UBT2E220MHD8

The UBT2E220MHD8 is a radial-lead aluminum electrolytic capacitor designed for high-temperature, high-reliability applications. It provides 22 µF capacitance at a 250 V rating in a compact φ12.5 × 20 mm can with 5 mm lead spacing.

Engineered for demanding environments, this AEC-Q200‑qualified, RoHS‑compliant part targets automotive and other heavy‑duty electronic systems that require sustained performance up to +125°C and extended load life.

Key Features

• Electrical: 22 µF, 250 V — Rated capacitance 22 µF with ±20% tolerance at 120 Hz, 20°C, and a 250 V working voltage.
• Ripple handling — Supports 128 mA ripple current at 120 Hz (low frequency) and 230.4 mA at 100 kHz (high frequency), enabling stable operation under AC ripple stress.
• Leakage current — Specified leakage current of 320 µA after voltage application, providing predictable DC leakage behavior for system design.
• High-temperature endurance — Rated for continuous operation from −40°C to +125°C with a specified lifetime of 2000 hours at 125°C, suitable for sustained high-temperature use.
• Mechanical and packaging — Radial lead, can-style package (φ12.5 × 20 mm), 5 mm lead spacing, supplied in bulk for high-volume assembly.
• Automotive qualification & compliance — AEC‑Q200 qualified and RoHS compliant, supporting deployment in automotive electronics and regulated environments.
• Polarized aluminum electrolytic chemistry — Standard polarized design for energy storage and decoupling roles in DC power systems.

Typical Applications

• Automotive electronics — Suited for automobile electronics where heavy‑duty service and +125°C operation are required.
• High-temperature systems — Designed for equipment and modules that must maintain capacitor performance at elevated ambient temperatures.
• High-volume production assemblies — Bulk packaging and mass production status make this part appropriate for high-volume manufacturing runs.

Unique Advantages

• High-temperature capability: Operation to +125°C with a defined 2000‑hour life at that temperature enables use in hot environments without redesigning thermal management.
• Automotive-grade qualification: AEC‑Q200 qualification provides an established reliability baseline for automotive electronics and other demanding applications.
• Dual-frequency ripple performance: Specified ripple current at both 120 Hz and 100 kHz supports designers addressing both low‑frequency and high‑frequency ripple conditions.
• Compact radial can package: φ12.5 × 20 mm can with 5 mm lead spacing provides a compact footprint that fits many through‑hole assemblies.
• predictable leakage: Defined leakage current specification (320 µA) simplifies budgeting for standby currents and system leakage budgets.
• Regulatory compliance: RoHS compliance supports integration into regulated products and global supply chains.
