UBT1J331MHD8

The UBT1J331MHD8 is a radial-lead aluminum electrolytic capacitor from Nichicon's UBT series, rated at 330 µF and 63 V. Built for high-temperature, heavy-duty service, it is designed for demanding in-vehicle and industrial electronics where long life and stable performance at elevated temperatures are required.

Key design attributes include a +125°C operating range, AEC-Q200 qualification, low impedance and defined ripple-current capability—making this part suitable where sustained high-temperature endurance and reliable bulk energy storage are priorities.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 63 V rated working voltage and ±20% tolerance at 120 Hz, 20°C.
• High‑Temperature Endurance — Specified for operation from −40°C to +125°C with a rated lifetime of 5000 hours at 125°C.
• Reliability & Qualification — AEC-Q200 qualified and designed for sustained automotive-duty service.
• Low Impedance & Loss — Typical impedance 120 mΩ and a maximum tan δ of 0.10 at 120 Hz, 20°C (63 V rating), supporting effective ripple handling and energy storage.
• Ripple Current Capability — Rated ripple current of 864.3 mA at 120 Hz and 1.29 A at 100 kHz for reliable AC stress performance.
• Packaging & Mounting — Radial lead, can-style package (φ12.5 × 25L) with 5 mm lead spacing; supplied in bulk/bag for mass-production assembly.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Automotive electronics — Suited for in-vehicle electronic modules that require high-temperature endurance and AEC‑Q200 qualification.
• Power supply filtering — Bulk energy storage and smoothing where sustained ripple handling and low impedance are needed at elevated temperatures.
• Heavy-duty electronic assemblies — Components subject to continuous high-temperature operation and long service life requirements.
