The UCY2E270MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UCY series. It is a radial-lead, polarized capacitor specified at 27 µF and 250 V, designed for power filtering and energy smoothing in demanding environments.

Built for applications that require sustained ripple handling and long service life, this part delivers high ripple current capability, a wide temperature range of −40 °C to +105 °C, and 10,000 hours of endurance at 105 °C.

Key Features

• Capacitance & Voltage — 27 µF nominal capacitance with a rated voltage of 250 V and tolerance of −20% to +20%.
• High Ripple Current — Designed for heavy ripple applications with 255 mA at 120 Hz (low frequency) and 510 mA at 100 kHz (high frequency).
• Long Life & Endurance — Load-life endurance of 10,000 hours at +105 °C, suitable for prolonged high-temperature operation.
• Low Dielectric Loss — Tan δ (loss tangent) of 0.20 measured at 20 °C, 120 Hz, supporting efficient energy handling.
• Leakage Current — Specified leakage current of 370 µA, measured under rated conditions.
• Compact Radial Package — φ10 × 20 mm can with 5.0 mm lead spacing (lead spacing tolerance ±0.5 mm), radial-lead mounting for through-hole designs.
• Automotive-Grade Qualification — AEC-Q200 rated and intended for applications requiring automotive-grade reliability.
• RoHS Compliant & Packaging — RoHS-compliant construction with bulk (no terminal forming) or bag packaging; part is in mass production.

Typical Applications

• Power Supplies — Bulk filtering and smoothing on DC power rails where sustained ripple current and stability over temperature are required.
• Ballasts & Lighting Electronics — Energy smoothing and ripple handling in ballast circuits and lamp drivers.
• Automotive Electronic Modules — Power decoupling and stabilization in automotive systems that benefit from AEC-Q200 qualification and extended high-temperature life.
• Industrial Control Power Rails — Filtering and energy storage in industrial power supplies and control electronics exposed to elevated temperatures.

Unique Advantages

• High ripple capacity: Enables reliable operation in circuits with significant AC ripple currents, minimizing voltage fluctuation under load.
• Long, high-temperature life: 10,000 hours at 105 °C provides predictable longevity for designs deployed in warm environments.
