RS81C101MDNASQ

The RS81C101MDNASQ is a Nichicon RS8 series conductive polymer aluminum solid electrolytic capacitor designed for general-purpose power applications. It combines a low-profile φ6.3×8 mm radial-can package with low ESR/ESL construction and high ripple-current capability.

Key advantages include compact size, robust ripple handling and low equivalent series resistance—attributes that support power smoothing and decoupling in compact electronic designs across industrial and consumer segments. The part is lead-free flow soldering condition compatible and RoHS compliant.

Key Features

• Dielectric / Electrolyte: Conductive polymer aluminum solid electrolytic construction for stable electrical performance.
• Low ESR / ESL: ESR = 14 mΩ at 100 kHz (20°C), supporting low-loss power delivery and improved transient response.
• High Ripple Current: Rated ripple current 380 mA at 120 Hz and 3.8 A at 300 kHz, enabling effective handling of both low- and high-frequency ripple.
• Compact, Low-Profile Package: Case size φ6.3×8 mm (L: 8 × D: 6.3 mm) with 2.5 mm lead spacing in a radial lead can for space-constrained layouts.
• Electrical Ratings: 100 µF nominal capacitance at 16 V rated voltage with ±20% tolerance; polarized device for correct polarity applications.
• Temperature & Reliability: Operating temperature range –55°C to +105°C and rated lifetime of 5000 hours at 105°C.
• Compliance & Assembly: Radial lead type with lead-free flow soldering condition correspondence and RoHS directive compliance.

Typical Applications

• Power supply decoupling: Low ESR and high ripple capability make this capacitor suitable for smoothing and decoupling in compact power rails.
• Point-of-load filtering: High-frequency ripple current rating (3.8 A at 300 kHz) supports filtering in switching regulator outputs and DC‑DC converters.
• Space-constrained electronics: Low-profile φ6.3×8 mm package and radial lead form factor fit compact boards where vertical clearance is limited.
• General-purpose industrial and consumer circuits: Broad temperature range (–55°C to +105°C) and RoHS compliance enable use across a variety of general-purpose designs.

Unique Advantages

• Improved power-handling capability: High ripple current ratings at both low and high frequencies reduce heating and support robust operation under switching loads.
• Low-loss performance: 14 mΩ ESR at 100 kHz minimizes energy dissipation and contributes to stable voltage regulation and transient response.
• Compact footprint: φ6.3×8 mm low-profile can conserves board area and vertical space without sacrificing ripple performance.
• Designed for long-term reliability: Rated for 5000 hours at 105°C, providing predictable endurance in elevated-temperature applications.
• Assembly-friendly: Radial lead configuration with lead-free flow soldering condition correspondence simplifies through-hole mounting and wave/flow processes.
• Regulatory compliance: Conforms to RoHS (2011/65/EU, (EU)2015/863) for restricted substances compliance in regulated markets.
