UTH2G181MND

The UTH2G181MND is a high-voltage, miniature aluminum electrolytic capacitor from Nichicon’s UTH series. It is a radial-lead, high-reliability type rated at 180 µF and 400 V, designed for general-purpose power circuit use where elevated temperature endurance and compact size are required.

Key design attributes include a wide operating temperature range of -40°C to 105°C, long endurance (5000 hours at 105°C), and compact dimensions (φ18 × 36 mm) with 7.5 mm lead spacing for through-hole mounting.

Key Features

• Rated Capacitance & Voltage — 180 µF nominal capacitance with a rated voltage of 400 V and capacitance tolerance of -20% to +20% (120 Hz, 20°C).
• High-temperature Endurance — Life rating of 5000 hours at 105°C with specified limits: capacitance change within ±20%, tan δ up to 200% of initial specified value, and leakage current ≤ initial specified value after the endurance test.
• Loss Angle (tan δ) — tan δ (DF) max 0.20 measured at 20°C, 120 Hz for the 400 V rating.
• Leakage Current — 2,980 µA (after 1 minute at 20°C, rated voltage) and 1,465 µA (after 5 minutes at 20°C, rated voltage) as published for this part.
• Ripple Current Capability — Low-frequency ripple current: 950 mA at 120 Hz (105°C). High-frequency ripple current: 1.52 A at 10 kHz (105°C).
• Miniature Radial Package — Compact can-style package: φ18 × 36 mm (lead spacing 7.5 mm, tolerance ±0.5 mm), radial lead mounting for PCB through-hole implementations. Packaging available in bulk (no terminal forming) and bag packing; part is in mass production.

Typical Applications

• General-purpose power circuits — Suitable where a 400 V, 180 µF electrolytic capacitor is required for general-purpose power designs.
• High-temperature environments — Applicable in designs that require operation across -40°C to 105°C and long life at elevated temperature (5000 hours at 105°C).
• Through-hole PCB assemblies — Radial lead form and 7.5 mm lead spacing support conventional through-hole mounting and assembly workflows.

Unique Advantages

• High-voltage capability: 400 V rating enables use in higher-voltage power circuits without requiring larger footprint alternatives.
• Long life at elevated temperature: 5000-hour endurance at 105°C provides predictable aging and reliability for extended service life.
• Compact footprint: φ18 × 36 mm dimensions deliver high capacitance in a miniature radial-can package for space-constrained designs.
• Robust ripple handling: Rated ripple currents of 950 mA (120 Hz) and 1.52 A (10 kHz) at 105°C accommodate a range of AC ripple conditions.
• Measured electrical stability: Low tan δ (0.20 at 120 Hz, 20°C) and defined leakage current figures support predictable performance and easier thermal/ripple budgeting.
• Production-ready packaging: Available in bulk or bag packing and listed as mass production, simplifying procurement and supply planning.
