UTH2G750MND

The UTH2G750MND is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UTH series. It is a radial-lead, polarized capacitor rated 75 µF at 400 V, designed for general-purpose use where high voltage, compact size and long operational life are required.

Key attributes include a wide operating temperature range of −40℃ to 105℃, endurance of 5000 hours at 105℃, and compact dimensions (φ18 × 20 mm) with 7.5 mm lead spacing, making it suitable for space-constrained power circuits that require robust high-voltage smoothing and ripple handling.

Key Features

• Voltage & Capacitance — Rated at 400 V with 75 µF capacitance and tolerance ±20%, providing defined energy storage for high-voltage circuit requirements.
• Long Life Endurance — Rated for 5000 hours at 105℃ under DC bias plus rated ripple current, meeting endurance criteria for extended high-temperature operation.
• Temperature Range — Operates from −40℃ to 105℃ to support a wide range of environmental conditions.
• Low- and High-Frequency Ripple Handling — Specified ripple current performance of 550 mA (120 Hz) and 880 mA (10 kHz), enabling effective smoothing across frequency ranges.
• Leakage and Loss Characteristics — Leakage current approximately 1300 µA (at 20℃ after 1 minute) with tan δ (loss tangent) max 0.20 at 120 Hz and 20℃ for stable electrical behavior.
• Compact Radial Package — φ18 × 20 mm can with 7.5 mm lead spacing (±0.5 mm) in a radial-lead form factor; available in bulk (no terminal forming) or bag packing.
• Mass Production Availability — Product is in mass production, suitable for volume designs and procurement planning.

Typical Applications

• General-purpose power supplies — Energy storage and smoothing in high-voltage DC rails where 400 V rating and 75 µF capacitance are required.
• Industrial power conversion — DC link and ripple suppression in compact, high-voltage converter modules operating up to 105℃.
• Instrumentation and test equipment — Compact high-voltage filtering in bench or rack systems that demand predictable leakage and loss characteristics.

Unique Advantages

• High-voltage capability: 400 V rating enables use in high-voltage circuits without upsizing to larger packages.
• Compact footprint: φ18 × 20 mm can with 7.5 mm lead spacing conserves PCB space for dense designs.
• Long operational life: 5000 hours at 105℃ provides predictable longevity for elevated-temperature applications.
• Frequency-flexible ripple performance: Specified ripple currents at 120 Hz (550 mA) and 10 kHz (880 mA) support both low- and high-frequency smoothing needs.
• Measured electrical stability: Low tan δ (≤0.20 at 120 Hz, 20℃) and defined leakage current figures support consistent circuit behavior and easier validation.
• Production-ready supply: Mass production status and standard radial-lead packaging simplify sourcing and assembly flow.
