UBY2A431MHL

The UBY2A431MHL is a polarized aluminum electrolytic capacitor in a radial‑lead can designed for high-temperature use up to 135°C. It delivers 430 µF at 100 V in a compact φ12.5 × 40 mm package with 5 mm lead spacing, targeted at control and power circuitry where high ripple handling and elevated operating temperature are required.

Engineered as part of the UBY series, this capacitor emphasizes low impedance and high ripple current for demanding applications, and is AEC‑Q200 qualified and RoHS compliant. It is available in bulk or bag packing and is in mass production.

Key Features

• Capacitance & Voltage — 430 µF nominal capacitance with a rated voltage of 100 V and tolerance of −20% to +20%.
• High Temperature Operation — Rated for an operating temperature range of −40 °C to 135 °C and endurance specified at elevated temperature.
• High Ripple Current — Supports 1.63 A low‑frequency ripple current (120 Hz) and 3.26 A high‑frequency ripple current (100 kHz) to handle dynamic load conditions.
• Low Impedance / Low ESR — ESR specified at 31 mΩ measured at 20 °C / 100 kHz for improved power performance and reduced loss.
• Reliability & Endurance — Endurance rating of 2000 hours at 135 °C (for 63 to 100 V ratings) with defined limits for capacitance change, tan δ and leakage after life test.
• Mechanical & Mounting — Radial lead can (φ12.5 × 40 mm), lead spacing 5.0 mm (±0.5 mm), available as bulk (no terminal forming) or bag packing.
• Standards & Compliance — AEC‑Q200 qualified and RoHS compliant.

Typical Applications

• Automobile control circuits — Suited for electronic control units where elevated temperature capability and AEC‑Q200 qualification are required.
• Electric power steering systems — Supports duty cycles with high ripple and transient currents common in steering assist electronics.
• Direct injection engine drive — Designed for power conditioning in engine control modules that demand high ripple tolerance and thermal endurance.

Unique Advantages

• High ripple handling: Specified ripple currents of 1.63 A (120 Hz) and 3.26 A (100 kHz) reduce heating under dynamic loads and improve system stability.
• Low ESR at high frequency: 31 mΩ ESR at 100 kHz lowers loss and improves filtering performance in high‑speed power circuits.
• Wide temperature range: −40 °C to 135 °C rating supports deployment in high‑temperature environments while retaining performance.
• AEC‑Q200 qualification: Provides a recognized level of automotive component assessment for designs requiring industry qualification.
• Compact radial form factor: φ12.5 × 40 mm can with 5 mm lead spacing offers a space‑efficient solution for through‑hole power designs.
• Production readiness: Mass production status and standard packaging options (bulk or bag) simplify procurement and assembly planning.
