ULH2G7R5MNL1GS

The ULH2G7R5MNL1GS from Nichicon is a chip-type, high-voltage aluminum electrolytic capacitor engineered for high-reliability applications. It combines a 7.5 µF capacitance with a 400 V rating in a surface-mount radial can package designed for automatic mounting using carrier tape.

Purpose-built for demanding environments, the device offers a wide operating temperature range (−40 °C to +125 °C), a rated load life of 4000 hours at +125 °C, AEC-Q200 qualification, and RoHS compliance for regulated designs.

Key Features

• Form factor & mounting: Chip-type radial can in an SMD package designed for surface-mount assembly and compatibility with carrier-tape automated mounting.
• High voltage rating: 400 V rated voltage suitable for high-voltage circuits within the ULH series rating range.
• Capacitance & tolerance: 7.5 µF with ±20% tolerance at 120 Hz, 20 °C for predictable charge storage.
• Wide temperature range & endurance: Specified for −40 °C to +125 °C with a load life of 4000 hours at +125 °C to support prolonged high-temperature operation.
• Reliability credentials: AEC-Q200 qualified and manufactured by Nichicon to support automotive-grade reliability requirements.
• Leakage and ripple characteristics: Leakage current defined by the datasheet formula (I ≤ 0.04CV + 100 µA after 1 minute at 20 °C); ripple current ratings include 50 mA at 120 Hz and 75 mA at 10 kHz for smoothing and filtering tasks.
• Compact dimensions: Size L: 1.35 × D: 1.00 cm with a recommended PCB land size of 1.03 × 1.03 cm to ease layout integration.
• Environmental compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive power electronics: Suited for in-vehicle power modules and control units where AEC-Q200 qualification and high-temperature endurance are required.
• High-voltage power supply filtering: Used for smoothing and decoupling in high-voltage power supplies and converter front-ends up to the part's 400 V rating.
• DC‑DC converter smoothing: Provides bulk capacitance and ripple attenuation for high-voltage DC‑DC stages that operate across wide temperature ranges.

Unique Advantages

• Extended high-temperature life: 4000 hours at +125 °C reduces replacement and maintenance cycles in hot operating environments.
• High-voltage capability: 400 V rating enables use in high-voltage rails without series stacking of components.
• Automated assembly ready: Surface-mount, carrier-tape compatibility streamlines high-volume PCB assembly.
• Automotive-ready reliability: AEC‑Q200 qualification supports integration into automotive systems with established reliability expectations.
• Predictable ripple and leakage behavior: Published ripple current values (50 mA at 120 Hz, 75 mA at 10 kHz) and leakage current specification allow engineers to size the part against thermal and leakage budgets.
• Compact SMD footprint: Small chip-type package and defined land pattern simplify board layout for space-constrained designs.
