UPJ1K221MHD6

The UPJ1K221MHD6 is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPJ series. It is a radial-lead, polarized can-type capacitor with a 220 µF capacitance and an 80 V rated voltage, designed for board-level power applications.

Built for general-purpose power filtering and low-impedance performance, this part is well suited to switching power supplies and other power-management circuits that require long life and stable behavior across a wide temperature range.

Key Features

• Capacitance & Voltage: 220 µF capacitance with an 80 V rated voltage, suitable for higher-voltage power applications.
• Low-loss performance: tanδ (DF) = 0.08 measured at 20°C, 120 Hz, providing reduced dissipation at rated conditions.
• High ripple capability: Low-frequency ripple current 360.08 mA at 120 Hz and high-frequency ripple current 643 mA at 200 kHz to support power-supply smoothing and decoupling.
• Leakage current: Specified leakage current of 528 µA for predictable quiescent current behavior.
• Long endurance: Rated for 5000 hours life at 105°C, delivering extended service life in elevated-temperature environments.
• Temperature range: Operates from −55°C to +105°C for broad environmental compatibility.
• Compact radial package: Can dimension φ18 × 15 mm length with 7.5 mm lead spacing (±0.5 mm), radial lead mounting for through-hole assemblies.
• Packaging options: Supplied in bulk (no terminal forming) or bag packing for flexible handling and assembly processes.
• Compliance: RoHS-compliant construction.

Typical Applications

• Switching Power Supplies: Low-impedance characteristics and high ripple capability make it suitable for input/output smoothing and energy storage in switching regulators.
• Power Filtering in Industrial Electronics: 80 V rating and 220 µF capacitance support bulk filtering and decoupling in higher-voltage industrial power rails.
• General-Purpose Board-Level Power: Radial-lead format and compact φ18×15 mm size fit through-hole designs where reliable, long-life capacitance is required.

Unique Advantages

• Designed for long-term high-temperature operation: 5000 h endurance at 105°C reduces maintenance and replacement frequency in hot environments.
• Measurable low dissipation: tanδ = 0.08 at 20°C/120 Hz indicates controlled dielectric losses for stable performance under AC excitation.
• Dual-frequency ripple capability: Specified ripple currents at 120 Hz and 200 kHz cover both low- and high-frequency power components encountered in modern supplies.
• Robust leakage specification: Defined leakage current (528 µA) supports predictable standby and quiescent behavior in power systems.
• Compact through-hole format: φ18 × 15 mm can with 7.5 mm lead spacing provides a space-efficient option for radial-mount designs while maintaining serviceability.
• RoHS compliant: Meets environmental directive requirements for lead-free assembly processes.
