UPW1V122MHD

The UPW1V122MHD is a miniature aluminum electrolytic capacitor from Nichicon’s UPW series designed for low-impedance, high-reliability power applications. As a radial-lead, can-style polarized capacitor rated at 35 V and 1.2 mF, it targets demanding switching power supply and automotive electronics environments.

Engineered for durability, the part carries an AEC-Q200 rating and delivers specified ripple current performance across low and high frequencies, combined with a wide operating temperature range to support robust power filtering and decoupling in compact assemblies.

Key Features

• Capacitance & Voltage — 1.2 mF capacitance at a 35 V rated voltage for bulk energy storage and smoothing in power circuits.
• Low Impedance — 50 mΩ impedance reduces voltage drop and loss under load, improving DC rail stability.
• High Ripple Current Capability — Specified ripple handling of 1.964 A at 120 Hz and 2.31 A at 10 kHz to support switching supply workloads.
• Automotive-Grade Reliability — AEC-Q200 rating for use in automotive electronics requiring industry-recognized qualification.
• Radial, Through-Hole Package — Radial lead, can-style package with 5 mm lead spacing for traditional PCB mounting and robust mechanical connection.
• Wide Temperature & Long Life — Operating range from –55°C to +105°C with a rated life of 7000 hours at 105°C.
• Polarized Construction — Polar capacitor suitable for DC smoothing and bulk decoupling where polarity is maintained.
• Compact Footprint — Small physical size (L: 3.05 × D: 1.25 cm) for space-constrained designs.

Typical Applications

• Switching Power Supplies — Bulk filtering and decoupling in switching regulators where low impedance and high ripple capability improve transient response.
• Automotive Electronics — Power smoothing and energy storage in automotive subsystems that require AEC-Q200–rated components.
• Power Modules & Assemblies — Through-hole radial mounting for rugged connections in power delivery modules and industrial controllers.
