RS81C101MCNASQ

The RS81C101MCNASQ is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead, low-profile can (φ6.3×8 mm). Engineered for general-purpose electronic designs, it delivers low ESR/ESL and high ripple-current capability in a compact package.

Key attributes include a 100 µF capacitance at 16 V, a wide operating temperature range from –55 °C to 105 °C, and a rated load life of 5000 hours at 105 °C, making it suitable for applications that require stable capacitance and robust ripple handling in tight board spaces.

Key Features

• Conductive polymer aluminum solid electrolytic construction — Provides low ESR and low ESL characteristics for improved high-frequency performance.
• Capacitance and voltage — 100 µF capacitance rated at 16 V with ±20% tolerance at 120 Hz, 20 °C.
• Low ESR — ESR of 14 mΩ measured at 20 °C / 100 kHz, supporting reduced impedance at high frequencies.
• High ripple current capability — Rated ripple current 380 mA at 120 Hz (low frequency) and 3.8 A at 300 kHz (high frequency), with frequency coefficients specified across common bands.
• Leakage and dissipation — Leakage current specified at 500 µA and tan δ (DF) of 0.1 measured at 20 °C, 120 Hz.
• Thermal and endurance characteristics — Operating temperature range of –55 °C to 105 °C and endurance of 5000 hours at 105 °C under rated voltage.
• Compact radial package — Dimension φ6.3 × 8 mm with 2.5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole designs; available in bulk/bag packing.
• RoHS compliant — Conforms to current RoHS requirements.

Typical Applications

• Power supply filtering and decoupling — Low ESR and high ripple-current capability support smoothing and decoupling in compact power modules and regulators.
• DC–DC converter output caps — Compact radial package and stable performance at high frequency make it suitable for converter output filtering where board space is limited.
• General-purpose electronics — Suitable for a wide range of consumer and industrial circuits that require reliable, low-impedance capacitance in through-hole form factors.

Unique Advantages

• Low impedance at high frequency: 14 mΩ ESR at 100 kHz reduces voltage ripple and improves transient response in high-frequency circuits.
• High ripple handling: Rated ripple currents of 380 mA (120 Hz) and 3.8 A (300 kHz) allow the capacitor to support demanding ripple environments.
• Wide temperature and long life: –55 °C to 105 °C operating range with 5000 hours endurance at 105 °C provides consistent performance in elevated-temperature applications.
• Space-efficient radial can: φ6.3 × 8 mm footprint with 2.5 mm lead spacing offers a compact through-hole solution for dense PCB layouts.
• Stable dissipation characteristics: tan δ of 0.1 (20 °C, 120 Hz) and defined leakage current improve predictability in designs requiring controlled dielectric loss and leakage.
• RoHS compliance: Meets environmental regulatory requirements for lead-free designs.
