UPJ1E221MPD

The UPJ1E221MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's UPJ series, designed for low-impedance, high-reliability power applications. Its compact φ8 × 15 mm can and radial lead form factor make it suitable for space‑constrained power filtering and decoupling tasks.

Engineered for switching power supplies and general-purpose power rails, this 220 µF, 25 V polarized capacitor provides defined ripple handling, a wide operating temperature range, and long endurance for demanding electronic designs.

Key Features

• Electrical Performance — 220 µF capacitance at 25 V rated voltage with ±20% tolerance, suitable for bulk filtering and decoupling on DC power rails.
• Low Loss / Low Impedance — tanδ (DF) 0.14 measured at 20°C, 120 Hz, indicating reduced AC loss for improved filtering efficiency.
• Ripple Current Handling — Low-frequency ripple current 254.8 mA (120 Hz) and high-frequency ripple current 455 mA (200 kHz) to support both line-frequency and switching-frequency ripple demands.
• Leakage Current — Specified leakage current of 165 µA, enabling predictable standby and idle-current behavior in power designs.
• High Reliability / Endurance — Rated for 3000 hours endurance at 105°C (φ8 case), supporting long-term operation at elevated temperatures.
• Mechanical / Mounting — Radial lead, can-style package with 3.5 mm lead spacing (±0.5 mm) for through‑hole board assembly and secure mechanical retention.
• Operating Range & Compliance — Wide temperature range of -55°C to +105°C; RoHS compliant.
• Packaging — Available in bulk (no terminal forming) and bag packing to suit production handling and assembly workflows.

Typical Applications

• Switching Power Supplies — Bulk and output filtering where low impedance and defined ripple handling improve voltage stability and transient response.
• DC-DC Converters — Input/output decoupling and energy buffering in compact converter modules requiring radial-lead components.
• Industrial Power Electronics — Filtering and smoothing on control boards and power distribution circuits operating across -55°C to +105°C.
• Consumer and Embedded Devices — General-purpose power-rail decoupling in space‑constrained assemblies that benefit from a small φ8 can and radial mounting.

Unique Advantages

• Low-impedance behavior at key frequencies — Measured tanδ and specified ripple currents support efficient filtering at both 120 Hz and 200 kHz.
• Defined leakage current — 165 µA leakage provides predictable idle current for power budgeting and system-level energy calculations.
• Compact, board-friendly form factor — φ8 × 15 mm can with 3.5 mm lead spacing delivers a small footprint while retaining robust through-hole mounting.
• Long endurance at elevated temperature — 3000 hours at 105°C (φ8) supports sustained operation in hotter environments.
• Wide operating temperature — −55°C to +105°C enables use across a broad range of environmental conditions.
• RoHS compliant — Conforms to RoHS requirements for materials compliance in regulated product assemblies.
