UPT2P181MHD

The UPT2P181MHD is a miniature aluminum electrolytic capacitor from Nichicon’s UPT series, designed for radial-lead through-hole assemblies. It delivers 180 µF at a 220 V rating in a compact can-style package and is polarized for DC applications.

Engineered for general-purpose power electronics and ballast applications, the UPT2P181MHD combines high ripple-current capability with long-life performance, supporting designs that require robust filtering and power-conditioning over a wide temperature range.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance at a rated voltage of 220 V with ±20% tolerance for predictable charge storage in power circuits.
• High Ripple-Current Handling — Rated ripple currents include 670 mA at 120 Hz and 1.072 A at 10 kHz, enabling effective smoothing under AC ripple and switching conditions.
• Long High-Temperature Life — Endurance specified as 5000 hours at 105°C under rated DC bias plus rated ripple current, supporting extended operation in hot environments.
• Wide Operating Temperature — Specified for use from −40°C to +105°C to accommodate a broad set of ambient conditions.
• Radial Lead, Can Package — Through-hole radial-lead construction and compact dimensions (L: 3.05 × D: 1.6 cm) for easy PCB mounting in traditional power assemblies.
• Polarized Design — Polar capacitor suitable for DC applications where correct polarity is maintained.
• RoHS Compliant — Meets RoHS requirements for lead-free materials.

Typical Applications

• Ballast and lighting power supplies — Provides high ripple-current filtering and energy storage appropriate for ballast circuits as noted in the UPT series description.
• General-purpose power electronics — Suited for decoupling and smoothing in power-supply sections where a compact, high-voltage electrolytic is needed.
• High-frequency ripple environments — With specified ripple ratings at both 120 Hz and 10 kHz, useful where switching or higher-frequency ripple is present.

Unique Advantages

• High ripple capability: Explicit ripple current ratings at 120 Hz and 10 kHz allow designers to size capacitors against measured ripple for reliable thermal performance.
• Compact footprint: Small can dimensions (L: 3.05 × D: 1.6 cm) reduce board space compared with larger high-voltage electrolytics while maintaining substantial capacitance.
• Extended endurance at elevated temperature: 5000-hour rating at 105°C provides measurable lifecycle performance for designs deployed in warm operating environments.
• Wide operating range: −40°C to +105°C operating temperature supports deployment across a variety of ambient conditions.
• Through-hole ease-of-use: Radial lead configuration simplifies assembly and replacement in through-hole PCBs and prototyping fixtures.
• Standards-aligned materials: RoHS compliance helps meet regulatory restrictions on hazardous substances.
