UPM1A392MHD

The UPM1A392MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can. It provides 3900 µF capacitance at a 10 V rating with a compact φ12.5 × 40 mm package and 5 mm lead spacing for through-hole mounting.

Designed for demanding environments, the UPM series emphasizes low impedance, high ripple-current capability and extended life at elevated temperatures, making this part suitable for automotive and other industrial power applications that require robust energy storage and smoothing.

Key Features

• Capacitance & Voltage — 3900 µF capacitance with a 10 V rated voltage and ±20% tolerance for bulk energy storage and decoupling in low-voltage power rails.
• Low Impedance — Impedance of 24 mΩ supports low-loss filtering and fast transient response in power systems.
• High Ripple Current Handling — Low-frequency ripple current 3.425 A (120 Hz) and high-frequency ripple current 2.21 A (200 kHz) to handle both bulk and switching ripple in power converters.
• High Reliability Endurance — Rated for 5000 hours at 105°C, providing long-term stability under elevated temperature and bias conditions.
• Wide Operating Temperature — Specified for −55°C to +105°C to accommodate harsh thermal environments.
• Radial Through-Hole Package — φ12.5 mm can, 40 mm length, 5 mm lead spacing, radial lead format for easy insertion and secure mechanical mounting; packaged in bulk or bag packing (no terminal forming).
• Polarized Construction — Polar capacitor suitable for DC applications where polarity is maintained.
• Quality & Compliance — AEC-Q200 qualified and RoHS compliant for adoption in regulated and automotive-grade designs.

Typical Applications

• Automotive Power Electronics — Smoothing and bulk energy storage in low-voltage DC/DC converters and power modules where AEC-Q200 qualification is required.
• Power Supply Filtering — Bulk decoupling and ripple suppression on input/output rails of industrial and consumer power supplies.
• Motor Drives and Inverters — Energy buffering and smoothing for drives and motor-control electronics exposed to elevated temperatures.
• Battery Management & Energy Storage — Charge/discharge smoothing and transient support in battery-fed systems and energy-management circuits.

Unique Advantages

• High ripple current tolerance: Supports both low- and high-frequency ripple (3.425 A @120 Hz; 2.21 A @200 kHz), enabling reliable filtering across switching frequencies.
• Extended high-temperature life: 5000-hour endurance at 105°C reduces maintenance and replacement frequency in high-heat installations.
• Compact, serviceable form factor: φ12.5 × 40 mm radial can with 5 mm lead spacing for simple through-hole assembly and robust solder/joint reliability.
• Low impedance performance: 24 mΩ impedance delivers lower losses and improved transient response compared to higher-impedance alternatives.
• Automotive-capable quality: AEC-Q200 qualification and an application listing for automotive signal that the part meets demanding reliability criteria for vehicle systems.
• Regulatory compliance: RoHS compliance supports use in designs targeting global environmental regulations.
