UPS2E101MRD6

The UPS2E101MRD6 from Nichicon is a miniature, low‑impedance aluminum electrolytic capacitor in the UPS series, designed for radial‑lead mounting. It provides 100 µF capacitance at a 250 V rating and is intended for general‑purpose applications including switching power supplies.

Key practical attributes include radial can packaging with 1 cm lead spacing, an operating temperature range that supports up to 105°C, RoHS compliance, and rated ripple current performance across low and high frequencies—benefits important for power‑rail smoothing and energy buffering in compact designs.

Key Features

• Capacitance & Voltage — 100 µF capacitance with a 250 V rated voltage and ±20% tolerance, suitable for bulk energy storage and smoothing on higher‑voltage rails.
• Low Impedance / Ripple Handling — Specified ripple current: 340 mA at 120 Hz and 544 mA at 10 kHz, supporting switching power supply ripple suppression across common frequencies.
• Compact Radial Package — Radial, can style package with 1 cm lead spacing and physical size L: 3.1 × D: 2 cm, allowing for straightforward through‑hole mounting and placement in space‑constrained assemblies.
• Wide Operating Temperature — Rated for operation from −40°C to 105°C, enabling use across a broad range of ambient conditions.
• High‑Temperature Endurance — Designed for 3000 hours of life at 105°C, providing predictable long‑term performance under elevated temperature stress.
• Compliance — RoHS directive compliant (2011/65/EU, (EU)2015/863), meeting common environmental regulatory requirements.
• Polarized Design — Polarized electrolytic capacitor for conventional DC filtering and energy storage applications.

Typical Applications

• Switching Power Supplies — Output filtering and energy buffering to reduce voltage ripple and stabilize power rails in switching regulators and converters.
• General Purpose Power Smoothing — Bulk decoupling and hold‑up capacitance in consumer and industrial power supply circuits.
• Power Rail Support in Embedded Systems — Local energy storage for high‑voltage DC rails where a compact radial can capacitor is required.

Unique Advantages

• Compact footprint for through‑hole designs — The 3.1 × 2 cm package and radial lead format simplify mechanical integration on crowded PCBs or multi‑layer assemblies.
• High voltage capability — 250 V rating enables use on higher DC bus voltages without series stacking or paralleling.
• Measured ripple performance — Specified ripple currents at both 120 Hz and 10 kHz support effective filtering across switching and line frequencies.
• Durable at elevated temperatures — 3000‑hour endurance at 105°C provides predictable aging characteristics for designs exposed to sustained heat.
• Environmentally compliant — RoHS compatibility helps meet regulatory and corporate environmental requirements.
