UTH2G201MND

The UTH2G201MND is a high-voltage, miniature aluminum electrolytic capacitor from Nichicon’s UTH series. It is a radial-lead, polarized capacitor rated at 400 V with 200 µF capacitance, designed for general-purpose high-voltage applications that require long-term stability and reliable ripple handling.

Key attributes include a compact φ18 × 40 mm can, a wide operating temperature range of −40°C to +105°C, and a guaranteed endurance of 5000 hours at 105°C, making it suitable for designs where sustained high-temperature performance and consistent electrical characteristics are required.

Key Features

• Capacitance and Voltage — 200 µF rated capacitance with a 400 V rated voltage and ±20% tolerance, providing defined energy storage for high-voltage circuits.
• High-temperature Endurance — Endurance specified as 5000 hours at 105°C under rated DC bias plus rated ripple current; capacitance remains within ±20% after test and leakage current stays at or below initial specified values.
• Ripple Current Performance — Rated ripple currents of 1.05 A at 120 Hz and 1.68 A at 10 kHz, supporting both low- and high-frequency ripple environments.
• Leakage and Dissipation — Specified leakage current of 3300 µA (after 1 minute at 20°C) and a maximum tan δ of 0.20 (measured at 120 Hz, 20°C), enabling predictable loss behavior in AC-biased conditions.
• Temperature Range — Operating temperature from −40°C to +105°C for use across a broad set of thermal environments.
• Compact Radial Package — φ18 × 40 mm can with 7.5 mm lead spacing (±0.5 mm), supplied in bulk/bag packing for standard radial-lead assembly processes.

Typical Applications

• High-voltage power circuits — Suited to general-purpose high-voltage designs that require a 400 V rated capacitor with robust ripple-handling capability and long operational life.
• Power supply filtering and energy storage — Provides bulk capacitance and smoothing in high-voltage DC circuits where 200 µF and controlled leakage are required.
• Industrial electronics — Appropriate for industrial systems operating across −40°C to +105°C that demand long-term stability and high-temperature endurance.

Unique Advantages

• 400 V rating for high-voltage designs — Enables direct use in circuits requiring 400 V components without derating for nominal voltage handling.
• Long operational life at elevated temperature — 5000 hours endurance at 105°C under rated conditions supports durability in thermally stressed installations.
• Balanced ripple performance across frequencies — Defined ripple current values at 120 Hz and 10 kHz allow reliable performance for both low- and high-frequency ripple environments.
• Predictable leakage and loss characteristics — Specified leakage current (3300 µA after 1 minute at 20°C) and tan δ ≤ 0.20 (120 Hz, 20°C) provide measurable parameters for margin and thermal planning.
• Compact radial form factor — φ18 × 40 mm can with 7.5 mm lead spacing fits space-constrained layouts while retaining high-voltage capability.
• Production-ready availability — Product listed as mass production with standard bulk/bag packing for straightforward procurement and assembly.
