PCF1D121MCL1GS

The PCF1D121MCL1GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount, radial can package. It delivers low ESR and high ripple-current capability in a compact φ10 × 10 mm case for designs requiring robust power-decoupling components.

Designed for automotive applications and AEC-Q200 qualification, this capacitor offers a wide operating temperature range and extended endurance for demanding environments where stable capacitance and low loss are required.

Key Features

• Capacitance and Voltage: 120 µF rated at 20 V with capacitance tolerance of −20% to +20% (±20% at 120 Hz, 20°C).
• Low ESR & High Ripple Handling: ESR of 35 mΩ measured at 20°C/100 kHz, with low-frequency ripple current 1.4 A (120 Hz) and high-frequency ripple current 2.8 A (100 kHz).
• Dielectric and Loss: Conductive polymer aluminum solid electrolyte with tan δ (DF) of 0.12 measured at 20°C, 120 Hz, 20 V.
• Reliability & Endurance: Load life of 2000 hours at 105°C; leakage current specified at 480 µA (after standard conditioning).
• Temperature Range: Rated for −55°C to +105°C operation.
• Packaging & Mounting: Surface-mount radial can (φ10 × 10 L) supplied in embossed carrier taping with moisture-proof packing; compatible with lead-free reflow soldering (260°C peak correspondence per series datasheet).
• Compliance & Qualification: AEC-Q200 qualified and RoHS compliant.

Typical Applications

• Automotive Electronics — provides low ESR and high ripple-current support for power decoupling and smoothing in automotive control modules and electronic systems.
• Power Conversion Stages — suits DC–DC converter outputs and switching power stages where 1.4 A (120 Hz) and 2.8 A (100 kHz) ripple handling reduces voltage ripple and improves stability.
• High-Temperature, Long-Life Systems — the 2000‑hour endurance at 105°C and −55°C to +105°C temperature range support in-vehicle and other harsh-environment electronics.

Unique Advantages

• High ripple-current capacity: Enables smaller capacitor arrays or fewer parallel devices thanks to 1.4 A (120 Hz) and 2.8 A (100 kHz) ripple ratings tied to the device’s low ESR.
• Low equivalent series resistance: 35 mΩ ESR at 100 kHz keeps losses and heat generation low in high-frequency power applications.
• Automotive-grade reliability: AEC-Q200 qualification plus a 2000‑hour life at 105°C give design confidence for automotive and other mission-critical deployments.
• Compact SMD can format: φ10 × 10 mm package provides a high-capacitance, high-performance option in a compact surface-mount footprint with embossed carrier taping for automated assembly.
• Stable electrical characteristics: Specified tan δ (0.12) and controlled leakage current (480 µA) support predictable behavior across temperature and frequency conditions.
