UPJ1V151MPD

The UPJ1V151MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial‑lead can designed for demanding power‑filtering roles. It delivers 150 µF at 35 V in a compact φ8 × 15 mm package with 3.5 mm lead spacing.

Engineered for low impedance and long life under elevated temperature, this UPJ series part is particularly well suited for switching power supplies and other general‑purpose power applications that require stable capacitance, controlled loss (tanδ), and measurable ripple handling.

Key Features

• Capacitance & Voltage — 150 µF rated capacitance at 35 V for bulk decoupling and energy storage in compact assemblies.
• Low Loss — tanδ = 0.12 measured at 20°C, 120 Hz, supporting stable AC performance in filtering applications.
• Ripple Current Capability — 224.1 mA at 120 Hz (low frequency) and 415 mA at 200 kHz (high frequency), enabling effective smoothing in both low‑ and high‑frequency power stages.
• Leakage Current — Specified leakage current of 157.5 µA for predictable standby and bias behavior.
• High Temperature Endurance — Rated for 3000 hours at +105°C (φ8 case), supporting extended life in thermally demanding environments.
• Compact Radial Package — φ8 × 15 mm can with 3.5 mm lead spacing (±0.5 mm) and radial‑lead mounting for through‑hole assembly and robust mechanical retention.
• Wide Operating Range — Operates from −55°C to +105°C, covering a broad set of industrial and electronic use cases.
• RoHS Compliant — Conforms to RoHS directive requirements for lead‑free assembly environments.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to suit production and prototyping workflows.

Typical Applications

• Switching Power Supplies — Input/output smoothing and bulk decoupling where low impedance and ripple handling are required.
• DC‑DC Converters — Energy storage and output filtering in board‑mounted power regulators.
• Industrial Power Modules — Local decoupling and transient suppression in compact power assemblies operating at elevated temperatures.
• Consumer and Commercial Electronics — General purpose power filtering in devices that require small, reliable electrolytic capacitors.

Unique Advantages

• Measurable Low Impedance — Specified tanδ and ripple current values help predict AC performance and thermal behavior in power circuits.
• High‑Temperature Reliability — 3000‑hour endurance at +105°C (φ8 case) supports longer service life in hot operating environments.
• Compact Footprint — φ8 × 15 mm can delivers 150 µF in a small radial‑lead package to minimize board space without sacrificing capacitance.
• Dual Frequency Ripple Support — Rated ripple current at both 120 Hz and 200 kHz enables use across legacy and high‑frequency switching topologies.
• Through‑Hole Robustness — Radial lead format facilitates mechanical strength and simple through‑hole assembly for hand or wave solder processes.
• RoHS Compliance — Suitable for lead‑free manufacturing environments and regulatory requirements.
