UPJ1V270MDD

The UPJ1V270MDD is a Nichicon UPJ-series aluminum electrolytic capacitor in a radial-lead can package, specified at 27 µF and 35 V with polarized construction. It combines a compact φ5 × 11 mm footprint and 2 mm lead spacing for through-hole assemblies with characteristics targeted at general-purpose power filtering and switching power supply applications.

Engineered as part of the UPJ low-impedance family, this capacitor offers controlled dissipation (tan δ 0.12), low leakage, and specified ripple-current capability to support power-rail decoupling and DC–DC converter designs over a −55°C to +105°C operating range.

Key Features

• Electrical Characteristics — 27 µF capacitance rated at 35 V with ±20% tolerance, suitable for common power rail decoupling and bulk-filtering roles.
• Low Loss — Dissipation factor (tan δ) of 0.12 at rated conditions to help minimize AC losses in high-frequency and switching environments.
• Low Leakage Current — Specified leakage current of 28.35 µA after 1 minute at 20°C, limiting standby loss and helping retain charge in low-current circuits.
• Ripple-Current Capability — Rated ripple current of 49.5 mA at 120 Hz and 99 mA at 200 kHz for handling both low-frequency smoothing and higher-frequency switching ripple.
• Thermal and Life Ratings — Operates across −55°C to +105°C with a rated life of 2000 hours at 105°C for reliable elevated-temperature performance.
• Radial Through-Hole Package — φ5 × 11 mm can with 2 mm lead spacing and radial leads for easy insertion and soldering in through-hole boards and prototyping.
• RoHS Compliant — Meets RoHS directive requirements for lead-free compliance in modern electronics assemblies.

Typical Applications

• Switching Power Supplies — Low-impedance UPJ series construction makes this capacitor suitable for output filtering and decoupling in switched-mode supplies.
• General Power Filtering — Used for bulk and smoothing applications on DC rails in consumer and industrial electronics.
• DC–DC Converters — Provides stable capacitance and ripple handling for converter input/output networks in space-constrained through-hole designs.

Unique Advantages

• Compact Through-Hole Footprint: The φ5 × 11 mm can and 2 mm lead spacing minimize board space while preserving through-hole mounting simplicity.
• Designed for Switching Environments: Low tan δ and series-design low-impedance characteristics support effective ripple attenuation in switching applications.
• Reduced Standby Loss: Low specified leakage current (28.35 µA) helps maintain efficiency in low-current or standby conditions.
• Wide Operating Temperature: −55°C to +105°C range enables deployment across varied thermal environments without changing capacitor type.
• Measurable Ripple Performance: Specified ripple currents at 120 Hz and 200 kHz provide clear selection criteria for both low-frequency smoothing and high-frequency switching use cases.
• Regulatory Compliance: RoHS compliance supports use in lead-free product designs and global markets.

Why Choose UPJ1V270MDD?

UPJ1V270MDD positions itself as a compact, through-hole aluminum electrolytic solution for designers who need reliable power filtering in switching and general-purpose applications. Backed by the Nichicon UPJ series design intent for low impedance, it pairs controlled dissipation (tan δ 0.12) and specified ripple/leakage characteristics with a small φ5 × 11 mm can and 2 mm lead spacing.

This part is well suited for engineers and procurement teams specifying capacitors for DC–DC converter outputs, power-supply decoupling, and other board-level power filtering tasks where a proven, space-efficient polarized capacitor with defined life and temperature ratings is required.
