ULR2C390MNL1GS

The ULR2C390MNL1GS is a chip-type, surface-mount aluminum electrolytic capacitor from Nichicon's ULR series. It delivers 39 µF nominal capacitance at a 160 V rated voltage with a wide operating temperature range of −40°C to 105°C.

Designed for high-voltage, compact surface-mount applications and qualified to AEC‑Q200, this part addresses demanding environments where long endurance, controlled loss (tan δ), and measured ripple performance are required.

Key Features

• Capacitance & Tolerance — 39 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C.
• Rated Voltage — 160 V rated voltage suitable for high-voltage SMD designs.
• Low Loss Characteristic — tan δ (DF) max. 0.20 measured at 20°C, 120 Hz for controlled dissipation in AC environments.
• Ripple Performance — Specified ripple current of 70 mA at 120 Hz and 112 mA at 10 kHz to support both low- and high-frequency filtering.
• Leakage Current — Leakage current specified at 349.6 µA to help predict standby and quiescent currents in the system.
• Endurance & Reliability — 3000 hours endurance at 105°C with capacitance and leakage limits defined by the ULR series endurance test.
• Automotive-Grade — AEC‑Q200 rating for use in automotive-related applications that require component-level qualification.
• Compact SMD Package — Radial can, chip-type package with dimensions Ø10 × 13.5 mm and surface-mount land size L: 1.03 × W: 1.03 cm; shipped in embossed carrier taping for pick-and-place.

Typical Applications

• Automotive power electronics — AEC‑Q200 qualification and 160 V rating make this capacitor suitable for automotive modules requiring high-voltage bulk or decoupling capacitance across −40°C to 105°C.
• High-voltage SMD power modules — Compact chip-type can and defined ripple current ratings support compact power-supply and converter designs.
• Industrial control equipment — Endurance of 3000 hours at 105°C and controlled leakage allow predictable behavior in extended-duty industrial environments.

Unique Advantages

• Automotive-qualified construction: AEC‑Q200 rating provides documented qualification for automotive and harsh-environment use.
• High-voltage capability in an SMD form factor: 160 V rating with a Ø10 × 13.5 mm chip-type package minimizes board space while supporting higher-voltage circuits.
• Measured ripple performance across frequencies: Specified ripple currents at 120 Hz and 10 kHz let designers match capacitor selection to both low- and high-frequency filtering needs.
• Long endurance at elevated temperature: 3000 hours at 105°C enables reliable long-term operation in thermally stressed designs.
• Production-ready packaging: Embossed carrier taping supports automated assembly and high-volume manufacturing.
