UBT2G330MHD

The UBT2G330MHD is a radial-leaded aluminum electrolytic capacitor with 33 µF capacitance and a 400 V rated voltage. It is designed for high-temperature, high-voltage applications where durable, polarized capacitance is required.

Built to operate from −25 °C to 125 °C and qualified to AEC‑Q200, this component targets automotive and other heavy‑duty electronic systems that require long endurance and stable performance under elevated temperature and ripple conditions.

Key Features

• Capacitance & Voltage: 33 µF nominal capacitance with a 400 V rated voltage and capacitance tolerance of −20% to +20%.
• High‑temperature endurance: Rated for operation up to 125 °C with an endurance specification of 2000 hours at 125 °C.
• AEC‑Q200 qualified: Part of the UBT series meeting AEC‑Q200 requirements for use in demanding automotive environments.
• Ripple performance: Low‑frequency ripple current 189 mA at 120 Hz and high‑frequency ripple current 340.2 mA at 100 kHz, enabling use in power filtering and smoothing roles under AC ripple stress.
• Electrical loss & leakage: Dissipation factor (tan δ) 0.24 (measured at 20 °C, 120 Hz) and leakage current 628 µA, providing predictable loss and leakage characteristics for circuit design.
• Radial package & dimensions: Radial can package, φ16 × 25 mm body size with 7.5 mm lead spacing (±0.5 mm) for through‑hole mounting and straightforward board placement.
• Compliance & packing: RoHS compliant; available in bulk (no terminal forming) or bag packing.

Typical Applications

• Automotive electronics: Suited for automobile electronics where heavy‑duty service and high‑temperature operation are indispensable.
• High‑voltage power filtering: 400 V rating and defined ripple current figures make it appropriate for smoothing and decoupling in high‑voltage power supplies.
• High‑temperature power circuits: Engineered for sustained operation at elevated temperatures up to 125 °C with specified endurance.

Unique Advantages

• High‑voltage capability: 400 V rating supports designs that require elevated DC bus voltages without stacking or series arrangements.
• Designed for elevated temperatures: Specified operation to 125 °C and a 2000‑hour endurance at that temperature provide predictable lifetime characteristics in hot environments.
• Automotive‑grade qualification: AEC‑Q200 qualification indicates suitability for demanding automotive electronic systems.
• Clear electrical characterization: Published tan δ, leakage current and ripple current values allow accurate thermal and reliability margins in power designs.
• Through‑hole robustness: Radial lead configuration and standardized lead spacing simplify mechanical mounting and serviceability.
