UHE2A270MPD

The UHE2A270MPD is a radial-lead aluminum electrolytic capacitor offering 27 µF capacitance at a 100 V rated voltage in a compact φ8 × 11.5 mm can. It is part of Nichicon’s UHE series, characterized in the datasheet as miniature sized with low impedance and high reliability.

Designed for general-purpose electronic designs, this polarized radial capacitor provides defined ripple-current performance, low leakage, and long-term endurance up to 7000 hours at 105°C, making it suitable for through-hole applications that require stable capacitance and predictable lifetime.

Key Features

• Capacitance & Voltage — 27 µF nominal capacitance with ±20% tolerance, rated for 100 V DC operation.
• Low Loss — tanδ (loss tangent) specified at 0.08 measured at 20°C, 120 Hz for the 100 V rating.
• Low Impedance — impedance specified as 2.8 Ω to support low-impedance circuit requirements.
• Ripple Current Capability — rated ripple current of 143 mA at 120 Hz (low frequency) and 260 mA at 10 kHz (high frequency), with frequency coefficients provided in the series data.
• Long Endurance & Wide Temperature Range — rated for 7000 hours at 105°C (for 16–100 V, φD = 8) and an operating temperature range of –40°C to +105°C.
• Compact Radial Package — φ8 × 11.5 mm can, radial lead mounting with 3.5 mm lead spacing (±0.5 mm), available in bulk or bag packing.
• Low Leakage — leakage current specified at 27 µA (after 2 minutes’ application of rated voltage, per series guidance).
• Environmental Compliance — RoHS compliant.

Typical Applications

• General Purpose Electronics — Provides 27 µF/100 V capacitance for polarized-capacitor needs in a variety of general-purpose circuits.
• High-Temperature Systems — Suitable for designs operating between –40°C and 105°C with a specified 7000-hour endurance at 105°C for the 16–100 V range.
• Through-Hole Radial Designs — Compact φ8 can and 3.5 mm lead spacing simplify integration into radial-lead assemblies and PCB layouts.

Unique Advantages

• High-voltage capacitance in a small footprint: 27 µF at 100 V in a φ8 × 11.5 mm can helps save board space in through-hole designs.
• Low loss and defined impedance: tanδ of 0.08 (20°C, 120 Hz) combined with 2.8 Ω impedance supports designs that require predictable AC behavior.
• Frequency-aware ripple performance: Rated ripple currents of 143 mA (120 Hz) and 260 mA (10 kHz) provide clear guidance for ripple-handling in different frequency ranges.
• Predictable long-term reliability: 7000-hour endurance at 105°C for the 16–100 V range offers a documented lifetime for thermal-stress conditions.
• Low leakage for steady-state applications: 27 µA leakage current helps maintain charge retention and limits standby losses where leakage matters.
• RoHS-compliant packaging options: Available in bulk or bag packing to support flexible procurement and assembly workflows.
