UPW1J151MPD

The UPW1J151MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's UPW series designed for low-impedance, high-reliability power applications. With a 150 µF capacitance at a 63 V rating and a compact φ10×16L can, it targets switching power supplies, DC–DC converters and automotive electronic modules that require sustained ripple handling and wide operating temperatures.

Key Features

• Capacitance and Tolerance — 150 µF nominal capacitance with capacitance tolerance −20% to +20% (measurement basis 120 Hz, 20 °C).
• Rated Voltage — 63 V rated voltage suitable for mid-voltage power rails and converter outputs.
• Low Loss / Low Impedance — tanδ of 0.09 (measured at 20 °C, 120 Hz) and specified impedance of 388 mΩ for improved transient response in high-frequency power circuits.
• Ripple Current Capability — Frequency-characterized ripple handling with 429 mA at 120 Hz (low frequency) and 660 mA at 10 kHz (high frequency) to support switching environments.
• Leakage Current — Specified leakage current of 283.5 µA, supporting predictable bias behavior in power designs.
• High Reliability and Endurance — Rated for 5000 hours at 105 °C and compliant with AEC-Q200, addressing reliability needs for demanding electronics.
• Wide Operating Temperature — Operates from −55 °C to +105 °C for extended environmental range.
• Compact Radial Package — φ10×16L can with 5 mm lead spacing (±0.5 mm) in radial-lead format; available in bulk (no terminal forming) or bag packing for production flexibility.

Typical Applications

• Switching Power Supplies — Low impedance and high ripple capability make the capacitor suitable for output filtering and decoupling in switching regulators.
• DC–DC Converters — Compact size and robust ripple performance support bulk and decoupling functions on converter outputs and intermediate rails.
• Automotive Electronics — AEC-Q200 rating, wide temperature range and 5000-hour endurance at 105 °C address durability requirements in automotive control modules and power systems.
• Power Management Modules — Stable tanδ and controlled leakage current help maintain predictable behavior in power distribution and sequencing circuits.

Unique Advantages

• Predictable performance under load: Specified impedance, tanδ and leakage current provide designers with clear electrical parameters for power-stage stability and filtering decisions.
• Designed for switching environments: High-frequency ripple current rating (660 mA at 10 kHz) and low impedance support sustained operation in switch-mode power converters.
• Automotive-capable reliability: AEC-Q200 compliance and a 5000-hour life rating at 105 °C deliver a documented reliability profile for demanding applications.
• Wide temperature tolerance: The −55 °C to +105 °C operating range enables use across harsh thermal environments and varied system locations.
• Compact, assembly-friendly form factor: φ10×16L radial can with standardized 5 mm lead spacing and bulk/bag packing options eases PCB layout and production handling.
