UPW1J221MPD

The UPW1J221MPD is a 220 µF, 63 V aluminum electrolytic capacitor from Nichicon's UPW series, optimized for miniature, low-impedance power designs. It is a radial‑lead, polarized can designed for use in switching power supplies and automotive electronic systems.

Key value propositions include a compact package (L: 2 × D: 1 cm), low impedance (294 mΩ), high-frequency ripple capability, and long-term endurance at elevated temperature (5,000 hours at 105°C), making it suitable where size, ripple performance, and reliability matter.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance at a rated voltage of 63 V with ±20% tolerance for bulk energy storage and decoupling in power rails.
• Low Impedance — Rated impedance of 294 mΩ to reduce voltage ripple and improve dynamic response in switching regulators.
• High-Frequency Ripple Handling — Specified ripple current of 885 mA at 10 kHz and 575.3 mA at 120 Hz for effective handling of switching noise across typical converter frequencies.
• Compact Radial Can Package — Radial lead, polarized can with 5 mm lead spacing for through-hole assembly in space-constrained layouts.
• Wide Operating Temperature — Specified for −55°C to +105°C for use across harsh thermal environments.
• Automotive-Grade Reliability — AEC‑Q200 rating and a 5,000-hour lifetime at 105°C, supporting long-term reliability requirements in automotive electronics.

Typical Applications

• Switching Power Supplies — Bulk and output capacitance for switch-mode power supplies where compact, low-impedance filtering is required.
• Automotive Electronic Subsystems — Energy storage and ripple mitigation in automotive ECUs and power modules, supported by AEC‑Q200 qualification.
• High-Frequency Power Stages — Circuits requiring reliable ripple handling up to 10 kHz, leveraging the capacitor's specified high-frequency ripple current.

Unique Advantages

• Miniature footprint with substantive capacitance: 220 µF in a 2 × 1 cm package enables dense board layouts without sacrificing energy storage.
• Low-impedance performance: 294 mΩ impedance reduces ESR-related losses and improves voltage stability under load.
• High ripple capacity across frequencies: Explicit ripple ratings at 120 Hz and 10 kHz let designers quantify thermal and ripple handling in both line-frequency and switching-frequency domains.
• Elevated-temperature endurance: 5,000 hours at 105°C provides a measurable reliability baseline for high-temperature system designs.
• Automotive qualification: AEC‑Q200 rating indicates suitability for automotive-grade applications where that qualification is required.
• Robust operating range: −55°C to +105°C supports a broad set of environmental conditions.
