UBX1K221MHL

The UBX1K221MHL is a radial-lead aluminum electrolytic capacitor offering 220 µF capacitance at a rated voltage of 80 V. Built for high-temperature, long-life operation, this component is designed for demanding automotive and heavy-duty electronics where elevated operating temperatures and reliable performance are required.

Key value propositions include a wide operating temperature range to +150°C, AEC-Q200 rating, long endurance (2000 h at 150°C), and measurable ripple-current capability for both low- and high-frequency applications.

Key Features

• High Temperature Range – Rated for operation from −55°C to +150°C, enabling use in elevated-temperature environments.
• Capacitance & Voltage – 220 µF nominal capacitance with ±20% tolerance and an 80 V rated voltage for higher-voltage DC link and power applications.
• Long Endurance – 2000 hours life at 150°C under rated ripple and DC bias, supporting extended service in heavy-duty applications.
• Ripple Current Handling – Low-frequency ripple current 837.5 mA at 120 Hz and high-frequency ripple current 1.25 A at 100 kHz to support smoothing and decoupling across a range of switching frequencies.
• Low Dissipation Factor – tan δ = 0.08 (measured at 20°C, 120 Hz, 80 V), indicating controlled dielectric losses under nominal conditions.
• Leakage Current – Specified leakage current 528 µA, providing predictable leakage behavior for design margin calculations.
• Radial Can Package – Compact φ16 × 25 mm can with 7.5 mm lead spacing (±0.5 mm) for through-hole mounting and secure mechanical retention.
• Reliability & Compliance – AEC-Q200 rating and RoHS compliance for use in regulated automotive supply chains.

Typical Applications

• Automotive electronics – Power supply smoothing and decoupling in control modules and electronic assemblies exposed to high ambient temperatures.
• High-temperature power systems – Bulk energy storage and ripple filtering where components must withstand sustained elevated temperatures.
• DC–DC converter inputs – Input-side decoupling for converters that require stable capacitance and ripple handling at higher voltages and temperatures.

Unique Advantages

• High-temperature capability: Operates up to +150°C, enabling deployment in under-hood and other high-thermal-stress locations.
• Designed for endurance: 2000-hour rated life at 150°C supports prolonged reliability in heavy-duty applications.
• AEC-Q200 qualified: Addresses automotive development requirements and helps streamline qualification in vehicle electronics.
• Measurable ripple performance: Specified low- and high-frequency ripple currents (837.5 mA at 120 Hz, 1.25 A at 100 kHz) allow confident thermal and reliability budgeting.
• Compact through-hole form factor: φ16 × 25 mm radial can with 7.5 mm lead spacing provides a balance of capacitance and PCB footprint for rugged assemblies.
• Predictable electrical losses: Low tan δ (0.08 at 80 V, 120 Hz) aids in estimating dielectric dissipation in system-level thermal models.
