UPW2W2R2MPD

The UPW2W2R2MPD is a miniature aluminum electrolytic capacitor from Nichicon's UPW series, configured as a radial-lead can for through-hole mounting. It provides 2.2 µF of capacitance at a 450 V rating, targeting high-voltage decoupling and energy-storage needs in compact switching power supply and automotive electronics designs.

Designed for demanding environments, this polarized capacitor combines a small footprint (approximately 2 cm × 1 cm) with low impedance characteristics, specified ripple current performance, and AEC-Q200 qualification for reliability in automotive applications.

Key Features

• Capacitance and Voltage: 2.2 µF capacitance rated at 450 V for high-voltage bulk or decoupling applications where a compact capacitor is required.
• Miniature Radial Package: Radial lead, can-style package with 5 mm lead spacing and physical dimensions around 2 cm × 1 cm to save board area in compact power assemblies.
• Temperature and Endurance: Operating temperature range of −25°C to +105°C with a specified lifetime of 5000 hours at 105°C, supporting sustained operation at elevated temperatures.
• Low Impedance / Ripple Handling: Specified low-frequency ripple current of 29 mA at 120 Hz and high-frequency ripple current of 46.4 mA at 10 kHz to support switching-regulator ripple demands.
• Tolerance and Polarity: Polarized construction with a capacitance tolerance of −20% to +20% for predictable circuit behavior.
• AEC-Q200 Rated: Qualification to AEC-Q200 provides an established reliability baseline for automotive electronic systems.

Typical Applications

• Switching Power Supplies: High-voltage decoupling and energy storage in compact SMPS designs where board space is limited and low impedance is required.
• Automotive Electronics: Use in automotive control modules and power electronics where AEC-Q200 qualification and elevated-temperature endurance are required.
• High-Voltage Compact Designs: Integration into compact power conversion or filtering stages that require a 450 V-rated capacitor with a small footprint.

Unique Advantages

• High Voltage Capability: 450 V rating enables use on higher-voltage rails without resorting to physically larger capacitors.
• Compact Footprint: Approximately 2 cm × 1 cm size with 5 mm lead spacing reduces PCB area compared with larger bulk capacitors.
• Automotive-Grade Reliability: AEC-Q200 rating supports designs intended for automotive environments and helps simplify reliability planning.
• Designed for Ripple Performance: Specified ripple current values at 120 Hz and 10 kHz indicate suitability for both low- and high-frequency switching ripple conditions.
• Long-Term High-Temperature Endurance: 5000 hours at 105°C provides a measurable endurance metric for thermal-stress assessments.
