UKT1H3R3MDD

The UKT1H3R3MDD is a radial-lead aluminum electrolytic capacitor designed for audio and general-purpose electronic applications. It provides 3.3 µF capacitance at a 50 V rating in a compact φ5×11L can with 2 mm lead spacing (±0.5 mm).

Key performance attributes include operation across −55°C to 105°C, a 1000 hour endurance at 105°C, low leakage current, and AEC-Q200 qualification. Status: End Of Life.

Key Features

• Capacitance & Voltage — 3.3 µF nominal capacitance with a rated voltage of 50 V and ±20% tolerance at 120 Hz, 20°C.
• Temperature & Endurance — Wide operating range from −55°C to 105°C and a guaranteed 1000 hours lifetime at 105°C.
• Electrical Losses — Low dissipation factor with tan δ = 0.14 (max) measured at 20°C, 120 Hz for the 50 V rating.
• Leakage & Ripple Performance — Low leakage current specified at 4.95 µA, with ripple current capability of 25 mA at 120 Hz (low frequency) and 50 mA at 10 kHz (high frequency).
• Package & Mounting — Radial lead, polarized aluminum can package (φ5×11L) with 2 mm lead spacing (±0.5 mm) for through-hole mounting.
• Qualification — AEC-Q200 rated for applications requiring higher reliability standards.
• Packaging — Supplied in bulk bag packing (no terminal forming) for easy handling in manual or automated assembly workflows.

Typical Applications

• General Audio Equipment — Filtering, decoupling and smoothing functions in audio power supplies and signal paths where wide temperature tolerance and low leakage matter.
• Audio Power Decoupling — Local supply decoupling in amplifiers and preamps benefiting from specified ripple current and low tan δ at audio-relevant frequencies.
• Embedded Electronics with Through‑Hole Mounting — Compact radial can for designs that require robust through-hole components and dependable long-term performance at elevated temperatures.

Unique Advantages

• Wide operating temperature range — −55°C to 105°C operation and 1000 hour endurance at 105°C support reliable performance in thermally demanding environments.
• Compact radial form factor — φ5×11L can with 2 mm lead spacing provides a small footprint for space-constrained through-hole designs.
• Low electrical loss — tan δ = 0.14 at 20°C/120 Hz helps minimize dissipation in audio-frequency circuits.
• Low leakage current — Specified 4.95 µA leakage current supports stable bias and reduces DC loss in sensitive circuits.
• Broad ripple handling — Defined ripple current ratings (25 mA @120 Hz, 50 mA @10 kHz) give predictable performance across audio and higher-frequency supply ripple conditions.
• Reliability pedigree — AEC-Q200 rating addresses higher reliability needs for regulated or demanding applications.
