UHE1V221MPD

The UHE1V221MPD is a miniature, radial‑lead aluminum electrolytic capacitor from Nichicon’s UHE series designed for high reliability and low impedance in general‑purpose electronic designs. It delivers 220 µF capacitance at a 35 V rating with a compact φ8 × 15 mm can and polarized radial leads for through‑hole mounting.

Engineered for applications that require sustained performance at elevated temperature, this part offers long endurance (7,000 hours at 105 °C for 16–100 V ratings within the UHE series), defined ripple handling and controlled leakage for stable power filtering and bulk decoupling in embedded and industrial electronics.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 35 V rated voltage and capacitance tolerance of -20% to +20% for predictable energy storage and decoupling.
• Low Impedance — Specified impedance of 350 mOhm and a tanδ (loss tangent) of 0.12 measured at 20 °C, 120 Hz, supporting effective AC ripple attenuation and stable performance.
• Ripple Current Capability — Low‑frequency ripple current 588 mA (120 Hz) and high‑frequency ripple current 840 mA (10 kHz), suitable for smoothing and ripple suppression in power stages.
• Long Endurance — Rated life of 7,000 hours at 105 °C (applies across the UHE series for 16–100 V ratings), providing longevity in elevated-temperature applications.
• Compact Radial Package — φ8 × 15 mm can with radial leads and 3.5 mm lead spacing (±0.5 mm tolerance), available in bulk (no terminal forming) or bag packing for production and prototyping workflows.
• Controlled Leakage & Polarization — Leakage current specified at 77 µA and polarized construction for correct orientation in DC circuits.
• Operating Temperature Range — Rated for -40 °C to +105 °C to cover a wide range of environmental conditions.
• RoHS Compliance & Production Status — RoHS compliant and in mass production for reliable supply and regulatory alignment.

Typical Applications

• Power Supply Filtering — Bulk smoothing and ripple reduction in linear and switching power supplies where 35 V rating and 220 µF storage are required.
• DC/DC Converter Output — Output decoupling and energy buffering for converters that demand defined ripple‑current handling at both low and high frequencies.
• Embedded and Industrial Electronics — General‑purpose decoupling and energy storage in boards and modules operating across -40 °C to 105 °C.
• General‑Purpose Energy Storage — Local bulk capacitance for transient load support and hold‑up in a variety of electronic designs.

Unique Advantages

• Compact footprint with significant capacitance — φ8 × 15 mm can provides 220 µF storage in a small through‑hole package for space‑constrained designs.
• Verified ripple performance — Explicit low‑ and high‑frequency ripple current ratings (588 mA at 120 Hz; 840 mA at 10 kHz) let designers size capacitors based on measured ripple conditions.
• Long operational life at elevated temperature — 7,000‑hour endurance at 105 °C (series specification for 16–100 V) supports deployments in thermally demanding environments.
• Low loss and stable impedance — tanδ of 0.12 and 350 mOhm impedance contribute to efficient filtering and reduced heat under ripple load.
• Production‑ready packaging — Available in bulk (no terminal forming) or bag packing to match manufacturing and prototype requirements.
• Regulatory compliance — RoHS‑compliant construction aligns with common environmental directives.
