UBY1E432MHL

The UBY1E432MHL is a Nichicon UBY series miniature aluminum electrolytic capacitor in a radial-lead can. It delivers 4300 µF at 25 V in a compact φ18 × 20 mm package with 7.5 mm lead spacing, optimized for high-temperature, high-ripple applications.

Designed for demanding environments, this polarized capacitor supports operation from −40 °C to 135 °C, offers AEC-Q200 qualification, and targets automotive and power-control applications that require high capacitance, low impedance, and extended endurance.

Key Features

• Capacitance and Voltage — 4300 µF nominal capacitance rated at 25 V with ±20% tolerance (−20% to +20%).
• High-temperature endurance — Rated for operation from −40 °C to 135 °C with an endurance specification of 3000 hours at 125 °C or 135 °C depending on rated voltage.
• High ripple current capability — Low-frequency ripple current 1.4025 A at 120 Hz and high-frequency ripple current 1.87 A at 100 kHz, enabling robust smoothing in power circuits.
• Low equivalent series resistance (ESR) — 30 mΩ measured at 100 kHz (20 °C), supporting lower losses and improved high-frequency performance.
• Leakage current and dissipation factor — Specified leakage current 3225 µA and tan δ (DF) of 0.2 at 20 °C, 120 Hz for this part.
• Package and mounting — Radial lead can (φ18 × 20 mm), lead spacing 7.5 mm (±0.5 mm), available as bulk (no terminal forming) or bag packing for assembly flexibility.
• Standards and compliance — AEC-Q200 qualified and RoHS compliant, suitable for regulated environments requiring recognized component qualifications.

Typical Applications

• Automotive control modules — Used in automobile control circuits such as electric power steering and direct injection engine drive where high capacitance and high ripple tolerance are required.
• Power-supply smoothing — Bulk energy storage and smoothing for DC rails in high-temperature power electronics.
• High-temperature electronics — Circuits operating up to 135 °C that require stable capacitance and long-term endurance under DC bias and ripple current.

Unique Advantages

• High capacitance in a compact can — 4300 µF in a φ18 × 20 mm package reduces board area compared with larger discrete solutions.
• Designed for elevated temperatures — Specified operation to 135 °C and endurance rated for 3000 hours at elevated temperature for extended service life in hot environments.
• High ripple handling with low ESR — 1.87 A ripple at 100 kHz combined with 30 mΩ ESR minimizes heating and voltage drop under dynamic loads.
• AEC-Q200 qualification — Meeting AEC-Q200 provides a recognized reliability baseline for automotive and transportation electronics designs.
• Radial-lead form factor — Simple through-hole mounting and 7.5 mm lead spacing support straightforward insertion and mechanical robustness in assemblies.
• Regulatory compliance — RoHS compliant for use in designs targeting restricted-substance requirements.
