UPJ1E151MPD

The UPJ1E151MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPJ series, offering a 150 µF capacitance at 25 V in a compact φ8 × 11.5 mm can. Designed for low impedance performance and high reliability, this part is well suited for switching power supplies and general-purpose power filtering in through-hole applications.

Key Features

• Electrical Performance 150 µF nominal capacitance with ±20% tolerance and a tangent of loss angle (tan δ) of 0.14 at 25 V provides predictable impedance behavior for power circuits.
• Voltage Rating Rated for 25 V DC to support a wide range of low-voltage power designs.
• Ripple Handling Specified ripple currents of 172.8 mA at 120 Hz (low frequency) and 320 mA at 200 kHz (high frequency) enable effective smoothing of both line-frequency and switching ripple.
• Leakage Current Initial leakage current specified at 112.5 µA, supporting tight bias stability after application of rated voltage.
• Reliability & Endurance Rated life of 3000 hours at 105°C for the φ8 case size, with endurance tests defined under DC bias plus rated ripple current.
• Temperature Range Operates from −55°C to +105°C to cover a broad range of environmental conditions.
• Mechanical & Mounting Radial-lead, polarized can in a φ8 × 11.5 mm package with 3.5 mm lead spacing (±0.5 mm) for straightforward through-hole assembly.
• Packaging & Compliance Available in bulk (no terminal forming) or bag packing and RoHS compliant for regulatory adherence.

Typical Applications

• Switching Power Supplies — Low impedance characteristics and specified ripple current make this capacitor suitable for output filtering and decoupling in switching regulators.
• General-Purpose Power Filtering — 150 µF capacitance and 25 V rating provide energy storage and smoothing for a wide range of electronic equipment.
• Through-Hole/PCB Power Modules — Radial-lead package and compact φ8 can are optimized for through-hole mounting where robust mechanical retention is required.

Unique Advantages

• Low-impedance series design: Series positioning for low impedance supports tighter voltage ripple control in switching applications.
• High-temperature endurance: 3000 hours at +105°C (φ8 case) provides measurable reliability for elevated-temperature deployments.
• Clear ripple specifications: Separate low- and high-frequency ripple current ratings (172.8 mA at 120 Hz, 320 mA at 200 kHz) help engineers size capacitors to real operating conditions.
• Compact through-hole form factor: φ8 × 11.5 mm can with 3.5 mm lead spacing offers a space-efficient solution for PCB power sections.
• Regulatory and supply convenience: RoHS compliance and mass-production status simplify procurement and regulatory planning.
• Flexible packing options: Bulk or bag packing accommodates automated or manual assembly workflows.
