UPJ1H221MPD

The UPJ1H221MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPJ series, designed for low impedance and long-life operation. It delivers 220 µF capacitance at a 50 V rating with polarized radial mounting in a compact φ10×25 mm can.

Engineered for power applications, this capacitor is ideally suited for switching power supplies and general-purpose circuits that require stable capacitance, high ripple handling and extended endurance up to 105°C.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a rated voltage of 50 V and a tolerance of −20% to +20% at 20°C, 120 Hz.
• Low Loss (tan δ) — tanδ = 0.10 specified at 20°C, 120 Hz, 50 V for controlled dissipation factor in power circuits.
• High Ripple Capability — Low-frequency ripple current 425.6 mA (120 Hz) and high-frequency ripple current 760 mA (1 kHz) for demanding supply decoupling.
• Leakage Current — Specified leakage current of 330 µA after rated voltage application, providing predictable leakage behavior for power designs.
• Long Endurance — Rated for 5000 hours at +105°C (life/endurance condition), supporting sustained operation in elevated-temperature environments.
• Wide Temperature Range — Operates from −55°C to +105°C to accommodate a broad set of environmental conditions.
• Package & Mounting — Radial lead can, size φ10×25 mm (D: 10 mm × L: 25 mm) with 5 mm lead spacing (±0.5 mm). Available in bulk or bag packing.
• Regulatory Compliance — RoHS compliant as specified in product information.

Typical Applications

• Switching Power Supplies — Intended for use in switching power supply designs where low impedance and reliable ripple handling are important.
• General-Purpose Circuits — Suitable for general-purpose polarized capacitor requirements in electronic products that need energy storage and decoupling.
• Power Filtering and Smoothing — Used for bulk smoothing and filter stages where 220 µF at 50 V and the specified ripple currents meet circuit needs.

Unique Advantages

• Low-Impedance Design: The UPJ series construction delivers low impedance characteristics that improve voltage stability under ripple and transient conditions.
• High Ripple Endurance: Defined low- and high-frequency ripple current ratings (425.6 mA at 120 Hz, 760 mA at 1 kHz) enable reliable handling of AC stress in power rails.
• Extended High-Temperature Life: Rated for 5000 hours at +105°C, providing predictable long-term performance in elevated-temperature environments.
• Compact Radial Can: φ10×25 mm form factor with 5 mm lead spacing offers a space-efficient solution for through-hole layouts.
• Controlled Electrical Characteristics: Specified tanδ (0.10 at 20°C, 120 Hz) and defined leakage current (330 µA) aid in predictable circuit behavior and design margining.
• RoHS Compliance: Meets RoHS requirements, simplifying regulatory considerations for many designs.
