UPW1J120MDD

The UPW1J120MDD is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can designed for compact power designs. It is part of Nichicon's UPW series, characterized for low impedance and suitability in switching power supply applications.

This unit delivers 12 µF capacitance at a 63 V rating, in a small φ5 × 11 mm package with radial leads and 2 mm lead spacing, offering a space-efficient option for designs that require dependable decoupling and smoothing under elevated temperatures and constrained board area.

Key Features

• Capacitance & Voltage — 12 µF capacitance rated at 63 V with capacitance tolerance of ±20% (–20% to +20%) measured at 120 Hz, 20°C.
• Low Loss / Low Impedance — Tangent of loss angle (tan δ) of 0.09 measured at 20°C, 120 Hz, offering low dissipation for power-filtering applications.
• Ripple Current Performance — Low-frequency ripple current of 43.5 mA at 120 Hz and high-frequency ripple current of 145 mA at 10 kHz, supporting switching power supply ripple handling.
• Leakage & Polarization — Polarized aluminum electrolytic with a measured leakage current of 22.68 µA after rated voltage application conditions.
• Temperature & Endurance — Operating temperature range from –55°C to +105°C with a rated life/endurance of 2000 hours at 105°C.
• Compact Radial Package — Small can size φ5 × 11 mm (0.5 × 1.1 cm) with radial lead form and 2 mm lead spacing (±0.5 mm tolerance); available in bulk (no terminal forming) or bag packing.
• AEC‑Q200 Rated — Series-level AEC‑Q200 rating indicated in the product data, supporting use in applications requiring established passive-component qualification.

Typical Applications

• Switching Power Supplies — Low impedance and specified ripple current values make this capacitor suitable for output filtering and decoupling in compact switch-mode power supplies.
• Automotive Electronics — AEC‑Q200 rating and wide temperature range (–55°C to +105°C) fit automotive electronic modules that require reliable power smoothing.
• DC‑DC Converters and Power Modules — Compact radial form and steady performance at high frequency support use in small power conversion modules where board space is limited.
• Sensors and Control Electronics — Small footprint and controlled leakage current are useful for local decoupling and transient suppression in sensor interfaces and control boards.

Unique Advantages

• Space-efficient package: The φ5 × 11 mm can and radial lead form provide a compact footprint for dense PCB layouts.
• Designed for switching environments: Low tan δ and defined ripple current ratings at both low and high frequencies align with filtering needs in switching supplies.
• Extended temperature operation: Rated for –55°C to +105°C with a 2000-hour endurance at 105°C for consistent performance in elevated-temperature applications.
• Automotive-capable qualification: AEC‑Q200 rating in the product data supports selection where qualified passive components are required.
• Through-hole mounting simplicity: Radial lead format and standard 2 mm lead spacing simplify assembly and mechanical retention in through-hole designs.
• Measured leakage and tolerance: Specified leakage current (22.68 µA) and ±20% capacitance tolerance aid predictable circuit behavior and BOM control.
