UBT2E330MHD

The UBT2E330MHD is a 33 µF, 250 V aluminum electrolytic capacitor in a radial-can package designed for demanding high-temperature environments. It delivers polarized capacitance with wide operating temperature range and defined ripple-current performance for electronics that require sustained operation at elevated temperatures.

Built to meet automotive-grade expectations, the part combines a 250 V rating, AEC-Q200 qualification, and RoHS compliance to serve applications that require reliable performance up to +125°C.

Key Features

• Capacitance & Tolerance — 33 µF nominal with tolerance of −20% to +20% at 120 Hz, 20°C.
• Rated Voltage — 250 V DC rating suitable for higher-voltage circuitry within the specified limits.
• High-temperature Endurance — Rated for 2000 hours at +125°C under specified test conditions, supporting sustained high-temperature operation.
• Ripple Current Performance — Low-frequency ripple current 171 mA (120 Hz) and high-frequency ripple current 307.8 mA (100 kHz), enabling handling of both LF and HF ripple components.
• Leakage & Loss — Leakage current specified at 430 µA and tan δ (loss tangent) of 0.20 measured at 120 Hz, 20°C.
• Mechanical Package — Radial lead, can-style package with dimensions φ12.5 × 25 mm (D × L) and 5 mm lead spacing (±0.5 mm), for through-hole mounting.
• Polarized Construction — Polar capacitor architecture for DC circuit applications.
• Compliance — RoHS compliant and AEC-Q200 qualified.
• Packaging Options — Available in bulk (no terminal forming) and bag packing.

Typical Applications

• Automotive electronics — Suited for automobile electronics where sustained operation up to +125°C and AEC-Q200 qualification are required.
• High-temperature power systems — Applicable to power circuits operating at elevated ambient temperatures that require a 250 V polarized capacitor.
• Through-hole assemblies — Radial lead can package with 5 mm lead spacing for traditional PCB through-hole mounting in demanding environments.

Unique Advantages

• High-temperature capability: Rated for operation from −40°C to +125°C with a defined 2000-hour endurance at +125°C, supporting designs that face prolonged thermal stress.
• AEC-Q200 qualification: Provides an automotive-focused quality baseline for use in vehicle electronics and similarly demanding applications.
• Dual-frequency ripple handling: Specified ripple currents at 120 Hz and 100 kHz (171 mA / 307.8 mA) allow designers to account for both low- and high-frequency ripple in system budgets.
• Compact radial can: φ12.5 × 25 mm package with standard 5 mm lead spacing eases mechanical integration for through-hole assemblies.
• Regulated electrical characteristics: Clear specifications for leakage current (430 µA) and tan δ (0.20 at 120 Hz, 20°C) support predictable performance and design validation.
• Standards and environmental compliance: RoHS compliance reduces regulatory overhead for environmental directives.
