RF80E101MDN1

The RF80E101MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a low-profile radial can (φ5×8 mm) optimized for general-purpose electronics. It delivers low ESR/ESL and high ripple-current capability in a compact, polarized radial-lead package suited to board-level power and decoupling needs.

Designed for reliability under elevated temperatures, this part offers a 2.5 V rated voltage, 100 µF capacitance, and a load life of 2000 hours at 105°C, while meeting RoHS requirements.

Key Features

• Low ESR/ESL — ESR 7 mΩ measured at 100 kHz (20°C) and typical ESL around 1.5 nH, supporting stable performance at high switching frequencies.
• High ripple-current capability — Rated ripple current 4,200 mA (4.2 A) with frequency behavior that maintains full coefficient at high frequencies (300 kHz), enabling robust handling of switching ripple.
• Compact, low-profile package — Case size φ5×8 mm with 2.0 mm lead spacing and radial lead mounting for space-constrained board layouts.
• Thermal endurance — Load life of 2000 hours at 105°C; operating temperature range −55°C to +105°C.
• Electrical rating and tolerance — 100 µF nominal capacitance at 2.5 V with ±20% tolerance (at 120 Hz, 20°C).
• Radial lead, lead-free solder compatible — Radial lead type with lead-free flow soldering condition correspondence for assembly processes.
• RoHS compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electronics — Provides low ESR and high ripple handling for board-level decoupling and bulk capacitance in a variety of electronic products.
• High-frequency switching environments — Handles high ripple currents at hundreds of kilohertz, supporting switching regulator and converter circuits that require stable filtering.
• Compact, space-constrained designs — Small φ5×8 mm can and 2.0 mm lead spacing make it suitable where low profile and tight layout are important.

Unique Advantages

• Measurable low ESR — 7 mΩ at 100 kHz minimizes series losses and helps control output ripple in high-frequency circuits.
• High-frequency ripple endurance — 4.2 A ripple rating (at 300 kHz coefficient = 1.00) supports modern switching topologies without compromising lifetime.
• Long-term thermal reliability — 2000 hours at 105°C load life provides confidence for extended operation in elevated-temperature environments.
• Compact footprint — φ5×8 mm package and 2.0 mm lead spacing allow dense PCB placement while preserving performance.
• Assembly-friendly radial leads — Radial-lead format with lead-free flow solder compatibility simplifies through-hole assembly processes.
• Regulatory compliance — RoHS conformity enables use in regulated production environments.
