UHD1A101MDD

The UHD1A101MDD is a radial-lead aluminum electrolytic capacitor specified at 100 µF and 10 V, designed for general-purpose electronic use. It is part of Nichicon's UHD series focused on lower impedance and high ripple capability in a compact radial can package.

Key attributes include low dissipation factor, measurable low-frequency and high-frequency ripple current ratings, a compact φ5 × 11 mm case, and an operating temperature range from −40°C to 105°C. The part is RoHS compliant and supplied in bulk or bag packaging.

Key Features

• Capacitance & Voltage: 100 µF nominal capacitance with a rated voltage of 10 V and ±20% tolerance (at 120 Hz, 20°C).
• Low Impedance / High Ripple Capability: Designed for lower impedance at high frequency with a tangent of loss angle (tan δ) of 0.19 (120 Hz, 20°C) and ripple current ratings of 175 mA at 120 Hz and 250 mA at 100 kHz.
• Leakage & Dissipation: Low leakage current specified at 10 µA (after 2 minutes' application of rated voltage at 20°C) and a defined tan δ value for predictable dissipation behavior.
• Temperature & Endurance: Rated to operate from −40°C to 105°C with a life/endurance specification of 2000 hours at 105°C.
• Compact Radial Package: φ5 × 11 mm can with radial lead mounting, lead spacing 2 mm (±0.5 mm), and available in Bulk (no terminal forming) or Bag packing.
• Compliance: RoHS compliant as specified in the product data.

Typical Applications

• General-purpose electronics: Intended for general-purpose use where a polarized 100 µF, 10 V radial capacitor is required.
• High-ripple circuits: Suitable for circuits that demand measurable ripple handling thanks to specified low- and high-frequency ripple current ratings.
• Space-constrained designs: The compact φ5 × 11 mm case and radial lead format make it appropriate for assemblies with limited board area.

Unique Advantages

• Measurable ripple capability: Defined ripple current values at both 120 Hz (175 mA) and 100 kHz (250 mA) let engineers size parts with frequency-specific ripple in mind.
• Predictable dissipation behavior: Specified tan δ (0.19 at 120 Hz, 20°C) and leakage current (10 µA) provide repeatable electrical characteristics for design validation.
• Compact radial form factor: Small φ5 × 11 mm can and 2 mm lead spacing help preserve board area while keeping through-hole mounting simplicity.
• Wide temperature range and endurance: −40°C to 105°C rating with a 2000-hour endurance at 105°C supports designs that require elevated-temperature operation.
• RoHS compliance: Conforms to RoHS directive as indicated in the product information.

Why Choose UHD1A101MDD?

UHD1A101MDD positions itself as a compact, radial aluminum electrolytic capacitor offering measurable low-frequency and high-frequency ripple performance combined with predictable dissipation and leakage characteristics. Its small φ5 × 11 mm can, 2 mm lead spacing, and radial mounting make it a practical choice for designs that need a polarized electrolytic solution with defined ripple-handling and endurance at elevated temperature.

This part is suited to engineers and procurement teams specifying general-purpose polarized capacitors where clear electrical specifications (capacitance, voltage, tan δ, leakage current, ripple current, and temperature endurance) are required for design verification and BOM definition.
