UHW1A123MHD

The UHW1A123MHD is a radial lead aluminum electrolytic capacitor in Nichicon’s UHW series designed for high ripple current and high reliability in a compact can package. It delivers 12,000 µF capacitance at a 10 V rating with a polarized radial-lead form factor and is offered in bulk or bag packing for production supply.

Engineered for general-purpose applications, this capacitor combines low impedance and elevated ripple handling with a long endurance rating, making it suitable where compact high-capacitance energy storage and robust thermal performance are required.

Key Features

• High Capacitance – 12,000 µF: Provides substantial bulk energy storage at a 10 V rated voltage with capacitance tolerance of −20% to +20% for general-purpose designs.
• High Ripple Current Capability: Rated for 3.57 A at 120 Hz (low frequency) and 4.2 A at 10 kHz (high frequency), supporting applications with elevated ripple demands.
• Low Impedance: Specified impedance of 30 mOhm for improved performance at higher frequencies and reduced voltage drop under ripple conditions.
• Extended Endurance: Life/endurance rated at 10,000 hours at 105°C, allowing for prolonged operation under elevated temperature stress.
• Wide Operating Temperature Range: −40°C to +105°C rated operating range to accommodate varied thermal environments.
• Compact Radial Can Package: Size φ16 × 35.5L with 7.5 mm lead spacing and a radial lead mounting type for through-hole PCB designs; available without terminal forming in bulk or bag packing.
• Leakage and Loss Characteristics: Leakage current specified at 1,200 µA and tan δ (DF) of 0.4 under the specified measurement condition (20°C, 120 Hz), providing predictable electrical behavior for design margining.
• RoHS Compliant: Conforms to RoHS requirements for environmental compliance.

Typical Applications

• General-Purpose Power Filtering: Bulk capacitance and high ripple current capability make this part suitable for smoothing and decoupling in general-purpose power circuits.
• High-Ripple Circuits: Where repeated AC ripple is present, the capacitor’s high ripple ratings and low impedance help manage thermal and electrical stress.
• Compact Through-Hole Designs: Radial-lead can configuration and φ16×35.5L size fit applications requiring through-hole mounting with limited board area.

Unique Advantages

• Substantial Bulk Energy Storage: 12,000 µF at 10 V reduces the need for multiple smaller capacitors to achieve equivalent capacitance.
• Designed for Elevated Ripple: Specified ripple currents at both low and high frequencies allow predictable performance in demanding ripple environments.
• Predictable Low-Frequency and High-Frequency Behavior: Low impedance (30 mOhm) and documented tan δ give engineers measurable parameters for simulations and stability analysis.
• Long Endurance at High Temperature: 10,000-hour rating at 105°C supports designs that require long-term reliability under thermal load.
• Compact Radial Package and Packaging Options: φ16 can with 7.5 mm lead spacing in bulk or bag packing simplifies procurement and assembly planning for through-hole manufacturing.
• Regulatory Compliance: RoHS compliance supports environmental and regulatory requirements for many product lines.
