UHE2A121MPD

The UHE2A121MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for general-purpose electronic applications. As part of the UHE series, it provides a 120 µF capacitance at a 100 V rating with low impedance and extended endurance for sustained operation at elevated temperatures.

This radial lead component is optimized for power supply filtering and smoothing on medium-voltage rails, offering measurable ripple-handling capability and long life for designs that require compact, reliable capacitance in a cylindrical package (φ10 × 30.5 mm).

Key Features

• Capacitance & Voltage: 120 µF nominal capacitance with a 100 V rated voltage, suitable for medium-voltage filtering and energy storage.
• Miniature Radial Package: φ10 × 30.5 mm can with 5 mm lead spacing (±0.5 mm), radial-lead mounting for through-hole assemblies and easy PCB integration.
• Low Impedance & Loss: Specified impedance of 710 mOhm and tanδ (loss tangent) of 0.08 at 20°C, 120 Hz, supporting efficient AC ripple attenuation.
• Ripple Current Capability: Low-frequency ripple current of 518 mA at 120 Hz and high-frequency capability of 740 mA at 10 kHz, enabling effective ripple handling across typical power-supply frequencies.
• Leakage Current: Leakage current specified at 120 µA, allowing predictable standby and bias behavior in circuits.
• Extended Life & Temperature Range: Rated endurance of 7,000 hours at 105°C and operating range from −40°C to +105°C for long-term reliability under elevated-temperature conditions.
• Polarized Type & Packaging: Polarized aluminum electrolytic design supplied in bulk (no terminal forming) or bag packing; product is in mass production and RoHS compliant.

Typical Applications

• Power Supply Filtering: Smoothing and bulk filtering on medium-voltage DC rails up to 100 V, using its capacitance and ripple-current capability to reduce voltage ripple and stabilize supply nodes.
• DC-DC Converters and Voltage Rails: Output filtering and energy buffering in converter circuits where compact, high-voltage capacitance and low impedance are required.
• General-Purpose Electronics: Through-hole designs requiring a reliable polarized capacitor with predictable leakage, tolerance, and long-life performance across −40°C to +105°C.

Unique Advantages

• High Voltage Capability: 100 V rating enables use on medium-voltage rails without resorting to multiple lower-voltage parts in series.
• Compact Footprint: φ10 × 30.5 mm package delivers 120 µF in a small radial can that eases placement in space-constrained through-hole designs.
• Measured Ripple Performance: Specified low- and high-frequency ripple currents (518 mA at 120 Hz, 740 mA at 10 kHz) provide designers with quantifiable AC handling for power designs.
• Long Endurance at Elevated Temperature: 7,000-hour life at 105°C supports extended field life in thermally demanding environments.
• Predictable Electrical Behavior: Low impedance (710 mOhm), defined tanδ (0.08 at 120 Hz, 20°C) and specified leakage (120 µA) make system-level budgeting and stability analysis more straightforward.
• Regulatory Compliance: RoHS compliant to support environmental requirements in commercial electronic products.
