UPJ1J271MHD

The UPJ1J271MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPJ series. It is a radial-lead, low-impedance capacitor designed for demanding power-management roles.

With a rated capacitance of 270 µF at 63 V, a wide operating temperature range of -55 °C to 105 °C and long endurance (5,000 hours at 105 °C), this part is well suited for switching power supplies and general-purpose power filtering in industrial and electronic designs that require compact, durable bulk capacitance.

Key Features

• Capacitance & Voltage: 270 µF nominal capacitance with a rated voltage of 63 V and tolerance of -20% to +20%, providing defined energy storage for power rails.
• Low Loss / Low Impedance: Tangent of loss angle (tan δ) specified at 0.08 (measured at 20 °C, 120 Hz), supporting efficient filtering and reduced heating under AC conditions.
• High Ripple Capability: Rated low-frequency ripple current 570 mA at 120 Hz and high-frequency ripple current 1.0 A at 200 kHz, enabling handling of both mains-frequency and switching-frequency currents.
• Long Endurance: Load-life specification of 5,000 hours at +105 °C for the applicable case size, delivering predictable long-term performance in elevated-temperature environments.
• Leakage Current: Specified leakage current 510.3 µA, suitable for many power-supply and bulk-decoupling applications where controlled leakage is required.
• Compact Radial Can Package: 12.5 mm diameter × 25 mm length (φ12.5 × 25L) with 5 mm lead spacing (±0.5 mm), radial lead mounting for through-hole assemblies and straightforward placement.
• Temperature Range & Reliability: Operating from -55 °C to +105 °C with RoHS compliance, supporting use across a wide range of environmental conditions.
• Packaging Options: Available in bulk (no terminal forming) or bag packing to suit production and prototyping workflows.

Typical Applications

• Switching Power Supplies: Low impedance and defined ripple-current capability make it suitable for output smoothing and bulk storage in switch-mode power supplies.
• DC–DC Converters: Compact radial package and high ripple handling help stabilize converter outputs and reduce voltage ripple on intermediate rails.
• Industrial Power Electronics: Long endurance at 105 °C and wide temperature range support sustained operation in industrial control and power distribution modules.
• General-Purpose Power Filtering: Provides bulk capacitance and decoupling for a variety of consumer and professional electronic assemblies requiring reliable through-hole components.

Unique Advantages

• Robust High-Temperature Endurance: 5,000-hour load-life rating at +105 °C ensures predictable aging and service life in hot operating conditions.
• Designed for Switching Environments: Low impedance characteristics and specified tan δ at 20 °C/120 Hz support efficient filtering in switching supplies.
• Dual-Frequency Ripple Support: Separate low- and high-frequency ripple current ratings (570 mA at 120 Hz and 1.0 A at 200 kHz) provide clear guidance for both mains and switching-frequency applications.
• Compact, Through-Hole Form Factor: φ12.5 × 25 mm can with 5 mm lead spacing offers a balance of capacitance density and easy PCB mounting for retrofit or new designs.
• Controlled Leakage Behavior: Specified leakage current value (510.3 µA) aids designers in budgeting standby and quiescent currents in power systems.
• RoHS Compliant: Meets RoHS requirements, simplifying regulatory compliance for end products.
