UBY2A301MHL

The UBY2A301MHL is a miniature, high-reliability radial lead aluminum electrolytic capacitor from the UBY series. It delivers 300 µF capacitance at a 100 V rating in a compact φ12.5 × 30.5 mm can, engineered for applications that require high ripple tolerance and extended operation at elevated temperatures.

Designed for demanding environments, this AEC-Q200 qualified, RoHS-compliant unit combines low ESR, high ripple current capability and wide temperature capability to support power conditioning and smoothing in systems that operate up to 135°C.

Key Features

• Capacitance & Voltage — 300 µF nominal capacitance with a 100 V rated voltage and tolerance of -20% to +20% for stable bulk energy storage.
• High Temperature Operation — Rated for operation from -40°C to 135°C, with endurance specified to 2000 hours at 135°C under rated conditions.
• Low Impedance / Low ESR — ESR of 42 mΩ measured at 20°C / 100 kHz, supporting efficient high-frequency performance.
• High Ripple Current Capability — Low-frequency ripple current 1.315 A (120 Hz) and high-frequency ripple current 2.63 A (100 kHz) to handle demanding power ripple loads.
• Leakage & Dissipation — Leakage current specified at 900 µA and tanδ (DF) of 0.08 at 20°C/120 Hz, aiding predictable loss and self-heating behavior.
• Package & Mounting — Radial lead (can) package with 5.0 mm lead spacing (±0.5 mm) for through-hole assemblies; available in bulk or bag packing.
• Automotive-Grade Qualification — AEC-Q200 rated for use in automotive electronic applications requiring component qualification to that standard.

Typical Applications

• Automotive control circuits — Suited for vehicle systems such as electric power steering and direct injection engine drive as called out in the product series specification.
• High-temperature power electronics — Bulk energy storage and smoothing where operation at up to 135°C and elevated ripple currents are required.
• Power conditioning — Decoupling and smoothing in power supplies and converters that demand low ESR and stable performance at high frequency.

Unique Advantages

• High ripple tolerance: Rated ripple currents of 1.315 A (120 Hz) and 2.63 A (100 kHz) reduce heating under dynamic power loads.
• Wide operating temperature: Specified performance from -40°C to 135°C supports designs exposed to elevated ambient temperatures.
• Low ESR at high frequency: 42 mΩ ESR at 100 kHz improves transient response and reduces losses in high-frequency circuits.
• AEC-Q200 qualification: Provides component-level qualification for automotive-grade system design and acceptance testing.
• Compact radial package: φ12.5 × 30.5 mm can with standard 5.0 mm lead spacing simplifies through-hole assembly in space-constrained boards.
• RoHS compliant: Meets RoHS requirements for restricted substances in electronic components.
