UPW2A2R2MDD

The UPW2A2R2MDD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UPW series, engineered for low impedance and high reliability. It is a polarized, through-hole component intended for compact power applications and switching power supplies.

With a 2.2 µF capacitance at 100 V rating, a wide operating temperature range of −55 °C to 105 °C, and AEC-Q200 categorization, this capacitor is specified for demanding environments that require durable, space-efficient power filtering and decoupling.

Key Features

• Electrical Performance — 2.2 µF capacitance with ±20% tolerance (120 Hz, 20 °C) and a rated voltage of 100 V for wide DC rail support.
• Low Loss — Tangent of loss angle (tan δ) of 0.08 measured at 20 °C, 120 Hz, supporting efficient energy handling in power circuits.
• Ripple Handling — Low-frequency ripple current of 13.2 mA (120 Hz) and high-frequency ripple current of 44 mA (10 kHz) to address both bulk and high-frequency ripple components.
• Leakage Current — Leakage current specified at 6.6 µA for predictable standby behavior and low quiescent loss.
• Reliability and Endurance — Endurance rated at 2000 hours at 105 °C, and AEC-Q200 rating for heightened reliability in regulated environments.
• Compact Radial Package — Small form factor φ5 × 11 mm with 2 mm lead spacing and radial lead mounting for easy through-hole assembly and prototyping.
• Wide Temperature Range — Specified operation from −55 °C to 105 °C to meet a broad set of thermal environments.

Typical Applications

• Switching Power Supplies — Provides low-impedance filtering and decoupling in compact DC–DC converter and switching regulator stages.
• Automotive Electronic Modules — AEC-Q200 categorization and broad temperature range support use in automotive control and accessory electronics.
• Power Filtering in Industrial Electronics — Suitable for local decoupling and ripple suppression on intermediate and high-voltage rails.
• Compact Power Designs — Small φ5 × 11 mm package enables space-efficient placement in dense layouts requiring 100 V capability.

Unique Advantages

• Compact footprint, high voltage: 100 V rating in a φ5 × 11 mm can saves board space while accommodating higher DC rails.
• Measurable low loss: tan δ = 0.08 at 120 Hz gives predictable impedance and thermal behavior for power-stage design.
• Designed for ripple management: Specified ripple currents at both low and high frequencies help control heat and extend service life under dynamic loads.
• Automotive-grade reliability: AEC-Q200 categorization and 2000-hour endurance at 105 °C support use in regulated and temperature-stressed applications.
• Through-hole convenience: Radial lead mounting and 2 mm lead spacing simplify prototyping, repair, and certain assembly flows.

Why Choose UPW2A2R2MDD?

The UPW2A2R2MDD combines a high 100 V rating with a compact radial package and low-loss characteristics, making it well suited for engineers designing compact power stages and filtering networks that must operate across −55 °C to 105 °C. Its specified ripple currents, low leakage, and AEC-Q200 categorization provide a clear, verifiable basis for inclusion in reliability-focused designs.

This part is ideal for applications that require predictable electrical performance in a small through-hole form factor, including switching power supplies and automotive electronic modules where endurance at elevated temperature is required.
