UPW1V270MDD

The UPW1V270MDD is a radial-lead aluminum electrolytic capacitor from the Nichicon UPW series designed for compact, low-impedance power applications. This 27 µF, 35 V polarized capacitor delivers stable performance across a wide temperature range and is designed for board-level power filtering and energy smoothing.

As part of the UPW family, it targets power electronics including switching power supplies and automotive electronic modules where small size, reliable ripple handling and elevated-temperature endurance are required.

Key Features

• Capacitance & Tolerance: 27 µF nominal with tolerance −20% to +20%, suitable for decoupling and filtering in compact power circuits.
• Rated Voltage: 35 V DC rated voltage for mid-voltage power rails and converters.
• Low Loss / Low Impedance: tanδ = 0.12 (measured at 20°C, 120 Hz) for reduced AC loss in switching environments.
• Ripple Current Capability: 54 mA at 120 Hz (low frequency) and 180 mA at 10 kHz (high frequency) to handle both line-frequency and switching ripple components.
• Leakage Current: Specified leakage current of 28.35 µA for predictable standby and bias behavior.
• Temperature & Endurance: Rated for −55°C to 105°C with a listed endurance of 2000 hours at 105°C, supporting elevated-temperature operation.
• Compact Radial Package: φ5 × 11 mm can (size dimension 1.1 × 0.5 cm) with 2.0 mm lead spacing (±0.5 mm) for through-hole assembly and straightforward PCB placement.
• Automotive-Grade Reliability: AEC-Q200 rating and explicit application note for automotive use.
• Packaging Options: Supplied in bulk (no terminal forming) or bag packing for simple handling and manual or automated assembly workflows.

Typical Applications

• Switching Power Supplies: Local energy storage and output filtering to smooth switching ripple and stabilize regulator outputs.
• DC–DC Converters: Input/output decoupling in compact converters where low impedance and high-frequency ripple capability are required.
• Automotive Electronics: Board-level filtering and smoothing in electronic control modules leveraging the part's AEC-Q200 rating and wide temperature range.

Unique Advantages

• Space-efficient form factor: φ5 × 11 mm can and 1.1 × 0.5 cm footprint allow high-density placement on through-hole or mixed-technology boards.
• Balanced ripple handling: Dual ripple current specifications (54 mA at 120 Hz, 180 mA at 10 kHz) address both low- and high-frequency ripple in switching environments.
• Predictable electrical behavior: Low tanδ and specified leakage current support reliable AC performance and bias characteristics for power circuits.
• High-temperature endurance: Rated endurance of 2000 hours at 105°C supports designs that must operate at elevated ambient temperatures.
• Automotive-capable rating: AEC-Q200 qualification signals suitability for automotive electronics designs where that standard is required.
• Through-hole convenience: Radial leads with standard 2.0 mm spacing ease manual assembly, prototyping and certain automated insertion processes.
