UPW1E102MHD

The UPW1E102MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can, designed for demanding power applications. With a rated capacitance of 1000 µF and a 25 V rating, it targets switching power supplies and automotive power electronics where low impedance, high ripple handling and long life are required.

Manufactured by Nichicon and offered in mass-production quantities, the UPW1E102MHD combines compact size (φ12.5 × 20 mm) and through-hole radial mounting (5 mm lead spacing) with endurance and thermal range suitable for robust designs.

Key Features

• Capacitance & Voltage — 1000 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance, providing bulk energy storage for decoupling and hold-up functions.
• Low Impedance Performance — Specified impedance of 76 mΩ supports low-loss filtering in high-current switching environments.
• High Ripple Current Capability — Rated ripple current of 1.245 A at 120 Hz and 1.66 A at 10 kHz to handle both low- and high-frequency switching ripple.
• High Reliability & Long Life — Endurance rated to 7000 hours at 105°C, suitable for extended operation in elevated-temperature systems.
• Wide Operating Temperature — Specified for −55°C to +105°C to maintain performance across harsh thermal conditions.
• Electrical Characteristics — Loss tangent (tan δ) of 0.14 (measured at 20°C, 120 Hz) and leakage current of 750 µA, delivering predictable behavior for precision power designs.
• Package & Mounting — Radial lead, aluminum can package (φ12.5 × 20 mm) with 5 mm lead spacing and bulk/bag packing options for flexible assembly and inventory handling.
• AEC-Q200 Rated — Meets AEC-Q200 qualification noted in the product data for use in automotive-grade applications where applicable.

Typical Applications

• Switching Power Supplies — Bulk and output filtering in DC–DC converters and SMPS, where low impedance and high ripple current reduce voltage ripple and heating.
• Automotive Power Electronics — Energy storage and smoothing in vehicle power modules and control units, leveraging AEC-Q200 qualification and wide temperature capability.
• Power Management Modules — Decoupling and hold-up capacitors in industrial and embedded power systems that require long endurance and compact footprint.

Unique Advantages

• Compact, high-capacity form factor — 1000 µF in a φ12.5 × 20 mm can saves board space while delivering substantial bulk capacitance.
• Robust ripple handling — High ripple current ratings at both 120 Hz and 10 kHz reduce self-heating and extend service life in switching environments.
• Designed for elevated temperatures — 7000-hour endurance at 105°C supports long-term reliability in thermally demanding applications.
• Predictable electrical behavior — Characterized impedance, tan δ, and leakage current values aid accurate power-system modeling and thermal design.
• Automotive-capable qualification — AEC-Q200 listing in the product data supports selection for automotive power designs where such qualification is required.
• Through-hole mounting convenience — Radial leads with 5 mm spacing enable straightforward assembly and replacement in power electronics platforms.
