UPW2F101MHD

The UPW2F101MHD is a polarized aluminum electrolytic capacitor from Nichicon's UPW series designed for compact, high-reliability power applications. It is a radial-lead, can-style capacitor optimized for switching power supplies and automotive electronics where low impedance and sustained ripple handling are required.

This part delivers a 100 µF capacitance at a rated voltage of 315 V in a compact package (L: 4 × D: 1.8 cm) with radial lead mounting. It combines high-temperature endurance and AEC-Q200 qualification to meet demanding operational and reliability requirements.

Key Features

• Capacitance & Rated Voltage — 100 µF capacitance at 315 V, suitable for bulk and filtering roles in high-voltage power rails.
• Low Impedance Design — Rated ripple current of 285 mA at 120 Hz and 456 mA at 10 kHz supports effective AC ripple smoothing in switching supplies.
• High-Temperature Endurance — Operates from −40°C to 105°C with a specified lifetime of 8000 hours at 105°C, supporting long-term stability in elevated-temperature environments.
• AEC-Q200 Qualification — Automotive-oriented reliability rating for use in vehicle electronics and other applications requiring industry-recognized stress screening.
• Compact Radial Package — Radial, can-style construction with 7.5 mm lead spacing and polarized configuration for straightforward through-hole mounting and robust mechanical retention.
• Capacitance Tolerance — Specified tolerance of −20% to +20% for predictable sizing in design margin calculations.
• Leakage Current Characteristic — Series specification: after 1 minute’s application of rated voltage at 20°C, leakage current is not more than 0.03CV (µA), supporting low-standby losses.

Typical Applications

• Automotive Power Electronics — Energy storage and filtering in vehicle power modules and DC-DC converters, leveraging AEC-Q200 qualification and 105°C endurance.
• Switching Power Supplies — Input/output smoothing and bulk decoupling for high-voltage switching regulators where low impedance and sustained ripple capability are required.
• High-Voltage DC Systems — Bulk capacitance and ripple suppression on high-voltage rails up to the 315 V rating.

Unique Advantages

• AEC-Q200-rated reliability — Meets automotive stress screening expectations, easing qualification in safety- and reliability-sensitive designs.
• Long life at elevated temperature — 8000 hours at 105°C supports extended field life in thermally challenging environments.
• Designed for ripple performance — Specified ripple current at both low and high frequencies (120 Hz and 10 kHz) enables effective filtering across switch-mode converter spectra.
• Compact, serviceable form factor — Radial lead can and 7.5 mm lead spacing simplify through-hole assembly and replacement in serviceable equipment.
• Predictable electrical behavior — Defined leakage current and ±20% capacitance tolerance support accurate power-supply design and margining.
