UPJ1J271MHD6

The UPJ1J271MHD6 is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPJ series, engineered for low-impedance performance in power conversion applications. It provides 270 µF capacitance at a 63 V rating in a compact φ18 × 15 mm can, suitable for through-hole radial mounting.

Designed for general-purpose use and specifically indicated for switching power supplies, this capacitor combines high ripple-current capability and long-term endurance for reliable operation in demanding power circuits.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a rated voltage of 63 V and a tolerance of −20% to +20% (120 Hz, 20 °C).
• Low-impedance construction — UPJ series specification denotes low impedance behavior, optimized for power-supply applications.
• Loss angle (tan δ) — tan δ = 0.08 (measured at 20 °C, 120 Hz), supporting stable performance under AC ripple conditions.
• High ripple-current capability — Rated ripple current: 550.05 mA at 120 Hz (low frequency) and 965 mA at 200 kHz (high frequency), enabling effective smoothing in switching environments.
• Leakage current — Specified leakage current of 510.3 µA after standard application of rated voltage.
• Endurance — 5000 hours load life at 105 °C, matching UPJ series long-life characteristics for sustained operation at elevated temperature.
• Temperature range — Operates from −55 °C to +105 °C for broad environmental compatibility.
• Radial can package — φ18 × 15 mm package with 7.5 mm lead spacing (±0.5 mm), available in bulk or bag packing; mounting type: radial lead (polarized).
• RoHS compliant — Conforms to RoHS directive requirements (as stated for the series).

Typical Applications

• Switching power supplies — Low impedance and high ripple-current ratings make it suitable for output smoothing and energy buffering in switch-mode supplies.
• General-purpose power circuits — 270 µF capacitance and 63 V rating provide bulk capacitance for a variety of through-hole designs requiring polarized electrolytic capacitors.
• High-temperature operating environments — With 5000-hour endurance at 105 °C and an operating range down to −55 °C, it is appropriate where elevated ambient temperature reliability is required.

Unique Advantages

• Engineered for switching environments: The UPJ series' low-impedance profile and specified high-frequency ripple current (965 mA at 200 kHz) support effective performance in modern switch-mode topologies.
• Long-term thermal endurance: 5000-hour rated life at 105 °C provides predictable aging characteristics for designs that must withstand sustained elevated temperatures.
• Measurable electrical stability: Low tan δ (0.08 at 63 V, 120 Hz) and defined leakage current (510.3 µA) give clear, verifiable parameters for circuit designers to use in simulations and reliability assessments.
• Compact radial can footprint: φ18 × 15 mm can and standard 7.5 mm lead spacing simplify board layout for through-hole assemblies while delivering substantial capacitance.
• Production-ready availability: Listed as mass production with bulk and bag packing options to support volume procurement and assembly workflows.
