UBT2E220MHD

The UBT2E220MHD is a radial-lead aluminum electrolytic capacitor designed for high-temperature, high-voltage applications. It delivers 22 µF capacitance at a 250 V rating with a polar radial-can package optimized for robust through-hole mounting and bulk handling.

Engineered for demanding electronics, the part combines a wide operating temperature range (−40°C to +125°C), AEC-Q200 qualification, and a specified load-life of 2000 hours at 125°C to support designs that require sustained performance under elevated temperature and stress.

Key Features

• Capacitance & Voltage: 22 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance, suitable for higher-voltage smoothing and energy-storage applications.
• High-temperature endurance: Rated for operation from −40°C to +125°C with a specified lifetime of 2000 hours at 125°C (φ12.5 case), supporting sustained thermal stress.
• Reliability & Qualification: AEC-Q200 qualified and RoHS compliant, reflecting series-level suitability for automotive electronics and regulated environments.
• Loss and leakage characteristics: Specified tan δ of 0.20 (max) and leakage current of 320 µA, enabling predictable dissipation and leakage behavior at the rated voltage.
• Ripple handling: Ripple current ratings provided for multiple frequencies (128 mA at 120 Hz; 230.4 mA at 100 kHz), supporting decoupling and smoothing under AC/ripple loads.
• Package & mounting: Radial lead can with φ12.5 × 20 mm dimensions and 5 mm lead spacing for straightforward through-hole assembly and secure mechanical retention.
• Packaging: Supplied in bulk packaging suitable for volume assembly processes.

Typical Applications

• Automotive electronics — Suited for heavy-duty automobile electronics where high temperature endurance and AEC-Q200 qualification are required.
• High-temperature power circuits — Designed for power-supply filtering and energy storage in circuits that operate up to +125°C.
• High-voltage smoothing — 250 V rating and 22 µF capacitance for smoothing and decoupling in higher-voltage electronic subsystems.

Unique Advantages

• High-voltage capability: 250 V rating provides design headroom for higher-voltage power rails without changing capacitor topology.
• Thermal durability: Specified for 2000 hours at +125°C (φ12.5 case), enabling longer service life in elevated-temperature environments.
• Automotive-grade qualification: AEC-Q200 rated, giving designers an explicitly qualified choice for automotive and other high-reliability systems.
• Predictable electrical behavior: Defined tan δ and leakage current values support accurate thermal and leakage budgeting in power designs.
• Through-hole robustness: Radial can package with 5 mm lead spacing and φ12.5×20L size offers secure mechanical mounting and easy replacement or prototyping.
• Regulatory compliance: RoHS compliant for designs requiring restricted-substance conformance.
