UPW1A122MPD

The UPW1A122MPD is a miniature aluminum electrolytic capacitor from Nichicon’s UPW series, optimized for switching power supply applications. It provides 1.2 mF capacitance at a 10 V rating in a compact radial-can package with low impedance and engineered reliability for demanding environments.

Designed for applications including automotive electronics, this radial-lead capacitor combines measurable low impedance, defined ripple-current capability, and AEC-Q200 qualification to support long-term operation across a wide temperature range.

Key Features

• Capacitance & Voltage — 1.2 mF capacitance rated at 10 V, suitable for bulk decoupling and energy storage in power rails.
• Low Impedance — Specified impedance of 104 mΩ, enabling effective ripple suppression and improved transient response in switching supplies.
• Ripple Current Performance — Rated ripple current of 1.037 A at 120 Hz and 1.22 A at 10 kHz, supporting both low- and high-frequency switching environments.
• Automotive-Grade Reliability — AEC-Q200 rated for applications that require recognized passive component qualification.
• Wide Temperature Range — Operates from −55 °C to +105 °C to cover automotive and industrial ambient conditions.
• Long Life at Elevated Temperature — 5000 hours specified at 105 °C, providing predictable endurance for prolonged high-temperature use.
• Radial Lead, Can Package — Through-hole radial lead configuration with 5 mm lead spacing for straightforward PCB mounting and assembly.
• Compact Footprint — Small physical size (approx. 2 × 1 cm) for space-constrained designs where board real estate is limited.

Typical Applications

• Switching Power Supplies — Bulk smoothing and ripple suppression for DC–DC converters and SMPS front-ends.
• Automotive Power Modules — Decoupling and energy buffering in automotive electronic control units and power distribution modules where AEC-Q200 qualification is required.
• DC Bus and Rail Filtering — Stabilizing power rails and absorbing switching transients in compact power electronics.

Unique Advantages

• Compact, high-capacitance solution — 1.2 mF in a small radial-can package reduces board area while delivering required bulk capacitance.
• Measured low impedance — 104 mΩ impedance helps lower voltage ripple and improves converter stability without adding extra components.
• Frequency-aware ripple capability — Rated ripple current values at both 120 Hz and 10 kHz ensure useful performance across common switching frequencies.
• Automotive-grade qualification — AEC-Q200 rating supports use in regulated automotive electronics and other demanding systems.
• Wide operating temperature — −55 °C to +105 °C enables deployment across harsh ambient conditions.
• Predictable lifetime — 5000 hours at 105 °C gives designers a clear endurance target for thermal-stressed applications.
