UTH2W131MND6

The UTH2W131MND6 is a high-reliability, miniature aluminum electrolytic capacitor in a radial-lead can. It delivers 130 µF capacitance at a 450 V rating with a compact φ18 × 31.5 mm case and is designed for general-purpose electronic applications that require high-voltage energy storage and long endurance.

Engineered for sustained operation at elevated temperature, the UTH2W131MND6 offers a 5,000-hour life at 105°C and proven electrical characteristics (tan δ, leakage, and ripple current) specified at standard measurement conditions.

Key Features

• Capacitance & Voltage: 130 µF rated capacitance at 450 V — suitable for high-voltage DC energy storage within the specified rating.
• High Reliability, Long Life: Life/endurance specified as 5000 hours at 105°C with performance limits for capacitance, tan δ and leakage current after endurance testing.
• Temperature Range: Rated to operate from −40°C to +105°C, supporting elevated-temperature applications.
• Loss Angle (tan δ): tan δ = 0.20 measured at 20°C, 120 Hz — specified for stability and dissipation characterization.
• Ripple Current Performance: Low-frequency ripple current 815 mA at 120 Hz and high-frequency ripple current 1.304 A at 10 kHz (specified values).
• Leakage Current: Specified leakage current of 2440 µA for this part.
• Mechanical & Mounting: Radial lead mounting, lead spacing 7.5 mm (±0.5 mm), case size φ18 × 31.5 mm, supplied in bulk (no terminal forming) or bag packing.
• Polarized Design: Polarized aluminum electrolytic construction for DC applications.

Typical Applications

• General-purpose high-voltage DC circuits: Energy storage and smoothing where a 450 V rated capacitor with 130 µF capacity is required.
• Power supply filtering: Use in filtering and bulk decoupling stages that demand long life at elevated temperatures (5000 h at 105°C).
• High-voltage electronics assemblies: Compact radial-lead form factor (φ18 × 31.5 mm) for designs with through-hole mounting and constrained board areas.

Unique Advantages

• High-voltage capability: 450 V rating allows use in higher-voltage DC circuits while staying within the component’s rated limits.
• Long endurance at temperature: 5000 hours at 105°C provides predictable aging characteristics for designs requiring extended high-temperature operation.
• Measured dissipation index: tan δ specified at 0.20 (20°C, 120 Hz) helps designers assess dissipation and thermal behavior under expected conditions.
• Defined ripple performance: Specified ripple current values at 120 Hz and 10 kHz enable designers to size capacitors for expected AC ripple stress across frequency ranges.
• Compact radial can package: φ18×31.5 mm case and 7.5 mm lead spacing provide a small footprint radial solution that is straightforward to mount in through-hole assemblies.
• Production readiness: Part is in mass production and available in bulk or bag packing options to suit manufacturing workflows.
