UVC2G180MPD

The UVC2G180MPD is an aluminum electrolytic capacitor in an ultra‑miniature radial can package optimized for adapter circuits and general‑purpose power applications. It is a polarized, radial‑lead component offering 18 µF capacitance at a 400 V rating in a compact 10 × 20 mm case.

The part is RoHS‑compliant and designed for through‑hole assembly where a high voltage capacitor in a reduced case size is required. Note: this product is scheduled to be discontinued and is not recommended for new designs.

Key Features

• Capacitance and Tolerance — 18 µF nominal capacitance with ±20% tolerance at 120 Hz, 20 °C.
• High Voltage Rating — Rated for 400 V operation suitable for high‑voltage adapter circuits.
• Ultra‑Miniature Can — Compact radial can dimensions: φD × L = 10 × 20 mm; one rank smaller case size than the UVY series, making it suitable where board space is constrained.
• Temperature and Endurance — Operating range −40 °C to +105 °C with an endurance specification of 2000 hours at 105 °C under rated DC bias plus rated ripple current.
• Ripple Current Capability — Rated ripple current: 200 mA at 120 Hz and 300 mA at 10 kHz (typical frequency behavior: coefficient 1.00 at 120 Hz and 1.50 at ≥10 kHz for 10–18 µF values).
• Leakage and Dissipation — Leakage current specified by I = 0.04CV + 100 (µA) after 1 minute at 20 °C; tan δ (dissipation factor) max 0.25 at 120 Hz, 20 °C.
• Mounting and Marking — Radial lead, polarized can; printed marking in white on a dark brown sleeve for polarity and part identification.
• RoHS Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Adapters — Bulk and smoothing capacitor in external AC‑DC adapters where a compact 400 V capacitor is required.
• Switch‑Mode Power Supplies — DC link or filtering roles in through‑hole designs that need high voltage handling in a reduced footprint.
• General‑Purpose Power Electronics — Voltage smoothing and ripple suppression in compact power modules and consumer electronics adapter circuits.

Unique Advantages

• Compact high‑voltage solution: Provides 400 V capability in a 10 × 20 mm can, enabling smaller adapter and power supply designs.
• Designed for adapter circuits: Series intent and dimensioning (one rank smaller than UVY) make it suitable for space‑constrained adapter layouts.
• Operational robustness at elevated temperature: Rated for continuous operation up to 105 °C with a 2000‑hour endurance specification under rated conditions.
• Through‑hole, polarized package: Radial leads simplify assembly and rework in traditional PCB manufacturing processes.
• Predictable AC performance: Specified ripple currents at 120 Hz and 10 kHz and defined frequency coefficients for design calculation.
• Regulatory compliance: RoHS‑compliant construction supports environmental regulatory requirements.

Why Choose UVC2G180MPD?

The UVC2G180MPD positions itself as a compact, high‑voltage aluminum electrolytic option for adapter and general‑purpose power applications where board space is limited but 400 V capability is needed. Its combination of 18 µF capacitance, radial lead package, and elevated‑temperature endurance (2000 h at 105 °C) provides a verifiable choice for designers balancing size and electrical requirements.

Because this part is supplied in a standard radial can with clear sleeve marking and RoHS compliance, it integrates straightforwardly into existing through‑hole production flows for refurbishment, repair, or legacy designs. Please note the part is scheduled for discontinuation and is not recommended for new designs.
