UHW1V122MHD

The UHW1V122MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can intended for general-purpose power applications. It delivers 1200 µF at a 35 V rating with a compact φ12.5 × 25 mm case and radial mounting for through-hole designs.

Designed for applications that require high ripple handling and stable operation at elevated temperatures, this part offers low impedance at high frequencies, a long endurance rating at 105°C, and RoHS compliance.

Key Features

• Electrical Performance — 1200 µF capacitance at 35 V with a tolerance of -20% to +20% and an impedance of 45 mΩ, providing substantial bulk capacitance and low-loss performance in compact footprints.
• High Ripple Current — Low-frequency ripple current of 1.92 A (120 Hz) and high-frequency ripple current of 3.2 A (10 kHz), enabling robust ripple handling across a wide frequency range.
• Loss and Leakage — Tangent of loss angle (tanδ) specified at 0.11 (120 Hz, 20°C) and a leakage current of 420 µA, supporting predictable loss and leakage behavior for power designs.
• Reliability & Endurance — Rated for 10,000 hours at 105°C, with endurance limits defined for capacitance change, tanδ increase, and leakage current to support long-term operation.
• Temperature Range — Operational from -40°C to 105°C, suitable for electrically demanding environments requiring wide temperature capability.
• Compact Radial Package — φ12.5 mm diameter by 25 mm length with 5 mm lead spacing (±0.5 mm tolerance), radial lead mounting and can-style package for through-hole assemblies; available in bulk (no terminal forming) or bag packing.
• Series-Level Design Traits — Series notes indicate lower impedance at high frequency and a smaller case size paired with high ripple current characteristics, useful for space-constrained power stages.
• RoHS Compliance — Conforms to RoHS requirements for restricted substances.

Typical Applications

• General Purpose Power Filtering — Provides bulk energy storage and ripple suppression where high ripple current and compact size are required.
• Power Supply and Converter Support — Suited for smoothing and decoupling on power rails that operate up to 35 V and require reliable performance at elevated temperature.
• Industrial and Electronic Equipment — Appropriate for equipment requiring components rated for long endurance (10,000 h at 105°C) and wide operating temperatures.

Unique Advantages

• High Ripple Capacity: 1.92 A (120 Hz) and 3.2 A (10 kHz) ripple ratings reduce the need for parallel components when managing AC ripple and switching noise.
• Low Impedance in a Small Footprint: 45 mΩ impedance and a φ12.5 × 25 mm package deliver significant capacitance and low loss while conserving board area.
• Long-Term Thermal Endurance: 10,000-hour rating at 105°C provides predictable lifetime characteristics for designs exposed to sustained elevated temperatures.
• Predictable Electrical Losses: Specified tanδ (0.11 at 120 Hz, 20°C) and defined leakage current (420 µA) support reliable thermal and power-loss budgeting.
• Flexible Packing Options: Available in bulk (no terminal forming) or bag packing to match assembly and handling preferences.
• Regulatory Compliance: RoHS-compliant construction supports use in regions and projects requiring restricted-substance conformity.
