UTH2G161MND

The UTH2G161MND is a high-reliability, miniature aluminum electrolytic capacitor from Nichicon’s UTH series. It is a radial-lead, polarized capacitor specified at 160 µF and 400 V, designed for general-purpose power applications requiring long-term endurance and compact size.

Key value propositions include a 5000-hour endurance at 105°C, a compact φ16 × 40 mm can, and rated ripple performance specified across low and high frequencies—making it suitable for designs where high-voltage smoothing and thermal robustness are required.

Key Features

• Capacitance and Voltage — 160 µF nominal capacitance with a 400 V rated voltage, tolerance ±20% (measured at 120 Hz, 20°C).
• High Reliability / Long Life — Endurance specification: 5000 hours at 105°C under DC bias plus rated ripple current with defined limits on capacitance change, dissipation factor, and leakage current.
• Temperature Range — Operates from −40°C to +105°C to support elevated-temperature environments.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) max 0.20 at 20°C, 120 Hz; leakage current listed as 2660 µA (after 1 minute at 20°C) and 1305 µA (after 5 minutes at 20°C) for this part.
• Ripple Current Performance — Rated low-frequency ripple current 920 mA at 120 Hz (105°C) and high-frequency ripple current 1.472 A at 10 kHz, enabling effective smoothing across a range of switching frequencies.
• Compact Radial Package — φ16 × 40 mm case with 7.5 mm lead spacing (±0.5 mm), radial-lead mounting for through-hole designs; available in bulk (no terminal forming) or bag packing.

Typical Applications

• General-purpose power electronics — Bulk smoothing and energy buffering in 400 V DC circuits where compact footprint and high-voltage capability are required.
• Power supply filtering — DC link and output filtering for supplies that demand sustained ripple handling up to 1.472 A at higher switching frequencies.
• Industrial equipment — Applications requiring long endurance at elevated temperatures (up to 105°C) and stable performance over extended operating periods.

Unique Advantages

• Long endurance at elevated temperature — 5000 hours at 105°C provides predictable lifetime behavior for thermally demanding designs.
• High-voltage capability in a small can — 400 V rating in a φ16 × 40 mm package enables high-voltage designs without large board area.
• Broad ripple performance — Specified ripple current at both low (120 Hz) and high (10 kHz) frequencies supports a range of switching and line-frequency conditions.
• Defined electrical stability — Tight data on tan δ and leakage current gives engineers measurable parameters for thermal and aging design margins.
• Radial-lead form factor — Through-hole mounting and standard 7.5 mm lead spacing simplify replacement, prototyping, and assembly in typical power boards.
