UTH2W141MND

The UTH2W141MND from Nichicon is a radial-lead aluminum electrolytic capacitor in the UTH series designed for high-voltage, miniature-sized, long-life applications. It delivers 140 µF capacitance at a 450 V rating and is intended for general-purpose use where a compact, high-voltage electrolytic solution is required.

Key value propositions include a 450 V rated voltage, long endurance (5,000 hours at 105 °C), and compact radial-can packaging (φ18 × 36 mm) with 7.5 mm lead spacing for through-hole designs and manual or wave assembly processes.

Key Features

• High Voltage Rating (450 V)  Rated for 450 V operation, suitable for designs that require a high-voltage electrolytic capacitor.
• Capacitance 140 µF ±20%  Nominal capacitance of 140 µF with ±20% tolerance specified at 120 Hz, 20 °C.
• Low Loss (tan δ = 0.20)  Specified maximum tangent of loss angle (tan δ) of 0.20 at 120 Hz, 20 °C for controlled dissipation.
• High ripple current capability  Rated ripple currents of 900 mA at 120 Hz and 1.44 A at 10 kHz provide defined AC performance for low- and high-frequency conditions.
• Long Endurance – 5,000 h at 105 °C  Endurance specification: capacitance change within ±20%, tan δ ≤ 200% of initial spec, and leakage current ≤ initial spec after 5,000 hours at 105 °C with rated bias and ripple.
• Wide Operating Temperature Range  Specified from −40 °C to +105 °C to cover elevated temperature operating environments.
• Compact Radial Can Package  Physical size φ18 × 36 mm with radial leads and 7.5 mm lead spacing (±0.5 mm) for through-hole mounting and easy placement in compact assemblies.
• Packaging and Availability  Supplied in bulk/no terminal forming or bag packing; part is in mass production.

Typical Applications

• General-purpose high-voltage circuits  Use where a 450 V rated, 140 µF radial-lead capacitor is required for general-purpose designs.
• High-temperature endurance applications  Suited to designs requiring long life at elevated temperature, backed by a 5,000-hour rating at 105 °C.
• Compact radial-lead assemblies  Ideal when a miniature can-style capacitor (φ18 × 36 mm) with 7.5 mm lead spacing is needed for through-hole layouts.

Unique Advantages

• High-voltage capability: 450 V rating allows deployment in circuits that demand elevated DC working voltages.
• Defined long-term reliability: 5,000-hour endurance at 105 °C with specified limits on capacitance change, tan δ, and leakage current provides predictable aging behavior.
• Clear AC performance specs: Published ripple current ratings at 120 Hz and 10 kHz (900 mA and 1.44 A respectively) simplify thermal and ripple budgeting.
• Compact footprint: φ18 × 36 mm can with radial leads and 7.5 mm spacing offers a small physical profile for high-voltage, through-hole designs.
• Consistent dissipation characteristics: Maximum tan δ of 0.20 at 120 Hz, 20 °C supports predictable ESR-related behavior in design calculations.
