UHE2A221MHD

The UHE2A221MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UHE series. It provides 220 µF nominal capacitance at a 100 V rating in a compact φ12.5 × 30.5 mm can with 5 mm lead spacing.

Designed for general-purpose electronic applications, this capacitor combines low impedance, high ripple-handling capability and long-term endurance to support power filtering and energy-storage needs in demanding designs.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance.
• Low Impedance & Dissipation — Specified impedance of 420 mΩ and tanδ of 0.08 (measured at 20 °C, 120 Hz) for reduced voltage drop and improved AC performance.
• High Ripple Current Capability — Low-frequency ripple current 707 mA (120 Hz) and high-frequency ripple current 1.01 A (10 kHz) to handle a range of ripple profiles.
• Long Life & Wide Temperature Range — Rated endurance of 10,000 hours at 105 °C and an operating temperature range from −40 °C to +105 °C.
• Leakage Current Control — Specified leakage current of 220 µA for predictable standby and bias behavior.
• Radial Lead Package — Radial, can-style package with 5 mm lead spacing and compact diameter/length (φ12.5 × 30.5 mm) for through-hole assemblies.
• RoHS Compliant & Packaging Options — RoHS-compliant construction; supplied in bulk (no terminal forming) or bag packing.

Typical Applications

• General-purpose electronics — Suited for designs that require a 220 µF, 100 V electrolytic capacitor with long life and low impedance.
• Power circuitry — Appropriate where higher voltage rating and ripple capability are needed in general-purpose power circuits.
• Through-hole assemblies — Radial lead form factor and compact can size fit standard through-hole layouts for repairable or robust board designs.

Unique Advantages

• Long-term endurance: 10,000‑hour rating at 105 °C supports longer maintenance intervals and stable performance over time.
• High voltage capability: 100 V rating enables use in higher-voltage general-purpose power rails without series stacking.
• Low impedance and loss: 420 mΩ impedance and tanδ 0.08 at 120 Hz reduce AC losses and improve filtering effectiveness.
• Strong ripple handling: Rated for 707 mA at 120 Hz and 1.01 A at 10 kHz, accommodating a range of ripple-frequency environments.
• Compact radial form factor: φ12.5 × 30.5 mm can with 5 mm lead spacing provides a space-efficient through-hole solution.
• Regulatory and packaging flexibility: RoHS compliance plus bulk or bag packing options ease procurement and assembly planning.
