm can-style package with 7.5 mm lead spacing delivers high capacitance in a small radial form factor.
• Measured ripple performance: Specified ripple currents at both 120 Hz and 10 kHz help engineers size components based on real-frequency loading conditions.
• Clear loss and leakage specifications: tan δ max. 0.20 and documented leakage current limits enable precise electrical design margins.
