PCF1A121MCL1GS

The PCF1A121MCL1GS is a conductive polymer aluminum solid electrolytic capacitor in a compact surface-mount can package. Designed for demanding temperature and ripple environments, it delivers low equivalent series resistance (ESR) and high ripple current capability for robust power-conditioning in automotive and industrial electronics.

Key value propositions include low ESR and high ripple current performance, a wide operating temperature range (−55°C to 105°C), AEC‑Q200 qualification for automotive use, and a 2000‑hour life rating at 105°C for long-term reliability.

Key Features

• Dielectric / Construction Conductive polymer aluminum solid electrolytic capacitor optimized for low ESR and stable performance.
• Capacitance & Voltage 120 µF rated capacitance with tolerance −20% to +20% at 120 Hz, rated voltage 10 V.
• Low ESR ESR of 23 mΩ measured at 20°C and 100 kHz, supporting reduced power loss in high-frequency power circuits.
• High Ripple Current Low-frequency ripple current 1.5 A (120 Hz) and high-frequency ripple current 3.0 A (100 kHz) for smoothing and decoupling in high-demand designs.
• Loss Tangent tanδ = 0.12 (measured at 20°C, 120 Hz, 10 V) for predictable dissipation characteristics.
• Leakage Current Leakage current specified at 240 µA under datasheet measurement conditions.
• Temperature & Lifetime Operating range −55°C to 105°C with a rated load life of 2000 hours at 105°C.
• Automotive Qualification AEC‑Q200 qualified and listed for automotive applications.
• Package & Assembly Surface-mount radial can, size φ8 × 7 mm (D × L), packaged in embossed carrier taping with moisture-proof packing; compatible with lead‑free reflow soldering up to a 260°C peak as specified in the datasheet.
• Compliance & Production Status RoHS compliant and in mass production.

Typical Applications

• Automotive power systems — Bulk smoothing and decoupling where low ESR and high ripple current are required across −55°C to 105°C.
• Power supplies and DC–DC converters — Output filtering and transient suppression in compact SMD assemblies.
• Motor drivers and inverters — Energy smoothing in modules that require high ripple current handling and stable ESR at high frequency.

Unique Advantages

• Low dissipative losses: 23 mΩ ESR at 100 kHz reduces heat generation and improves efficiency in high-frequency power paths.
• High ripple capability: 3.0 A at 100 kHz (and 1.5 A at 120 Hz) supports demanding decoupling and filtering duties under dynamic loads.
• Automotive‑grade reliability: AEC‑Q200 qualification plus a 2000‑hour life rating at 105°C provide assurance for automotive and high-reliability applications.
• Broad temperature tolerance: −55°C to 105°C operation maintains capacitance and impedance stability across harsh environments.
• Compact SMD form factor: φ8 × 7 mm can package enables space-efficient board layouts with surface-mount assembly and moisture-proof taped packaging.
• Manufacturing ready: RoHS compliance and mass-production availability support streamlined procurement and assembly.
