UHE1V122MHD6

The UHE1V122MHD6 is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's UHE series designed for high-reliability, long-life applications. It provides 1200 µF capacitance at a 35 V rating in a compact φ16 × 20 mm can with 7.5 mm lead spacing.

Engineered for general-purpose electronic equipment, this part delivers low impedance, elevated ripple current capability, and extended endurance—making it suitable where sustained DC bias, bulk energy storage, and thermal durability are required within the specified operating range.

Key Features

• Capacitance & Voltage: 1200 µF nominal capacitance with a 35 V rated voltage and a tolerance of ±20% (–20%~20%), offering substantial bulk capacitance in a compact footprint.
• Low Impedance Performance: Rated impedance of 78 mΩ supports lower AC voltage drop under ripple conditions, helping to stabilize power rails and reduce thermal stress.
• High Ripple Current Capability: Low-frequency ripple current of 2.024 A (120 Hz) and high-frequency ripple current of 2.53 A (10 kHz), enabling reliable filtering and smoothing under AC ripple loads.
• Long Life and Reliability: Designed for 10,000 hours endurance at 105°C, providing extended operational lifetime under elevated temperature and bias conditions.
• Temperature Range: Rated for operation from –40°C to +105°C to accommodate a wide range of ambient conditions.
• Leakage and Dissipation: Leakage current specified at 420 µA and tangent of loss angle (tan δ) of 0.12 (20°C, 120 Hz), useful metrics for predictable power loss and self-heating calculations.
• Package & Mounting: Radial lead (can) package, physical size φ16 × 20L mm, lead spacing 7.5 mm (±0.5 mm), supplied in bulk or bag packing for straightforward through-hole assembly.
• Regulatory Compliance: RoHS compliant, matching modern material-restriction requirements.

Typical Applications

• General-Purpose Power Filtering — Bulk capacitance and rated ripple current make the UHE1V122MHD6 suitable for smoothing and decoupling in power supplies and regulators.
• Energy Storage for Short-Term Loads — Compact 1200 µF capacity supports hold-up and transient current demands in compact electronic modules.
• High-Temperature Electronics — 10,000-hour endurance at 105°C provides predictable lifetime in systems operating at elevated temperatures.

Unique Advantages

• High Endurance Specification: 10,000 hours at 105°C offers long-term reliability for designs subjected to continuous thermal stress.
• Measured Low Impedance: 78 mΩ impedance improves ripple handling and reduces voltage drop across the capacitor under load.
• Dual-Frequency Ripple Capability: Clear ripple ratings at both 120 Hz and 10 kHz (2.024 A and 2.53 A respectively) let engineers assess behavior across common ripple spectra.
• Compact, Through-Hole Form Factor: φ16 × 20 mm radial can with 7.5 mm lead spacing balances board-space efficiency with robust mechanical mounting for through-hole assemblies.
• Quantified Loss and Leakage: Specified tan δ (0.12) and leakage current (420 µA) support thermal and power-loss budgeting during design validation.
• RoHS Compliant: Material compliance simplifies regulatory review and supports environmental requirements.
