UPZ2G270MPD

The UPZ2G270MPD is a Nichicon UPZ series aluminum electrolytic capacitor: a 27 µF, 400 V polarized radial‑lead device in a compact φ10 × 30.5 mm can. It is designed for general‑purpose, high‑voltage applications that require a miniature footprint combined with rated performance at elevated temperatures.

This part delivers controlled dissipation (tan δ = 0.15 at 20°C, 120 Hz), defined leakage (532 µA), and rated ripple performance for both low and high frequencies, making it suitable for high‑voltage power circuits and related equipment.

Key Features

• Electrical — Capacitance & Voltage: 27 µF capacitance rated for 400 VDC with a tolerance of −20% to +20%.
• Dissipation Factor (tan δ): tan δ = 0.15 measured at 20°C, 120 Hz (rated voltage), providing predictable loss characteristics for design margining.
• Leakage Current: Specified leakage current of 532 µA (measured after rated voltage application), enabling predictable standby and bias conditions.
• Ripple Current Performance: Rated low‑frequency ripple current 240 mA at 120 Hz and high‑frequency ripple current 360 mA at 10 kHz, supporting both mains‑frequency and higher‑frequency decoupling roles.
• Frequency Coefficient (400 V class): Ripple scaling factors for 400–450 V: 60 Hz = 0.80, 120 Hz = 1.00, 500 Hz = 1.25, 1 kHz = 1.40, 10 kHz+ = 1.50.
• Mechanical — Package & Mounting: Radial lead, polarized can in φ10 × 30.5 mm size with 5 mm lead spacing (±0.5 mm), suitable for through‑hole mounting.
• Temperature & Endurance: Operating range −40°C to +105°C and endurance of 2000 hours at 105°C under rated DC bias plus rated ripple current.
• Packaging & Availability: Supplied in bulk (no terminal forming) or bag packing; product is in mass production.

Typical Applications

• High‑voltage power supplies: Bulk filtering and smoothing in compact, high‑voltage DC power supplies where a small footprint and 400 V rating are required.
• Industrial control equipment: Energy storage and decoupling in control circuits that operate across a wide temperature range (−40°C to +105°C).
• Power conversion modules: Input/output filtering and ripple attenuation in medium‑to‑high voltage power conversion subsystems.
• Measurement and instrumentation: Stable capacitance and controlled tan δ make the part suitable for high‑voltage measurement circuits and test equipment.

Unique Advantages

• Compact high‑voltage form factor: 400 V rating in a miniature φ10 × 30.5 mm can allows space‑constrained high‑voltage designs.
• Predictable loss behavior: Specified tan δ (0.15 at 20°C, 120 Hz) helps with thermal budgeting and AC loss calculations.
• Defined leakage for bias stability: 532 µA leakage current provides a clear basis for standby and bias current planning.
• Ripple performance across frequencies: Rated ripple currents (240 mA at 120 Hz, 360 mA at 10 kHz) and published frequency coefficients enable designers to size capacitors for both low‑ and high‑frequency ripple conditions.
• Wide operating temperature and proven endurance: −40°C to +105°C range with 2000 hours endurance at 105°C under rated stress supports long‑term operation in demanding environments.
• Through‑hole mounting convenience: Radial leads with 5 mm spacing simplify prototyping and PCB replacement in serviceable assemblies.
