UPJ2A271MHD6

The UPJ2A271MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPJ series. It is a radial-lead, polarized component offering 270 µF capacitance at a 100 V rated voltage, designed for use where low impedance and long life are required.

Designed with switching power supplies and general-purpose power circuits in mind, this part provides specified ripple current capability, controlled loss (tan δ), and extended endurance for demanding thermal environments up to +105°C.

Key Features

• Capacitance & Voltage: 270 µF rated capacitance at 100 V for energy storage and smoothing in higher-voltage circuits.
• Low Loss (tan δ): tan δ = 0.08 measured at 20°C, 120 Hz and 100 V, providing controlled dissipation for power applications.
• Ripple Current Capability: Low-frequency ripple current 523.3 mA (120 Hz) and high-frequency ripple current 918 mA (200 kHz) for handling switching and AC ripple.
• Leakage Current: Specified leakage current of 810 µA, supporting predictable bias behavior after voltage application.
• High Endurance: Rated life/endurance 5000 hours at 105°C, enabling longevity in elevated-temperature load conditions.
• Wide Temperature Range: Operating range from −55°C to +105°C for use across varied thermal environments.
• Compact Radial Package: Case size φ18 × 20 mm, lead spacing 7.5 mm (±0.5 mm), radial-lead mounting for through-hole assemblies.
• Compliance & Packaging: RoHS compliant; available in bulk (no terminal forming) and bag packing for flexible procurement.

Typical Applications

• Switching Power Supplies: Low impedance and specified ripple current ratings make the UPJ2A271MHD6 suitable for output filtering and energy buffering in switching regulators.
• General-Purpose Power Circuits: 270 µF at 100 V provides bulk capacitance for smoothing and decoupling in a wide range of general-purpose designs.
• Compact Through-Hole Power Modules: The φ18 × 20 mm radial can and 7.5 mm lead spacing fit compact PCB layouts and modular power assemblies needing reliable through-hole capacitors.

Unique Advantages

• Long Thermal Endurance: 5000 hours rated life at +105°C supports sustained operation in elevated-temperature applications, reducing maintenance and replacement frequency.
• Engineered for Switching Environments: Series-level design emphasis on low impedance and suitability for switching power supplies ensures stable performance under switching ripple.
• Measurable Loss Characteristics: Low tan δ (0.08 at 100 V, 20°C, 120 Hz) gives predictable ESR-related behavior for power designers.
• Defined Ripple Handling: Explicit ripple current ratings at low and high frequencies (523.3 mA at 120 Hz; 918 mA at 200 kHz) allow designers to size capacitors to expected operating conditions.
• Compact, Standardized Footprint: φ18 × 20 mm can size with 7.5 mm lead spacing simplifies mechanical integration in through-hole layouts.
• RoHS Compliant: Conforms to RoHS requirements for regulated material content.
