UPW1E151MPD

The UPW1E151MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPW series, engineered for miniature, low-impedance power applications. It delivers 150 µF at 25 V in a compact φ8 × 11.5 mm can with 3.5 mm lead spacing.

Designed for switching power supplies and automotive electronics, this part combines low impedance, rated ripple performance at both low and high frequencies, and a 3000-hour endurance at 105°C with AEC-Q200 qualification for demanding environments.

Key Features

• Capacitance & Voltage — 150 µF rated capacitance with a 25 V rating and ±20% tolerance, suitable for bulk decoupling and power smoothing.
• Low Impedance — Specified impedance of 234 mΩ, providing reduced voltage ripple under load.
• High Ripple Capability — Low-frequency ripple current of 360.75 mA (120 Hz) and high-frequency ripple current of 555 mA (10 kHz), supporting both mains-frequency and switching-frequency applications.
• Loss Characteristics — tanδ = 0.14 measured at 20°C and 120 Hz, enabling predictable dissipation behavior in designs.
• Reliability & Endurance — 3000 hours endurance at 105°C; leakage current specified at 112.5 µA to aid reliability assessments.
• Automotive-Grade Qualification — AEC-Q200 rating, indicating suitability for automotive electronics where that qualification is required.
• Compact Radial Package — φ8 × 11.5 mm can, radial leads with 3.5 mm spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing; mass-production status for procurement stability.
• Wide Temperature Range — Operating range from −55°C to +105°C for use across broad thermal environments.

Typical Applications

• Switching Power Supplies — Bulk and output smoothing where low impedance and high ripple capability improve transient response and reduce voltage ripple.
• Automotive Electronics — Power filtering and decoupling in electronic control units and sensor interface modules, leveraging AEC-Q200 qualification and extended temperature range.
• Embedded Power Modules — Local energy storage and smoothing in compact DC–DC converters and power management boards where board space is limited.

Unique Advantages

• Space-efficient energy storage: 150 µF in a φ8 × 11.5 mm can reduces PCB area while maintaining useful capacitance for power rails.
• Measurable ripple performance at switching frequencies: 555 mA ripple rating at 10 kHz supports high-frequency switching applications without speculative claims.
• Engineered for reliability: 3000-hour endurance at 105°C with defined leakage current and tanδ makes it straightforward to model lifetime and degradation.
• Automotive-capable qualification: AEC-Q200 rating supports deployment in automotive systems that require qualified passive components.
• Standard radial footprint: 3.5 mm lead spacing and common radial can format simplify replacement and prototype evaluation.
• Production-ready supply: Mass production status with bulk and bag packing options eases sourcing for prototypes and production runs.

Why Choose UPW1E151MPD?

The UPW1E151MPD is positioned for compact power designs that require predictable ripple handling, low impedance, and verified endurance at elevated temperature. Its combination of 150 µF/25 V capability, measured impedance and ripple specifications, and AEC-Q200 qualification make it a practical choice for switching power supplies and automotive electronics where size, thermal tolerance, and lifecycle data matter.

Engineers specifying this capacitor benefit from clear, measurable parameters—impedance, tanδ, leakage, ripple ratings, and a 3000-hour endurance—that support design validation, reliability planning, and supply continuity.
