UHD1V122MHD

The UHD1V122MHD is a radial-lead aluminum electrolytic capacitor offering 1,200 µF capacitance at a 35 V rating with ±20% tolerance. It is designed for general-purpose electronic applications that require high ripple-current handling and long operational life.

Built for reliability in power circuits, the device combines low-loss performance (tan δ 0.12) with specified low- and high-frequency ripple currents, RoHS compliance, and endurance under elevated temperature stress.

Key Features

• Capacitance & Voltage: 1,200 µF nominal capacitance at 35 V with ±20% tolerance, suitable for bulk energy storage and decoupling in general-purpose designs.
• Low Loss (tan δ): Specified tan δ of 0.12 at 120 Hz, supporting efficient energy handling and reduced heating under AC ripple.
• High Ripple Current Capability: Rated ripple current of 2.632 A at 120 Hz and 3.29 A at 100 kHz, enabling effective performance across low and high frequency power domains.
• Controlled Leakage Current: Specified leakage current of 420 µA, providing predictable standby performance after voltage application.
• Endurance at Elevated Temperature: 5,000 hours lifetime at 105°C under rated conditions, delivering long-term stability in thermally demanding environments.
• Operating Temperature Range: −40°C to +105°C, accommodating a wide range of ambient conditions.
• Radial Lead Package: φ12.5 can with 5 mm lead spacing, radial lead mounting for through-hole assembly; available in bulk (no terminal forming) or bag packing for mass production.
• RoHS Compliant: Conforms to RoHS directive, suitable for restricted-substance requirements.
• Low Impedance at High Frequency: Series-level characteristic of reduced impedance in higher frequency ranges, supporting applications with high-frequency ripple currents.

Typical Applications

• Power Supply Filtering: Bulk filtering and smoothing in power supplies where 35 V ratings and high ripple current capability are required.
• DC Bus & Energy Storage: Decoupling and local energy storage in general-purpose electronics to support transient loads.
• Industrial Control Electronics: Use in control and power circuitry requiring long endurance at elevated temperature (5,000 h at 105°C).

Unique Advantages

• High Ripple Endurance: Elevated ripple current ratings at both low and high frequencies reduce stress on the capacitor and improve system reliability under dynamic loads.
• Long-Term Thermal Reliability: 5,000-hour endurance at 105°C supports sustained operation in hot ambient conditions and thermally stressed designs.
• Predictable Electrical Performance: Specified tan δ and leakage current values enable predictable loss and standby characteristics for power budgeting and thermal design.
• Through-Hole Robustness: Radial-lead, φ12.5 can and 5 mm lead spacing provide a stable mechanical connection for through-hole assemblies and mass-production handling.
• Regulatory Compliance: RoHS compliance helps meet environmental and procurement requirements without additional screening.
