UPJ1V221MPD

The UPJ1V221MPD from Nichicon is a radial lead aluminum electrolytic capacitor in the UPJ series designed for low impedance performance. This 220 µF, 35 V polarized capacitor is optimized for power applications that require reliable ripple handling and compact radial packaging.

Targeted at general-purpose and power supply applications, the UPJ1V221MPD delivers measurable ripple current capability, extended operating temperature range, and a 3000-hour endurance rating at 105°C for the φ8 case size.

Key Features

• Capacitance & Tolerance — 220 µF nominal with ±20% tolerance (−20% to +20%) for predictable bulk energy storage and filtering.
• Rated Voltage — 35 V DC rating suitable for mid-voltage power rails and decoupling in power supply circuits.
• Low Impedance Design — Part of Nichicon’s UPJ low-impedance series, making it suitable for switching power supply applications where lower impedance improves transient and ripple performance.
• Ripple Current Capability — Low-frequency ripple current of 324.8 mA at 120 Hz and high-frequency ripple current of 580 mA at 200 kHz to support input/output filtering in regulated supplies.
• Leakage Current — Specified leakage current of 231 µA aids in predictable retention and minimal standby losses after 1 minute at rated voltage (20°C).
• Temperature & Endurance — Operating temperature range −55°C to +105°C with a rated lifetime of 3000 hours at 105°C for the φ8 case size.
• Compact Radial Package — φ8 × 20 mm can with 3.5 mm lead spacing (±0.5 mm) for through-hole assembly and flexible board placement; available in bulk or bag packing.
• RoHS Compliant — Meets RoHS requirements for use in lead-restricted assemblies.

Typical Applications

• Switching Power Supplies — Low-impedance UPJ series construction and specified ripple currents make this capacitor well suited for input/output filtering and decoupling in DC-DC converters and switch-mode power supplies.
• General-Purpose Power Filtering — 220 µF capacitance and 35 V rating provide bulk smoothing and transient suppression on mid-voltage rails across embedded and electronic control boards.
• Space-Constrained Through-Hole Designs — Compact φ8×20 mm radial can and 3.5 mm lead spacing enable placement in dense assemblies where a small footprint and through-hole reliability are required.

Unique Advantages

• Designed for switching applications — Series-level low-impedance design plus measured ripple current specs support stable operation in switching power topologies.
• High-frequency ripple performance — 580 mA at 200 kHz helps reduce voltage ripple and improve regulator stability in high-frequency converters.
• Extended operating range — −55°C to +105°C rating supports a wide range of environmental conditions for reliable field performance.
• Long-life capability for small case sizes — 3000-hour endurance at 105°C for the φ8 case size provides predictable aging characteristics for maintenance and life-cycle planning.
• Compact, through-hole form factor — Radial can with 3.5 mm lead spacing simplifies board layout for designers preferring through-hole components.
• Regulatory compliance — RoHS compliance aligns with lead-restricted manufacturing and regulatory requirements.
