PLX1D271MDL1

The PLX1D271MDL1 is a radial-lead conductive polymer aluminum solid electrolytic capacitor offering 270 µF capacitance at a 20 V rating. It combines low impedance and high ripple-current capability with a long rated life for demanding power-electronics environments.

Targeted for automotive and other high-reliability power applications, this part delivers measurable performance in high-temperature and high-frequency conditions while supporting through-hole assembly with radial leads.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance rated at 20 V, with ±20% tolerance at 120 Hz, 20°C.
• Low ESR & High-Frequency Performance — ESR of 24 mΩ measured at 20°C/100 kHz, enabling reduced impedance at high frequency.
• Ripple Current Capability — Low-frequency ripple current 555 mA (120 Hz) and high-frequency ripple current 1.11 A (100 kHz) to support high-stress power circuits.
• Long Life & Wide Temperature Range — Rated for 3000 hours at 125°C and an operating range of –55°C to +125°C for sustained high-temperature operation.
• Leakage & Loss — Leakage current specified at 1080 µA; loss tangent (tan δ) 0.12 measured at 20°C, 120 Hz.
• Package & Mounting — Radial can package, size φ10 × 13 mm length, lead spacing 5.0 mm (±0.5 mm), supplied bulk or in bags for through-hole assembly.
• AEC-Q200 Qualified — Designed to meet AEC-Q200 qualification requirements for demanding electronic applications.
• RoHS Compliant — Conforms to RoHS directives for restricted substances.

Typical Applications

• Automotive power electronics — Used for smoothing and decoupling in systems that require high ripple-current handling and elevated operating temperature endurance.
• DC–DC converters — Provides low impedance at switching frequencies to reduce output voltage ripple and improve regulation stability.
• Power modules and control units — Suitable for local energy storage and transient suppression where long life at high temperature is required.

Unique Advantages

• Measurable low impedance: 24 mΩ ESR at 100 kHz translates directly to lower voltage drop under high-frequency load, improving power delivery at the board level.
• High ripple tolerance: Specified ripple currents (555 mA @120 Hz, 1.11 A @100 kHz) allow designers to select this capacitor for circuits with significant AC stress.
• Extended high-temperature lifetime: 3000 hours at 125°C provides predictable end-of-life behavior for thermal-stressed designs.
• Through-hole reliability: Radial lead, can-style package and compatibility with lead-free flow soldering simplify integration into mixed-technology assemblies.
• Automotive-grade qualification: AEC-Q200 rating supports use in qualified electronic systems where that qualification is required.
