PLX1E121MDL1

The PLX1E121MDL1 is a radial-lead conductive polymer aluminum solid electrolytic capacitor from Nichicon’s PLX series. It delivers low ESR and high ripple-current capability in a compact radial can footprint designed for demanding temperature and reliability requirements.

Targeted for automotive and other high-reliability markets, this polarized capacitor offers long-life performance with a rated capacitance of 120 µF at 25 V and an operating range of −55 °C to +125 °C.

Key Features

• Capacitance & Voltage — 120 µF nominal capacitance rated at 25 V with ±20% tolerance at 120 Hz, 20 °C.
• Conductive-Polymer Construction — Solid electrolyte design providing low impedance and stable performance across temperature.
• Low ESR — 27 mΩ equivalent series resistance measured at 100 kHz, supporting lower loss and improved efficiency in power circuits.
• High Ripple Current — 445 mA at 120 Hz and 890 mA at 100 kHz, enabling effective smoothing and decoupling in high-frequency and power applications.
• Long Life at Elevated Temperature — Endurance rated to 3000 hours at 125 °C with specified limits for capacitance change, tan δ, and ESR.
• Wide Temperature Range — Specified for operation from −55 °C to +125 °C, with impedance stability (Z(+125 °C)/Z(+20 °C) ≤ 1.25 at 100 kHz).
• Radial Lead Package — Radial can with 3.5 mm lead spacing and lead-free flow soldering condition correspondence for through-hole mounting.
• Quality & Compliance — AEC-Q200 qualified and RoHS compliant.

Typical Applications

• Automotive Power Electronics — Bulk decoupling and smoothing on 12 V/24 V power rails and control modules where high ripple tolerance and temperature endurance are required.
• ECU and Control Modules — Local energy storage and transient suppression in engine, transmission, and vehicle control units benefiting from long-life ratings and AEC-Q200 qualification.
• Sensor and Actuator Interfaces — Stabilizing power to precision sensors and actuators operating across wide temperature ranges.

Unique Advantages

• Low-loss performance: 27 mΩ ESR at 100 kHz reduces dissipation and supports efficient power handling in compact designs.
• High-frequency capability: Measured ripple current at 100 kHz (890 mA) makes the part suitable for switching power supplies and high-speed decoupling.
• Temperature endurance: Rated for 3000 hours at 125 °C, providing predictable aging and reliability in elevated-temperature environments.
• Automotive-qualified: AEC-Q200 qualification supports use in automotive applications that demand component-level qualification.
• Compact radial package: Small can footprint (L: 1.2 × D: 0.8 cm) with 3.5 mm lead spacing simplifies through-hole placement while maintaining performance.
• Regulatory compliance: RoHS conformity and lead-free flow soldering correspondence ease integration into compliant manufacturing processes.
