UTH2W161MND

The UTH2W161MND is a radial-lead aluminum electrolytic capacitor designed for high-voltage, compact, long-life applications. With a 450 V rated voltage and 160 µF capacitance in a φ18 × 40 mm can, it targets general-purpose power-electronics roles that require robust ripple handling and extended endurance.

Its combination of high voltage rating, wide operating temperature range (−40°C to 105°C) and a 5000-hour endurance at 105°C provides a balance of performance and reliability for engineers specifying high-voltage electrolytic components.

Key Features

• Capacitance and Tolerance — 160 µF nominal capacitance with a tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• High Voltage Rating — Rated at 450 V to support high-voltage circuits and DC bus applications.
• Long Life Endurance — Designed for 5000 hours of operation at 105°C under rated DC bias plus rated ripple current.
• Ripple Current Performance — Low-frequency ripple current of 980 mA at 120 Hz and high-frequency ripple current of 1.568 A at 10 kHz (measured conditions as specified).
• Loss Angle (tan δ) — tan δ (DF) up to 0.20 at 120 Hz, 20°C, providing predictable dissipation behavior.
• Leakage Current — Specified leakage current of 2980 µA under rated conditions (product-specific value).
• Package and Mounting — Radial lead, can-style package sized φ18 × 40 mm with 7.5 mm lead spacing (±0.5 mm), supplied in bulk/bag packing.
• Temperature Range — Operational between −40°C and +105°C to accommodate a broad range of environments.
• Polarized Device — Polarized aluminum electrolytic suitable for DC applications requiring polarized capacitance.

Typical Applications

• General-purpose power electronics — Suited for energy storage and smoothing on high-voltage DC rails where a compact, high-voltage capacitor is required.
• Industrial equipment — Use in industrial power supplies and converters that demand long endurance at elevated temperatures.
• High-voltage compact designs — Fits designs where miniature size (φ18 × 40 mm) and 450 V rating are needed together.

Unique Advantages

• High-voltage capability: 450 V rating enables design flexibility for higher DC bus voltages without multiple series capacitors.
• Compact form factor: φ18 × 40 mm radial can provides a small footprint for high-voltage capacitance in space-constrained assemblies.
• Extended thermal endurance: 5000 hours at 105°C supports long-term reliability in elevated-temperature installations.
• Broad ripple handling: Specified ripple current at both low and high frequencies (980 mA @120 Hz, 1.568 A @10 kHz) helps manage AC stress across common power-conversion frequencies.
• Predictable dissipation: tan δ specified at 0.20 (120 Hz, 20°C) for consistent loss characterization during design and thermal analysis.
• Practical packaging: Bulk/bag packing and standard 7.5 mm lead spacing facilitate through-hole assembly and handling for production runs.
