UPW1H151MPD

The UPW1H151MPD from Nichicon is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for compact power applications. It delivers 150 µF at a 50 V rating with low impedance and defined ripple handling for power-smoothing and switching power supply designs.

Built for demanding thermal and lifetime requirements, this part is specified for operation from −55 °C to 105 °C with a 5,000 hour endurance at 105 °C and carries an AEC-Q200 rating suitable for automotive power electronics and other high-reliability systems.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance at a 50 V rated voltage with ±20% tolerance.
• Low Impedance — Rated impedance of 324 mOhm to support reduced voltage ripple and improved transient response in power rails.
• Ripple Current Handling — Low-frequency ripple current of 399.8 mA at 120 Hz and high-frequency ripple current of 615 mA at 10 kHz for reliable filtering across switching frequencies.
• Leakage & Dissipation Factor — Leakage current specified at 225 µA and tanδ (DF) 0.10 (measured at 20 °C, 120 Hz), enabling predictable performance in DC-bias conditions.
• High Temperature Endurance — Rated for 5,000 hours at 105 °C to meet long-term thermal stress requirements in harsh environments.
• Package & Mounting — Radial-lead can, size Ø10 × 12.5 mm (length), 5.0 mm lead spacing (±0.5 mm), available in bulk or bag packing for through-hole assembly.
• Automotive-Grade Qualification — AEC-Q200 rated, supporting use in automotive power modules and systems where component-level qualification is required.

Typical Applications

• Switching Power Supplies — Bulk and output smoothing where low impedance and reliable ripple handling are required across switching frequencies.
• Automotive Power Electronics — Power modules and control units that demand AEC-Q200 qualification and long-term operation at elevated temperatures.
• DC‑DC Converters and Voltage Rails — Local decoupling and energy buffering on compact boards where radial-lead through-hole mounting is preferred.

Unique Advantages

• Compact, space-efficient form — Ø10 × 12.5 mm can provides substantial capacitance in a small radial-lead package for space-constrained designs.
• Predictable ripple performance — Specified ripple currents at both low and high frequencies (399.8 mA @120 Hz, 615 mA @10 kHz) help designers size capacitors for real switching conditions.
• High-temperature durability — 5,000 hour life at 105 °C supports long-term stability in thermally demanding applications.
• Automotive-grade assurance — AEC-Q200 rating aligns the part with automotive development and qualification processes.
• Through-hole robustness — Radial-lead mounting with 5 mm lead spacing simplifies mechanical retention and replacement in serviceable assemblies.
• Manufacturer availability — Mass-production status from Nichicon supports consistent sourcing for production programs.
