UHD1H101MPD

The UHD1H101MPD is an aluminum electrolytic capacitor in a radial lead can, offering 100 µF capacitance at a 50 V rating. It is designed for general-purpose electronic use where compact size, high ripple capability and low high-frequency impedance are important.

Key attributes include low loss (tanδ 0.1 at 50 V, 120 Hz, 20°C), high-frequency ripple performance, a wide operating temperature range of -40°C to 105°C and a rated endurance of 3000 hours at 105°C.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a rated voltage of 50 V and a tolerance of -20% to +20%.
• Low Loss & Frequency Performance — tanδ of 0.10 at 50 V (120 Hz, 20°C) and datasheet-stated lower impedance at high frequency for improved decoupling and ripple handling.
• High Ripple Current — Rated ripple currents of 506.8 mA at 120 Hz and 724 mA at 100 kHz, supporting both low- and high-frequency ripple environments.
• Reliability & Endurance — Endurance specified as 3000 hours at 105°C under DC bias plus rated ripple current, with defined limits for capacitance change, tanδ and leakage after the test.
• Operating Range — Temperature range from -40°C to 105°C to suit a wide range of ambient conditions.
• Radial Lead Package — Compact φ8 × 11.5 mm can with 3.5 mm lead spacing (±0.5 mm), available in bulk or bag packing for assembly flexibility.
• Leakage Current — Specified leakage current of 50 µA (measured after 2 minutes at 20°C per the series specification methodology).
• RoHS Compliant — Meets RoHS requirements as indicated in product data.

Typical Applications

• General-purpose power rail decoupling — 100 µF capacitance and low high-frequency impedance make the UHD1H101MPD suitable for smoothing and decoupling on 50 V rails in general electronic designs.
• Ripple suppression in power supplies — Rated ripple current values at 120 Hz and 100 kHz support suppression of both low- and high-frequency ripple components.
• Bulk energy storage for compact assemblies — Small φ8 × 11.5 mm can and radial-lead format provide bulk capacitance in space-constrained, general-purpose circuits.

Unique Advantages

• High ripple tolerance: Specified ripple currents up to 724 mA at 100 kHz reduce thermal stress and extend service life in ripple-heavy environments.
• Low high-frequency impedance: Series design emphasizes lower impedance at high frequencies, improving decoupling performance for switching circuits.
• Compact radial can: φ8 × 11.5 mm package with 3.5 mm lead spacing delivers significant capacitance in a small footprint for general-purpose board layouts.
• Wide temperature capability: Rated for operation from -40°C to 105°C, enabling use across a broad range of ambient conditions.
• Long rated endurance: 3000 hours at 105°C under rated conditions provides a measurable lifecycle metric for design planning.
• RoHS compliance: Conformance to RoHS supports regulatory requirements for assemblies.
