UHE1C121MED

The UHE1C121MED from Nichicon is a radial-lead aluminum electrolytic capacitor in the UHE series, specified at 120 µF and 16 V. It is a polarized, miniature can-style capacitor designed for general-purpose board-level power filtering and decoupling in compact assemblies. Key value propositions include a compact φ6.3 × 11 mm package, defined ripple-current capability across low and high frequencies, and a wide operating temperature range from −40 °C to 105 °C.

Key Features

• Electrical Characteristics — 120 µF capacitance with tolerance −20% to +20% and rated at 16 V. Specified tan δ is 0.16 at 20 °C, 120 Hz.
• Ripple Current Performance — Rated low-frequency ripple current of 238 mA at 120 Hz and high-frequency ripple current of 340 mA at 10 kHz, enabling board-level smoothing across a range of switching and line frequencies.
• Leakage Current — Specified leakage current of 19.2 µA (measured after rated voltage application), suitable for general-purpose power applications where low quiescent drain is important.
• Temperature and Endurance — Operating range −40 °C to 105 °C with a life/endurance rating of 5000 hours (as specified for this part).
• Compact Radial Package — φ6.3 × 11 mm can with 2.5 mm lead spacing (±0.5 mm). Radial lead form factor simplifies through-hole mounting and prototyping.
• Compliance and Packaging — RoHS compliant. Available in Bulk (no terminal forming) and Bag packing options for handling flexibility.

Typical Applications

• General-purpose power filtering — Bulk decoupling and smoothing on low-voltage power rails where 16 V rating and 120 µF capacitance are required.
• DC–DC converter output smoothing — Board-level output filter capacitor for compact converters, utilizing the specified ripple current capability at both low and high frequencies.
• Embedded and industrial electronics — Through-hole mounting in compact assemblies that require operation across −40 °C to 105 °C.

Unique Advantages

• Compact footprint: Small φ6.3 × 11 mm can saves PCB space while providing substantial capacitance for board-level energy storage.
• Frequency-flexible ripple handling: Published ripple current figures at 120 Hz and 10 kHz give designers clear parameters for both line-frequency and switching-frequency applications.
• Wide operating temperature range: Rated from −40 °C to 105 °C, enabling use across a broad set of environmental conditions.
• Standard radial-lead form: Through-hole leads with 2.5 mm spacing simplify assembly and prototyping on conventional PCBs.
• RoHS compliant: Meets RoHS requirements for materials compliance.
